Guam Snorkel and Dive Spots

Tanguisson Beach

Tangussion: Snorkeling in Shallow water; no diving.
Access: Everyone.

Out past Two Lover’s Point down a thoroughly sketchy road, you will find Tanguisson Beach. It is the site of an old power plant. Now that the plant is shut down, you can go swimming in the area where the hot water used to come out. You can even see some fish there. However, people mostly go to Tanguisson to sit on the beach. The sand is white, the water is blue, and everything is beautiful.

If you look to the right side, you will see a path hidden at the edge of a cove. Following this path takes you to the second part of Tanguisson. This has some iconic rocks that people usually take really stunning pictures with.

Second Beach at Tanguisson

The water is shallow at Tanguisson, but you can swim there. Once upon a time in 2016, it used to be a place where you could see hundreds of sea urchins. However, an explosion in the puffer fish population happened in the spring of 2017, and the puffer fish ate all the sea urchins.

Much of the coral bleached in the big bleaching events in the summer of 2015 and 2017. However, there are still some fish and corals living there. The key thing to remember is to not go past the reef. This is an area that is known for dangerous tides, sharp rocks, and no lifeguards. If you go on a weekday, you will likely be the only one there. If you are swept out to sea, no one will know.

Given that, I recommend that you go swim in the shallows. Look at the fish, take pictures with the rocks, and lounge on the empty beach. Collect sea glass, which is often found there. Have a picnic. But don’t go beyond the reef.

Gab Gab: Snorkeling or Diving in Deep Water.
Access: Restricted. 

If you are looking for some deeper water, Gab Gab Beach is one of the best places to go. It has easy water access because of the stairs, and it even has showers. This is a very popular place for both snorkeling and scuba diving.

However, Gab Gab is on the Navy Base. That means that if you don’t have a military ID, you need to find someone who does in order to go there. This is kind of a bummer if you are a tourist, or a local with no military ID.

On the upside, if you can go there, you will find it less crowded than other places because access is restricted.

Gab Gab Entry Point

I like to go to Gab Gab because it is easy to get into the water. There is no long wade or swim to get out to the reef. And, the water is calm because it is inside of a harbor and is therefore protected from currents and tides that might otherwise prove problematic.

I also like to go to Gab Gab because it is a brilliant place to see turtles. They tend to enjoy spending time in some of the more shallow areas where they can bask in the sun. They also swim over to the boats at the port, and eat algae off the sides. Any day that I go snorkel or dive and see a turtle is a good day in my book. They really are magical.

Gab Gab was effected by the bleaching event in the summer of 2017, and some of the corals in the more shallow areas died. However, the deeper reef is still intact and as beautiful as ever.

Gun Beach: Snorkeling or diving in deep water. 
Access: Everyone. 

Another fabulous place to snorkel or dive is Gun Beach. A quick word of warning: About every six months, someone dies at Gun Beach. Therefore, I need you to listen up to the warning I am about to give you:

This is a reef that is not enclosed in any way. There are waves, currents, and tides. If you see white caps when you look out, do not get in the water. Just hop back in your car and go to a different spot for the day.

The people who die at Gun Beach are usually scuba divers who go out too far, and then get caught in a current and pulled out to sea. They only find the bodies about half the time. Please don’t leave the safety of the reef, and do not go out when the water is choppy.

Gun Beach

Most of the time, the water is smooth as glass and it is perfectly safe to snorkel or dive at Gun Beach. You park out by the Beach Bar, and then walk out to the water. Look for the pipes, and follow them out to the reef.

The water is colder than anywhere else on the island. If you are used to Hawaii water temperatures or colder, you will be fine. However, if you are used to the tropics, I recommend wearing a rash guard and pants.

The reef is beautiful. There are so many kinds of corals and fish! A lot of times you see bigger things too, like giant porcupine puffers, octopus, and huge schools of trigger fish. This is easily one of my favorite places to snorkel, and the swim out really isn’t that bad. I would note that the swim out is much easier at high tide, so keep that in mind. However, you can really make it out at any time of day.

As long as you do it on a calm day, Gun Beach is amazing. I highly recommend it.

