Exploring The Top-Notch Scuba Diving Destinations In Costa Rica For 2023

In Costa Rica, scuba diving and snorkeling may be an enchanted adventure due to the abundance of nutrients in the country’s coastal waters. The visibility for scuba diving is between 30 and 100 feet due to the clarity of the water, ensuring that you will see a wide variety of marine species. Divers may even find that sightings of “large animals,” such as whale sharks, manta rays, dolphins, sea turtles, and even the rare humpback whale, divert their attention away from the breathtaking beauty of the underwater world.

Snorkeling is a fun and relaxing alternative to scuba diving for those who do not feel comfortable breathing underwater for extended periods of time. Snorkeling opportunities in Costa Rica range from those suitable for novices to those more advanced. There are various places around the beaches of Costa Rica that provide scuba diving and snorkeling trips; however, the following places are what we consider to be the greatest places to do scuba diving and snorkeling in all of Costa Rica.

Scuba diving in Costa Rica

Costa Rica, which literally means “rich coast” in Spanish, is renowned for its verdant tropical forests and a plethora of different kinds of animals, both above and below the ocean. The nation may be found in Central America and occupies a sliver of territory that is dominated by volcanoes. This region is sandwiched between the Pacific Ocean and the southern Caribbean Sea. Some of the world’s most diverse ecosystems may be found in this part of the globe due to the favorable conditions provided by the region’s tropical temperature and its wide array of habitats, which are home to various rare and endangered species.

Large pelagic fish and animals are drawn to the coast of Costa Rica’s western coast by nutrient-rich upwellings and currents from the Pacific Ocean. Nearby islands, such as the Catalinas and the Bat Islands, provide an opportunity for interesting day trips. In addition, the flagship diving spot of Costa Rica, Cocos Island, can be found 340 miles farther out to sea and is famous across the world as a wonderful hammerhead shark destination.

On the island’s eastern shore, the Caribbean’s colorful reefs conceal protected areas that have not been well investigated. The Caribbean dive sites of Costa Rica provide a more laid-back alternative to the huge ocean diving found on the west coast. These sites are also rich in tropical marine life and are excellent for first-time divers and snorkelers.

Gandoca Manzanillo Wildlife Refuge

The Gandoca Manzanillo Wildlife Refuge is often regarded as the location that offers the finest opportunities for scuba diving and snorkeling. The combination of the coral reef, small bays, inlets, and islands creates the ideal environment for the presence of marine life. Dolphins, manatees, crocodiles, and sea turtles are just a few of the wildlife that makes Gandoca Manzanillo their home. Sea turtle nesting season runs from March to July.

The National Park of Cahuita

One of the biggest live coral reefs off the coast of Costa Rica may be found at Cahuita National Park, which is located on the Southern Caribbean Coast. This reef is home to over 35 different varieties of coral. The coastal park is next to a path that runs for 5.6 miles along the seashore. After a journey of around 2.35 kilometers, you will arrive at Punta Cahuita, which is regarded as one of the highest locations in the area for snorkeling. This part of the nation has a reputation for having wet weather.

If you are able to be flexible with your travel dates, you should try to schedule your trip for the drier months of September and October, more especially for the vibrant reggae-style event known as Carnival.

Caño Island Biological Reserve

Scuba divers, both beginners and seasoned veterans may travel below the surface at a variety of breathtaking spots all throughout the Osa Peninsula to experience a whole other world. These destinations range in difficulty from easy to difficult. Due to the clarity of the Pacific Ocean’s waters, visibility may range anywhere from 30 to 100 feet throughout the whole year.

This ensures that visitors to Costa Rica’s underwater world always have an unobstructed view of the diverse array of marine species that they are swimming with. The Cao Island Biological Reserve is home to a staggering number of one-of-a-kind dive sites, more than any other single location on the planet. Watch out for white-tip and bull sharks while you’re out in the water.

Spotted dolphins are naturally inquisitive and may interact with the boat by playing in its wake. Visitors often come face to face with schools consisting of hundreds of fish, so prepare to see more fish than you can bear. As a result of Cano Island’s designation as a biological reserve, there are only ten divers permitted in the sea at any one time, and there are five specific areas allowed for diving.


Cocos Island is undeniably the most well-known location for scuba divers to visit in all of Costa Rica. It is only accessible via liveaboard charter because of its remote location, around 550 kilometers/340 miles off the west coast of the nation. As a consequence of this, vacations to Cocos are not inexpensive, yet, the awe-inspiring experiences that are in store for visitors more than justify the cost. The island is encircled by a vast oceanic body of water that is characterized by towering pinnacles and precipitous reef cliffs. Because of this abrupt shift in terrain, nutrient-rich upwellings are created, which in turn attract a wide variety of pelagic organisms.

