When I went snorkeling for the first time in Costa Rica, I had no idea what I was doing. I mean, does it get any cooler than that? Yes, it does. Let me tell you, snorkeling in Costa Rica is one of the best ways to explore underwater marine life. Whether you’re a novice or a seasoned snorkeler, wonder awaits you beneath the turquoise clear waters.
Is Costa Rica Good for Snorkeling?
So should you snorkel in Costa Rica? In short: yes. In long: hell yes. Costa Rica is one of those places that people don’t necessarily think of when they think of snorkeling—but they should! With both a Pacific and Caribbean coast, there’s something for everyone, from coral reefs galore to see what it’s like to swim with white-tip reef sharks (don’t worry, they don’t bite) and trust me, Costa Rica has everything checked off on the list. It may not be the Maldives, but it’s natural, gritty, and unexpectedly diverse.
Why Snorkeling in Costa Rica Should Be on Your List
Haven’t snorkeled in Costa Rica yet? You need to. I’ve seen some colorful and diverse marine life and oceans in my time, but thankfully, nowhere near as many as Costa Rica has to offer. The tropical, vibrant, and clear waters and coral reefs work wonders. Even if you’re floating instead of looking at the schools of marine life surrounding you—dolphins, sea turtles; it’s a whole mood!—you’ll feel as if you’re in another world—and technically, you are.
With places like Isla del Caño, Manuel Antonio, among various others, venturing out into the water is easy and you do not need to be an expert to appreciate all that lies beneath; grab your snorkel gear and get ready to witness one of the world’s most picturesque experiences underwater!

Best Time of Year for Snorkeling in Costa Rica
When’s the best time to go? Well—when you’re staring down into the water for slightly more than rocks? Snorkeling is best during the dry season (December-April) for the Pacific coast; the water is clearer, seas are calmer, and visibility is better. If you’re planning on hitting the Caribbean coastline (Cahuita, Puerto Viejo), the best times to go are September and October. How crazy is it that one whole coast dries up while the other flourishes? That’s Costa Rica.
Top Snorkeling Spots in Costa Rica You Don’t Want to Miss
Of course, this isn’t an all-inclusive list and probably never could be made, as there are many secret beaches and hidden gems around Costa Rica. But for where to look for your day excursions, these are the highest ranked. From an all-day adventure to the most beautiful island to just wading in the shallows, there’s something for all.
Isla del Caño: The Crown Jewel of Costa Rica Snorkeling
This island is number one on my list and a snorkeler’s dream. Usually the water is super clean and the nature phenomenal. Here you have a good chance of swimming with turtles, sharks and even big manta rays. Cano Island is one of the most diverse places on earth.
Snorkeling in Manuel Antonio: Beach, Jungle, and Coral Reefs
Surely, Manuel Antonio National Park should already ring a bell. And I don’t need to wonder why. Known for its lush rainforest environment and sandy beach, it is also a great place for snorkeling. Its calm and clear waters promise a great snorkeling experience, especially for beginners and families. Many tropical fish will swim past you, but with a little luck, you might also see a stingray. Access to beaches such as Playa Espadilla is quite easy; just step into the water. There is no need for a boat, and it offers truly beautiful wildlife along with a wonderful underwater environment.
Snorkeling in Guanacaste – there is a lot of choice
The Guanacaste region of Costa Rica is very touristy and has tons of snorkeling options. There are various highly visited or lesser-known beaches to explore, each attracting its type of marine life. You’ll find plenty of colorful fish, some stingrays, and maybe even a sea turtle or two—though those are more common at the Catalina Islands. But that’s a whole other thing, as you need the boat to get there.
Snorkeling on the Caribbean coast of Costa Rica
The Caribbean coast of Costa Rica, is a vastly different experience than the Pacific coast. Yet, snorkeling opportunities exist over here as well. Cahuita National Park is a popular destination; the reef systems and clarity of the water make for a great escape to snorkel right off the shore with relative ease of locating tropical fish—and even stingrays. Puerto Viejo is another ideal spot, as its slightly warmer waters boast a lot of marine life and quite good visibility.
Do You Need a Tour? Snorkeling with or without a Guide
Honestly — take a tour. Unless you’re a mad boat captain in another life or have a personal yacht with snorkeling equipment hidden in the vault, snorkeling on your own isn’t the smartest idea. Getting stuck twelve miles out to sea with a turtle and no service isn’t ideal, either. With a tour, the guides have better experience navigating the waters than your best high school friend and know all the reefs. They offer equipment, education on the sights, and protection so you don’t come home from vacation with a jellyfish-stinger souvenir. Seriously—get a tour and let the professionals handle the ocean.
Listen, if you’re someone who likes to go it alone—just show me the water—you can absolutely rent things and just do it. Some places in Cahuita even let you walk in from the beach. But if you want to ensure clear, bright waters and not waste time wrestling with currents and paying for unreliable entries, just go with a snorkeling tour. The locals know where the currents go, when the high and low tides are, and what secrets the seas hold. They also bring snacks and good company. If you’re in Uvita or plan to go to Isla del Caño, you absolutely need to use a trusted resource. (We can assist!)
What Marine Life Can You See?
Let’s just say—pack your underwater camera. From parrot fish and moray eels to spotted eagle rays and some sharks. The ocean is basically a National Geographic special. You could be fortunate enough to pass some coral with little critters doing their thing. You could be even more fortunate to have an entire school of silver fish gliding by you all together like a single entity. And when a sea turtle passes by you, distracting you from all your worries—there’s nothing like it; it’s like therapy.

