Best Places in Costa Rica for Scuba Diving 

Over the past two decades or so, people around the world have simply gone bonkers about scuba diving. This mode of underwater diving where the diver uses a self-contained breathing apparatus has quickly become one of the most demanded leisure time  activities amongst newcomers, aficionados, and experts.

Scuba diving is considered both as a recreational and professional pursuit; it also has a number of applications for scientific study purposes, military, public safety, and commercial uses.

According to a recent report by the Sports and Fitness Industry Association (SFIA), more than 1.1% of the US population or 3.145 million Americans participate in scuba diving.

Furthermore, 57% of core participants are between the ages 25-54 years old, while 21.8% of core participants are older than 54 years of age. However, scuba diving can, at times, result in injury and divers face inconveniences due to inadequate physical fitness.

With that out of the way, let’s take a quick look at some of the best places that you can go for scuba diving in Costa Rica.

For safety purposes, We have mentioned the difficulty level along with each venue depending on popular reviews and endurance level requirements.

Costa Rica Dive Sites at a Glance

Costa Rica splits into two diving coasts. The Pacific holds most of the dive sites and the big animals. The Caribbean is smaller, shallower, and calmer. Here’s a fast read on the main spots before the full breakdown below.

• Playa del Coco (Guanacaste) — beginner friendly, dive all year. Reef sharks, rays, turtles. Main launch town.
• Catalina Islands — advanced. Manta rays and big pelagics. Best around November to May.
• Bat Islands — advanced. Bull sharks. Best late May into November.
• Caño Island — certified divers. Reef, sharks, mantas. Best late December to early March.
• Cocos Island — experienced only. Hammerhead schools. Liveaboard access, books out fast.
• Tortuga Islands — beginner friendly. Wrecks and reef off the Nicoya Peninsula.
• Cahuita / Caribbean — beginner friendly. Coral reef. Best February to April.

Cocos Island

Approximately 550 km away from the mainland, the Isla del Coco is administered by Costa Rica. The entirety of the island has been a Costa Rican National Park since 1978, and as such there are no permanent inhabitants other than park rangers.

This island is an ideal spot of scuba divers, and amongst various venues, there are two that stand out the most.

·  Dirty Rock (for beginners)

Reputedly the most beautiful dive set and also the most famous at Cocos Island, the Dirty Rock is where you can get to see schools of hammerhead and  Galapagos sharks along with green turtles and eagle rays. You will also encounter octopuses and large schools of fishes in this area.

·  Bajo Alcyone (for experts)

Another popular dive site at Cocos Island, the Bajo Alcyone is where you will find yellowfin tunas, marble rays, oceanic blacktip sharks, white tip reef sharks, silky sharks, hammerheads, and large schools of jacks. This site, however, is an underwater seamount and this means there can be strong currents which is why We recommend that you dive here only if you are a pro at scuba diving.

Cano Island

Located in the Bahia de Corcovado in Osa Costa Rica, Isla del Cano is a small island and is  protected as a national park under the Osa Conservation Area. It is undoubtedly a popular tourist destination for whale watching and ecotourism, making it an ideal spot for scuba divers.

·       Coral Gardens (for beginners)

Located some 40-minute boat ride from the island, the warm waters at Coral Gardens are abundant with marine life. If you are a beginner there are people around that can arrange for you a snorkeling activity as well. Some common species that you will encounter include sea turtles, crabs, lobsters, eels, manta rays, stingrays, humpback whales, octopus, and many more. Enjoy relaxed dives featuring a beautiful coral garden with profusions of hard coral.

·  El Bajo del Diablo (for versatile divers)

One of the local highlights at Cano Island is the Bajo del Diablo, where a formation of submerged mountains is able to attract an incredible variety of marine life. These can include various species of fish along with sharks, moray eels, jacks, snappers, barracuda, puffers, and the parrotfish. The dive site may present some visibility issues, and so it is recommended for experienced divers. Quick note: the name of the place translates to “The Devil’s Pinnacle”, thus you know that it is a high demanding dive site.

·  Shark Cave (for versatile divers)

Also known as Cueva Del Tiburon, the Shark Cave is an exciting dive spot that features a small cave that is home to sharks.

It is best that you not enter the cave and disturb the habitat of these carnivorous creatures. Other than sharks, you also get to see up to five different types of eels and other marine life such as damsels and the parrotfish.