At Cocos, there are around 20 distinct dive locations, and possible wildlife sightings include everything from large schools of gamefish like trevally and tuna to dolphins, sailfish, turtles, and manta rays. However, sharks are the primary source of entertainment at this location.

Galapagos sharks, bull sharks, tiger sharks, silky sharks, and white-tip reef sharks are among the species that frequent the area often. The large schools of scalloped hammerheads that may be seen in one of the most well-known dive locations, Bajo Alcyone, are recognized all over the globe. The visibility extends from 10 to 30 meters or 33 to 100 feet. The months of June through November, which are the months during which plankton blooms, attract the largest diversity of species and provide the finest opportunities for wildlife viewing.

Cocos Island is known for having dive locations that are often rather deep and are washed by strong currents. As a consequence of this, divers are required to have a high level of water self-assurance and certification that is similar to that of PADI’s Advanced Open Water Diver.


The Catalina Islands are an archipelago of rough and rocky outcrops that may be found just off the coast of Costa Rica’s Guanacaste region in the country’s far northwestern corner. The islands are well known for their enormous manta rays and may be reached by taking day excursions with diving companies that are situated in Playas del Coco. Mantas may be seen there throughout the whole year. However, the months of November through May are when the chances of seeing one are highest. There are also significant numbers of other types of rays, such as spotted eagle rays, mobula rays, and bullseye round stingrays.

The Catalina Islands provide more than just the opportunity to see rays. Divers with experience have a better chance of seeing sharks, turtles, and schools of brightly colored fish. There is a good chance of seeing several cetacean species, such as humpbacks and orcas, during the voyage out to the islands. A certification for advanced conditions is recommended here since the circumstances here often entail high currents.

Bat islands

The Bat Islands, also known as Islas Murcielagos, are another fantastic choice for scuba divers in the Guanacaste area. These islands may be reached from Playas del Coco. You will need a lot of bravery, though, since here is the territory of the enormous bull shark, and it is one of the few sites in the world where it is possible to dive with the species without being enclosed in a cage. Around a location named fittingly as the Big Scare, the bull sharks like to assemble on their own own.

After a hasty descent (which is required by safe diving standards), the remainder of the dive is spent fumbling about the jagged bottom in search of sharks. The visibility may range from as much as 100 feet or 30 meters on one day to as little as 16 feet or 5 meters on the next day. Other notable dive sites include Bajo Negro, a steep pinnacle famed for its schools of gamefish and probable views of manta rays. The Big Scare is not the only diving spot in the area.

Gulf of Papagayo for Snorkeling

The Gulf of Papagayo, which can be found in the northwestern province of Guanacaste and is located off the Papagayo Peninsula, is an excellent place to go snorkeling because of its placid and sheltered inlets and bays. In spite of its status as a developing tourist destination, the Papagayo Peninsula has managed to preserve its natural authenticity by retaining its verdant tropical scenery and many species of native flora and fauna.

Gulfo Dulce

Because the Gulfo Dulce on the Osa Peninsula is home to both distinct marine and terrestrial habitats, it is an ideal vacation spot for those who are passionate about animals in both the ocean and the rainforest. In addition, it is home to a large population of spinner dolphins, which means that you may be lucky enough to see an impromptu dolphin show while you are out snorkeling.

The spinner dolphins are able to congregate in large groups called superpods, and it is a treat to see them either from the boat or from a close distance below the surface. It is impossible to observe all of the marine life that lives on the reefs off the coast in a single excursion; thus, you should not be shocked if you find yourself longing to return.

Tortuga island

This island may be found in the Gulf of Nicoya. It is an excellent all-around destination for divers of all skill levels due to the variety of shallow and deep locations that are located there. In particular, it is well recognized as the “wreck diving capital” of the nation.

There are three ships in the vicinity that may be investigated: the Caroline Star, the Franklin Chang Diaz, and the Coronel Lafonso Monge. Due to its unusual location in just 52 feet (16 meters) of water, the Coronel Lafonso Monge is within reach of even inexperienced divers.

The Franklin Chang Diaz was a Coast Guard vessel that has since been abandoned and is now home to big schools of jack and snapper. The Caroline Star is the wreck that is the deepest at 100 feet/30 meters. In the hold of the Caroline Star, dozing white-tip reef sharks are a common sight, and seeing them at the nearby diving spot La Cueva is one of the highlights of reef diving in this area. Other animals to keep an eye out for include whales and manta rays, which may be seen between the months of December and April (August to January). Tortuga Island Dive Club, which is located in Montezuma, is able to arrange day excursions from the mainland.