Tips for Snorkeling in Costa Rica
Snorkeling here isn’t exactly plug-and-play. A few pro tips: bring reef-safe sunscreen — Costa Rica takes its marine life seriously. Wear a rash guard because the sun doesn’t mess around, and jellyfish are real. Don’t touch anything underwater (seriously, that coral is older than your great-grandma), and always check the weather before heading out. Rainy season = not-so-great visibility. And if you’re not a strong swimmer, don’t stress—all tours include floatation gear and patient guides who’ve seen it all.
Snorkeling for Families and First-Timers
If you’re a beginner at snorkeling—or taking children for their first adventure—this is the place to be. First, always stay shallow. Unless you’re used to being in deep water, staying shallow is best. Second, ensure your group has all the equipment—fins, masks, and snorkels should be fitted before entering the water. If you’re with kids, they should have a flotation device ensuring stability and comfort while in the water.
Third, don’t forget sunscreen. While it may be easy to forget while focusing on the images below the surface, the tropical sun on your back can get hot very quickly. Finally, take it slow. Many areas in Costa Rica have incredibly clear water where you’ll see a great deal of underwater life, but that shouldn’t be the point—take it slow, enjoy the process and breathe—and enjoy the memories you’ll create under the sea!
My Favorite Snorkeling Memory (And Why I Keep Going Back)
I’ve been in the water thousands of times (I’m a professional diver), but my favorite snorkeling memory came with my daughter on Isla del Caño. We were gliding along the surface, swayed by the calm and clear waters when out of nowhere a sea turtle appeared. I’ve seen thousands of turtles in my diving and snorkeling live — but she didn’t. When my daughter saw this magnificent creature, she gasped and then immediately burst out laughing. She fell in love. It is moments like these that make me want to explore and I was glad that she could experience it with me.

Can You Snorkel During the Rainy Season?
Can you snorkel in the rainy season? I know you’ve been asking this. The answer: yes, absolutely! Snorkeling in the rainy season is entirely possible. The rainy season in Costa Rica (May to November) doesn’t mean it rains every day all day for months on end; it rains almost every day for a brief spell—usually in the afternoon—and most mornings are clear and sunny. Therefore, the tranquil waters call for an actual snorkeling adventure.
In addition, it’s good to snorkel while it rains. Rain helps to clear the waters, washing away sand and debris to enhance visibility. Therefore, as long as you’re mindful of shifting weather and select a local guide for the best travel routes, don’t stress about anything because the rain in Costa Rica won’t keep you out of the water!