The Spanish Steps: Snorkel in Shallow Water; no Diving. 
Access: Restricted. 

The Spanish Steps is another one of the beaches with restricted access. Like Gab Gab, it is on Navel Base Guam. Unlike Gab Gab, there is no easy access to this snorkel spot. You will have to hike in, and the trail is steep and dangerous.

If you go, I recommend hiking boots, long pants, and climbing gloves for the parts so steep that you have to use the ropes provided. It’s not a long high, but it is a very intense high. I wouldn’t bring small children or anyone with any major physical limitations.

However, if you can make the hike, this tiny pocket of life is really very pretty. Obviously you can’t dive there, but the snorkeling is awesome!

Spanish Steps Beach

The Spanish Steps are at the very end of Orote Point. You can’t go out into the open water because the waves and currents are crazy. However, inside the shelter of the rocks, you can see all kinds of fish and larger marine animals.

I have seen some of the best anemones, eels, and schools of fish that I have ever seen on Guam at the Spanish Steps.

Go at High Tide. It is the only time you will be able to swim over the coral. If you go at low tide, you can’t do anything except float in a little pool of water. At high tide, you can glide over coral gardens and see lots of cool fish.

Spanish Steps Under Water

Fish Eye Marine Park: Snorkeling or diving in deep water.
Access: Everyone.

Fish Eye Marine Park is my favorite place on Guam. There is no easy access. At high tide, it is a long swim out. At low tide, it is a slippery and dangerous walk. However, once you get past the long, shallow coral shelf, you will see the most amazing things!

There are a lot of advantages to going to Fish Eye. First, it’s easy to see where to get in. You just head out under the walkway for the observatory. The parking lot is right there. Once you get into deep water, you have so many options!

Fish Eye has a double reef, which means that you can swim along and follow the reef to the left or right. However, you can also go straight out through the deep water. I know that sounds scary. The first time I did it, I was nervous. However, you soon come to a second reef spanning hundreds of meters out to the wave break and full of corals and life.

Fish Eye Marine Park

Another great thing to do at Fish Eye is to swim out to the left. Once you get past the rows of sea grass, you can swim to the left in a HUGE area called the Piti Bomb Hole Preserve. There are so many deep areas where bombs made holes in WWII, and the edges are ringed with exciting corals.

I have seen turtles, sharks, huge schools of all kinds of fish, a barracuda, and so much more! It is the only place around Guam that I have ever seen cowrie shells. There are angelfish and spiny toad fish and all kinds of wonderful things. It is definitely worth checking out.

If you bring scuba gear, I recommend swimming once around the base of the Fish Eye Observatory. It looks like a giant tin can under water, but a huge variety of fish live there because the Fish Eye people regularly throw chum in the water. Then head to the left towards the Piti Bomb Holes, where you will find plenty of deep places to explore.

Fish Eye is often a little crowded. However, there is still nowhere else I love as much. Just be sure to wear a long-sleeve rash guard and long pants. Maybe even a bandanna over your hair and gloves. Jelly fish are often sighted there, and they cant sting you through clothes. It’s better safe than sorry since you want to make sure you have a good time.

If you don’t have clothes to wear in the water, there is a dive shop right across the street from the Marine Park, and they have all kinds of cool options.

Old Wives Beach: Shallow and Deep Water Snorkeling. Diving only by boat. 
Access: Restricted. 

Old Wives Beach is one of the most dangerous beaches I have ever been to. If you feel the need to go, do it at high tide and make sure there are no storms in the area. It is a long slog to get out to the deeper water. The rocks are sharp, and often the waves can be forceful.

Once you get out to where you can easily swim, you have options. To your left you will see a little island, and on the other side of that is Dadi Beach. There are often spinner dolphins sighted there.

To the right is Tarzan Cave and Orote Point.

Old Wives Beach

The sea floor is littered with trash. The military dumped a lot of things there during the war. Make sure you don’t touch anything if you are diving. The military believes that there could be un-exploded munitions down there.

There are lots of turtles and other large animals who like to hide among the trash. If you dive there, it will have to be on a boat out of the Agat Marina, because you would never get out to the deep water with gear on.