·  El Bajo del Diablo Deep (for experts)

Now you may be wondering why I am repeating myself here. Actually, the thing is that El Bajo del Diablo Deep is considered a different dive site in its own right. This is where divers move further into the ocean where depths can range from 6-115 ft.

Advised only for advanced divers, this is the place where the big divers play. Due to stronger currents and deeper bottoms that can exceed depths of 80 feet, you are bound to encounter a plethora of predators as well as pelagic life dwelling in these waters.

Catalina Islands

A quick 25-30 minute boat ride from Playa Ocotal will take you to Catalina Island where the place is famous for Giant Mantas of the Pacific that frequently crowd the area throughout the year.

There are numerous dive sites all around the island and are indeed some of the best spots for scuba divers in Costa Rica.

·  Los Sombreros (for beginners)

One of the best sites for amateurs who can stay shallow if they need to, Los Sombreros offers easy access and therefore is a great choice for beginners. Apart from mantas divers can get to see eagle rays and many other marine creatures. You can reach this dive site from Playa Flamingo. At 30-45 feet towards the north, you will come across seahorses, harlequin shrimps, scorpionfish, lobsters, and other marine life.

·  El Clasico (for versatile divers)

If you want to have a go at watching white tip reef sharks at their favorite resting place, then the dive at El Clasico can offer you your fill. Regarded as an excellent dive spot by numerous divers at Rocket Frog Divers, dive times can be more than 50 minutes while temperatures remain bearable at 26 degree Celsius. However, visibility of not more than 5 meters mandates that experienced divers approach this site.

·   Roca Sucia (for experts)

The highlights for this place include white tip sharks, giant morays, and schools of various other fishes. Roca Sucia is a favorite dive site for talented scuba divers offering you depths of 30 meters.

However, some divers have reported visibility issues, and the bottom of the dive site is mostly volcanic. Diving is available all year round, and temperature can reach around 27 degrees Celsius. For some, this site may be a new discovery altogether.

·   Bat Islands (for experts)

A premier destination for scuba divers in all of Costa Rica, Bat Islands is also known as Isla Murcielago. Located in the far north of the Guanacaste off the coast of Santa Rosa National Park, this is where you are going to meet the bull sharks. Overall the entire site is overflowing with an abundance of marine life, and this makes it a diver’s heaven especially for those who are infatuated by the very big and large bull sharks. You can reach this dive site through the Playa Ocotal.

Tortuga Island

Tortuga Island has an English name which is Turtle Island. It is also considered to be one of Costa Rica’s most pleasant, relaxing, and serene islands.

Thus Tortuga Island is quite popular for tourists  offering various other attractions such as canopy tours and zip lines to spoil you rotten with all-round entertainment. The area also serves as a great spot for snorkeling and scuba diving activities, especially for those who love shipwrecks. While there are shallow sites for beginners for more advanced divers, there are deeper sites as well.

Gandoca Manzanillo National Wildlife Refuge

Situated in one of the most stunningly good-looking expanses of Costa Rica, the Gandoca Manzanillo National Wildlife Refuge is located near the Panama crossing border. A protected region for some plant life and wildlife that pose a vulnerability to complete disappearance as well as safeguarding the solitary orey and jolillo palm marshlands in Costa Rica is the wildlife region.

For divers, this is probably the most ultimate snorkeling and scuba diving site in the Caribbean coastline. There are numerous coral reefs and small islands that are visited by a huge number of dolphins, manatees, and sea turtles. Students who seek the best dissertation writing services should consider visiting this place once in a while to find relief from academic stress.

Cahuita National Park

Located on the southern Caribbean coast in the Limon Province, the Cahuita National Park is a marine and terrestrial national park protecting the beaches and lowlands. It is a popular tourism site and attracts various visitors looking for snorkeling and scuba diving activities. This place is a nesting ground for sea turtles and contains coralline reefs.

For the best visibility, you can visit this place during February and through April. There is a gigantic 600-acre reef that is known to inhabit more than 35 species of coral, over 140 species of molluscs, 123 species of fish, and around 44 species of crustaceans. Students who buy essay online can read all about this amazing place and plan their upcoming visits or field trips.

