guam snorkeling


Guam is a U.S. island in Micronesia. Clear and tranquil waters at pleasant temperatures make this island an “attraction” for snorkelers worldwide. The impressive scenery (on land and below water) is home to a variety of fish species. In this article we share some basic tips, snorkel locations, the climate and helpful travel inspiration.

How to get there

Antonio B. Won Pat International Airport (aka. Guam International Airport) is the one major airport in Guam. From there you could either hire a car, grab a taxi or use public transportation.

We always use Skyscanner, especially because there’s an option to combine your flight with some great deals on airport car hire. If you don’t have specific travel dates in mind, try their “Flexible dates” function (you’ll get this option once you select your departure date). That’s where we often find some great deals!


Our Favorite Spots In A Nutshell

Some of the most popular spots for snorkeling include Gun Beach, Ypao Beach and Spanish Steps. In northern Guam you’ll find Gun Beach, one of the most beautiful beaches in the world. Ypao Beach is located at the southern tip of Tumon Bay, a well-known marine reserve in the area. We sometimes call Ypao Beach a “natural aquarium” with its coral gardens and colorful fish. Spanish Steps might be the most breathtaking snorkel site on the entire island. Its high cliffs and spectacular views of the Pacific Ocean make it more than “just another snorkel location”.

Tips To Know About

Guam is well-known for it’s scuba diving opportunities. However, don’t get the idea that snorkeling isn’t quite as good. Most locations are easy to access for us snorkelers and even provide great underwater visibility. In other worlds, if you know where you’re going, a diverse marine life is probably waiting right at your doorstep. If you plan to snorkel in Guam, these are some of our basic tips:

  • Be respectful of the reef. They can take hundreds of years to grow, so leave everything the way it is. Avoid snorkel fish food as well.
  • Keep in mind that Spanish Steps, Haputo and Double Reef are located on U.S. military installations and therefore have limited accessibility near the shore. To visit these sites, you’ll have to contact base security for help.
  • Stay within your comfort zone. If currents are too strong, forget about snorkeling for the day.
  • When visiting a site you’ve never visited before, take someone along with you who is familiar with the area. You won’t be the first to lose the location of the car park.