That said, I have seen some schools of fish, a dolphin, and several turtles. So, if you are willing to brave the waves, tides, and sharp rocks, you might see some cool stuff.

Tumon Bay: Shallow Snorkeling; No Diving.
Access: Everyone

Tumon Bay is the area where all the resorts are. If you stay at any of the major hotels, this is what you will see from your window and this is the place you can walk to the water.

The water in Tumon Bay is very shallow, even at high tide. There are not many places that you won’t be able to stand up. As long as you stay inside the bay, it is a perfectly safe place to be. However, some people like to go out to the edge of the bay and jump into the deep water. I actually watched someone do this, and they were swept out to sea. The recue crews had a very fast response time, and they were there within minutes. However, they never found the guy’s body.

It’s fine to do a drift dive out there past the reef with one of the tour companies. When a boat is monitoring you and you have dive gear and a safety sausage (required for all boat dives on Guam) then you are safer. But as a swimmer with just a snorkel mask, you chances are not so good.

Tumon Bay

So what can you see in Tumon Bay? Well, count on lots and lots of trigger fish. The most common kind that you will see are called Picasso Trigger Fish here, but in Hawaii I noted that they are called Black Bar Trigger Fish. Either way, we have a lot of them in Tumon Bay. We also have ells, schools of various baby fish, and all kinds of other stuff.

Wear coral shoes even though it seems like the sand is safe. Lots of things live in that sand, and from long-horned cowfish to eels, you don’t want to step on them.

There is a very strong current when there are storms. This can make it a real challenge without fins. Don’t go in the water when the current is really strong because it will suck you over to Gun Beach and out to sea.

Tumon Bay Underwater

Boat Dives

Most dives on Guam are done from a boat, because shore access is limited. There are several options for companies to take you diving, but go with MDA. They are the best, and have access to the most places.

You will need a safety sausage to do a boat dive on Guam. Most boat dives are drift dives because of the currents, and you need to have a way to signal the boat to come pick you up. You can rent all the gear you need except for the safety sausage, so bring one or be prepared to buy one.

Missing Turtle


For more than a year there was a turtle living at Fish Eye Marine Park. He ate the food that they threw in the water for the fish, and visited with the tourists. Some people called him “Larry,” and other people called him “Crush.”

I don’t know what he called himself.

However, he had a small metal tag under each front flipper. One said NOAA Maui USA, and the other said PI2775. He was a green sea turtle who was approximately 50 years of age, and he had a girl turtle in the Piti Bomb Holes near by that he seemed to visit with.

In Mid-July, the tour operators at Fish Eye watched as people from the Department of Agriculture came and took Larry the turtle away.

They said they were taking him “to study,” according to the tour operators.

However, when we called the Department of Agriculture, they  claimed that the turtle “was a nuisance” and so as moved “to the other side of the island.”

Now of course, this was not his first time being caught on Guam. The Marine Biologists at Underwater World took him for study. They weighed him, measured him, and then released him on the other side of the island.

He swam right back, because he enjoys people and food.

However, after the Department of Agriculture claims to have taken him “to the other side of the island,” he did not swim back.

He was a very strong swimmer, and you can be sure that he was capable. How can you be sure, you ask? Well, the people at Underwater World were actually hoping that they could find some evidence that his rear flipper (which was damaged) made it too difficult for him to be in the wild.

They hoped this because they have a rescued sea turtle in the aquarium already, and they hoped for a second.

However, according to the laws governing the treatment of an endangered species, if they are found to be able to survive on their own, they cannot be “rescued.”

Ergo, we know that if the turtle had actually been released by the Department of Agriculture, he would have swam back as he had done before.

We cannot make conclusions from the information that we have. However, we can know two things for sure.

1. Turtle meat fetches a high price on Guam and on the other islands in the chain, because the Native people eat turtle. They know that these turtles are endangered, but some choose to do it anyway. Anyone who took the turtle to sell would have made a LOT of money.

2. They were very suspicious on the phone and asked for my husband’s full name and information before claiming that the turtle was moved. If they are keeping track of who is asking, then one would suggest that they have a reason to be worried.

