Catalina Islands

Catalina Islands is one of the favorite sites for anyone scuba diving in Costa Rica. If you love caves, arches and spectacular coral, this is where you will want to head. It is also home to the Pacific Giant Mantas. For more information on Catalina Islands, click HERE.

Cocos Island

Cocos Island is considered by most seasoned divers to be among the top ten places in the world to dive. As a World Heritage site, it is also one of the most beautiful places on earth. Being able to dive with Hammerhead sharks is just one of the most popular things to do here. For more information on Cocos Island, click HERE.

Bat Islands

The Bat Islands are a famous place to dive with Bull sharks instead of the Hammerheads. Located off the coast of Santa Rosa National Park it has been made into a marine preserve so is a perfect place to see all sorts of marine life. For more information on Bat Islands, click HERE.


Virador is a field of boulder set in somewhat of a circular fashion. It ranges in depth from 25-70ft (8-21m) and is so full of amazing things to see that you will probably have to dive a few times to see it all. Its nickname “Turning Point” is a reference to the pattern it lies in.

Many of the fish are fairly friendly, such as the Barberfish and King angelfish who seem to like to have their pictures taken! Others, like the camouflaged scorpion fish and moray eels, like to play hide and seek.

You can also expect to see such critters as the white-tipped reef shark, spotted eagle rays and Latin grunts, just to name a few. A site well worth the time to dive.

Monkey Head

Monkey Head is very close to Virador, and most divers will hit both sites during the same trip. It gets its name from the amazing rock formation that looks just like a monkey’s head that you can see from the surface.

Under the water, you will be amazed with the rich bio-diversity that awaits you. Vibrant corals, amazing macro species and plentiful larger fish make this an ideal place to dive for people of all skill levels.


Herradura is one of the newest places to scuba dive in Costa Rica, and has much to offer divers of all skill levels. One of the most popular underwater attractions is the Giant Oceanic Manta Rays that grace the area each year between December and May.

Tortuga Islands

Tortuga Islands are one of the best places to scuba dive in Costa Rica for shipwrecks. There are three of those sunken treasures here – the Franklin Chang Diaz, the Colonel Alfonso Monge and the Caroline Star.

Isla Uvita

Isla Uvita is located off the coast of Limon on the Atlantic side of the country. There are two awesome shipwrecks to explore here where there is a plethora of marine life. For more information on Isla Uvita Islands, click HERE.

Cahuita Reef

Cahuita Reef is an incredible and magical place to dive. The colorful and spectacular reef fans out from Cahuita Point off the coast of Limon, not far from the shipwrecks of Isla Uvita.

You will be amazed by the beautiful coral, including staghorn and brain coral, as well as sponges and small critters that cover the area. Lobsters and clams make an appearance along with billfish, angelfish, parrotfish, triggerfish and so much more.

The ever-present reef sharks, eagle rays and other pelagics that call Costa Rica home can all be seen here as well. A great site to add to your list.

Caño Island

Caño Island is a magnificent island that is surrounded by underwater pinnacles and amazing coral reefs. The colorful coral and boundless numbers of reef fish are second to none. Of course, the ever-present sharks, rays and eels can be seen as well as many other unique fish.

You can also expect to see many of the larger guys here to entertain you. Critters such as humpback and pilot whales, orcas and dolphins are known to make their presence known. Definitely worth visiting this site.

Puerto Viejo

Puerto Viejo is one of the best places to scuba dive in Costa Rica that sits in the Atlantic ocean. There is a magnificent coral reef that stretches from here to the Panamanian coast where there is amazing soft corals and myriads of reef fish.

When not diving, you may want to try your hand at surfing, which the area is also very popular for.

Light House Rock

Light House Rock is an ideal place for anyone that loves cave diving. Located in the Manuel Antonio National Park, it has amazing volcanic formations underwater that have created great caverns and caves. The waters are calm enough for novice divers, which is sometimes hard to find in this park.

Expect to see a plethora of sea life, including puffers and even the tiny, elusive sea horse, along with the usuals like reef sharks and more. A great dive for everyone.

Pixie Rock

Pixie rock is another dive site in Manuel Antonio National Park that is ideal for less experienced divers, although divers of all skill levels will enjoy it. Currents can get strong at times, so be aware.

The site is relatively shallow, only ranging from 20-40ft which makes it light enough to get a great view of all the beautiful marine life it has to offer. Large schools of angel fish and more will mesmerize you.