I am not saying that the Department of Agriculture sold the turtle. However, I am saying without a doubt that they were the last people to have him, and that in two months, he has still not been sighted anywhere else.

If they did not sell him, then their choice to move him certainly seems to have brought about his untimely demise, leaving his girlfriend single and removing his genes from the species.

Furthermore, I spoke with several tour operators who said the initial complaint against the turtle was falsified.

They claim that he was good for business and made the tourists happy and that they would never have done anything that led to his removal.

It is certainly suspicious.

I hope that there will be an investigation, since selling an endangered species for profit is obviously illegal. However, given the diminished funding of the EPA, I worry that justice will not be served.

Side Note:

I have also not seen the female turtle who was hanging around the Piti Bomb Holes near Fish Eye. However, I am not sure that not seeing her is significant. Green Sea Turtles are not social, and it is possible that she was just around to “visit” a boy turtle for a bit.

This is what she looked like:


If you look, you can see that you doesn’t have a tail that extends past her shell, or claws on her flippers. Only males have those traits (which is actually to hold onto the female’s shell.)

She was a little smaller than the male turtle, but they seemed similar in size and age.

The point of this post is that if anyone has any information about the green sea turtle lovingly called “Larry” or “Crush” who used to live at Fish Eye Marine Park, please let me know.

Thank you.

Dive at Fish Eye


My husband got dive certified after me, and his instructor let me tag along. (That’s me above; not that you can tell.)


We went to Fish Eye, which I have snorkeled several times. It was interesting to dive there.


The class went around the base of the Fish Eye tourist attraction.


I followed along, and got pictures of them feeding the fish.


There are all kinds of fish, including groupers and barracudas.


It was a short dive. We only stayed down for about 45 minutes.


However, we got to see a lot of things in that time, and it was fun.

If you are in Guam, I recommend going to Fish Eye Marine Park.


It is a long walk out from shore, but there is a path to follow under the bridge, so it’s not so bad.


And now, my husband and I are both certified to dive!


Fish Eye Marine Park



Since I loved to Guam, I feel like I spend a lot of my time underwater. One of the best places to do that is Fish Eye Marine Park.


Grab your snorkel and wade out under the bridge. When you get into water that is too deep to stand, start swimming to the left.


This is bring you through an ancient forest of coral, and give you the opportunity to see a lot of cool fish.


Normally, you wouldn’t want to feed the fish in the ocean. However, they already feed them as the fish eye tourist attraction, so sometimes I bring along some rice to give them.


They are so used to eating food from humans that they swam all around and it’s cute.


I am trying to learn all the names of the fish, but unfortunately the locals want to teach me the Chamorro words. That’s not something I will ever use outside of Guam.


Once I find a fish guide for this (very remote) part of the Pacific Ocean, I will try to caption future fish pictures with the names of the fish.

In the meantime, here are some pictures of things you can see at Fish Eye.


I think this is a butterfly fish.


And, I know this one is called a flounder.


As for this little guy, I know he’s a rainbow parrot fish.


This seems to have a shape like a damsel fish.


And, this one I do know. It’s a Picasso Triggerfish. They bite, so avoid them.


Here’s a star fish. Ours our blue, but usually they have five arms. I am not sure why this one has six.


And, this is a Picasso Triggerfish with a Wrasse. I really enjoy the different kinds of Wrasse, but I don’t know all their names.

Whatever this one is, it has a great pattern. Shame they’re always digging up the sand so it’s hard to get a good picture.


This is another kind of Triggerfish, but I don’t know its name.


And this is a stag coral forest full of fish. This is to the left of the Fish Eye, swimming into the Piti Bomb Holes. However, there is a lot of stag coral to the right of the bridge as well.


Some of the bomb holes are very deep, but there are lots of shallow places too. Don’t be afraid to swim over the deep parts to get to the shallower parts.


You can go all the way out to the reef, which is past the Fish Eye bridge and the Fish Eye structure at least another 100 meters.


There are great views and huge coral forests covering a huge area, so look around a lot!