Canyon reef

Canyon reef is yet another amazing dive site in the park. It perhaps has the best coral of all the sites yet. There are some great canyons that can run down to 80ft deep that are home to fish like the puffer, rays, sharks and eels. The current is fairly mild here, and you could explore it for hours and not see it all.

Ola Quita

Ola Quita is an island in the Manuel Antonio Park where there is magnificent diving all around the entire island. Octopus is a popular attraction here that you may not be able to see elsewhere.

Ranging from 30-90ft, this site is also a great place to see lobsters, butterfly fish and so much more. The current can get a bit rougher on the bottom, but is well worth spending a lot of time at.

Veinte Seis

Veinte Seis is a spectacular site is you enjoy diving around pinnacles. It is a much deeper dive and is considered to be for advanced divers only.
There are literally hundreds of fish that call this place home, including wahoos, jacks and snappers.

It is a fairly new dive site, and is located much further from shore, so is not crowded with other divers usually. Still in the Manuel Antonio National Park, it is an ideal site to spend the day at.

Isla Largo

Isla Largo is another island in the Manuel Antonio park that has great sites to dive all around it. Underwater you will find many caverns and other rock formations that are home to abundant marine life.

Critters such as the red snapper, scorpion fish, lobsters and puffers will entertain you for hours. This area is considered suitable for divers of intermediate skill level and above.

El Aquario

El Aquario is the last dive site we will mention that lies in the beautiful Manuel Antonio National Park, or Quepos as it is known locally.
This site is shallower than others in the area, ranging from 18-45ft. There are terrific rock formations with a sandbar that runs between them.

You can expect to see turtles and reef sharks resting on the sandy bottom as well as stingrays, eels, lobster and so much more.
When not underwater at any of the sites in the park, be sure to enjoy the natural beauty of the surrounding rain forest, beaches and everything else it has to offer. A perfect place for a vacation.


Sorpresa means “Surprise”, and is appropriately named because of what awaits you underwater. At first it will seem as if you are diving into the open ocean. However, after you drop down to 50ft or so a spectacular oval shaped rock formation comes into view. It drops away to a depth of around 100ft, and is surrounded by hundreds of fish that swim all around you in large schools.

The water here is colder, so a full wetsuit is advised. It is also the reason some more unique fish can be seen here. Jacks, spade fish, and grunts as well as many varieties of rays and sharks can be swimming so close you feel you could reach out and touch them. This is a very exciting place to dive!

How to get to Costa Rica:

While there are a few other possibilities, you will most likely fly into Juan Santamaría International Airport (SJO) in San José.

Or you could fly into the Daniel Oduber Quirós International Airport (LIR) if your final destination is the northwest portions of the country such as Guanacaste or the Nicoya Peninsula.

If you have arranged for a guide, or a liveaboard, they will very likely pick you up from either of these two airports.

If you are traveling on your own, the best way to get yourself and all your gear to a specific location is by taxi. The bus is also a reliable and inexpensive way to get around the country.

Visa info for Americans:

The only requirement for traveling to Costa Rica is a passport that is valid for the entire length of your stay. If you plan to stay more than 90 days however, you will need to apply for an extension at the Office of Temporary Permits.

Many airlines require you to have a round-trip ticket, proving how long you will be there. They will probably add on a $29USD fee, so be sure to ask ahead of time. You do not want to get caught by surprise!


Best times to visit:

Scuba diving Costa Rica can be done all year round. Depending on what you are looking for in diving, some times during the year can be better than others, but they all have their advantages.

December to April is the dry season, and up to March, is the coolest part of the year. The cooler water temperatures is ideal for spotting some of the big guys such as humpback whales, pilot whales, giant manta rays, whale sharks, and more. Of course, this is the best time to get in a little sunbathing as well.

May to November is the rainy season when you can expect a couple of hours of rain each day. The turbulent weather is great for causing nutrient swells which is when the bull sharks are attracted to the Bat Islands and hammerheads to Cocos Islands.

If you are looking for a great adrenalin rush, this is the time to go.

June to September brings about perhaps the best visibility, which can get to around 100ft.
August to December is considered by many to be the best time to visit the Caribbean because the wind is more mild and the sea is at its calmest.

Generally, the air temperature ranges from 27°C/82°F in winter and 33°C/92°F in summer, so is never what most would consider cold. No matter what time of year you choose, you will have an awesome time!