Playa del Coco and Guanacaste 

Most Costa Rica diving runs out of Guanacaste. This is the dry, sunny northwest of the country. Playa del Coco, or El Coco, is the main dive town. It’s laid back, easy to reach, and kind to new divers. Most Pacific dive shops sit right here.

Why does this town matter so much? Because it’s the gateway to two of the country’s best dive areas. The Catalina Islands sit about 90 minutes out by boat. The Bat Islands are a longer run further north. Base yourself in Coco and you can dive both.

The house reefs around Coco stay gentle. Depths are shallow and currents are mild. You’ll meet white-tip reef sharks, stingrays, eagle rays, and turtles. For first-timers in Costa Rica, this is the place to start. Begin here.

Coco is also a real town, not just a dock. There’s food, nightlife, and easy beach days between dives. Non-diving partners and kids won’t get bored. That makes it an easy pick for a mixed group.

Best Time to Scuba Dive in Costa Rica

There’s no single best month to dive here. It depends on what you want to see. The dry season runs December to April. That’s when the Pacific water turns clearest. Calm seas, good light, easy boat rides.

Then there’s the green season, May to November. It brings more rain. The water fills with plankton. Visibility drops, sometimes hard. But the big animals roll in to feed. Mantas and whale sharks love this water.

So what shows up, and when? Manta rays crowd the Catalina Islands from about November to May. Bull sharks rule the Bat Islands from late May into November. Whale sharks and the biggest pelagics turn up most from September to March. Hammerheads school at Cocos Island all year. Caño Island gets its mantas from late December to early March.

Here’s an honest take for beginners. The dry season is the safer bet. Clear water and calm seas make those first dives easier. Chase the green-season giants once you’ve got some dives logged.

Costa Rica Scuba Diving for Beginners

Beginners are not shut out of Costa Rica. Far from it. Several sites are built for first-timers. Playa del Coco leads the list. Shallow depths, mild currents, warm water, and plenty of fish.

The Pacific house reefs around Coco rarely drop past 60 feet. You’ll see reef sharks, rays, and turtles without fighting any current. The Caribbean side helps too. Cahuita and the southern reefs are shallow and calm.

What should a new diver skip at first? The hard stuff. The Bat Islands run deep with strong current and cold water. Cocos Island is a serious, experienced-diver trip. Save both for later. Build your dives up first.

One more tip people forget. Book a refresher if you haven’t dived in a year or two. Skills fade fast. A quick refresher dive sorts that out before the real fun starts.

Do You Need to Be Certified to Dive in Costa Rica?

Yes, you can learn to dive in Costa Rica. No card required to get started. Most dive shops run a Discover Scuba Diving session. It’s a guided shallow dive with an instructor. No course, no exam, just a taste of the sport.

Want to dive on your own? Then you’ll need an Open Water cert. PADI and SSI dive centers run full courses across Guanacaste and Manuel Antonio. A course takes a few days. You leave a certified diver.

Already certified? Bring your card and your logbook. The tougher sites want proof and some experience behind you. Caño Island doesn’t teach beginner courses and needs you certified first. The Bat Islands and Cocos want Advanced Open Water and logged dives. Don’t show up underqualified for those.

Water Temperature, Visibility, and What to Wear

Warm water defines most Costa Rica diving. The Pacific surface usually sits in the high 70s to mid 80s Fahrenheit. That’s roughly 26 to 29 degrees Celsius. Easy, pleasant diving for most of the year.

There’s a catch, though. Seasonal winds push cold, nutrient-rich water up from the deep. This happens most around the Bat Islands and the Catalinas. Temperatures down there can fall into the low 70s or colder at depth. That cold water is exactly why the big animals come.

So how do you dress for it? A 3mm wetsuit handles most of the Pacific and the Caribbean. Pack a 5mm or a hood for the Bat Islands and deeper sites. Better warm than shivering.

Visibility swings a lot by site and season. On a good dry-season day it can reach 60 to 100 feet. Plankton season cuts that down, sometimes to a few meters. Lower visibility is the trade-off for mantas and whale sharks. Worth it.

Marine Life You’ll See Diving in Costa Rica

Sharks pull most divers to Costa Rica. And they deliver. White-tip reef sharks turn up at nearly every Pacific site, all year. Bull sharks own the Bat Islands. Scalloped hammerheads school by the hundreds at Cocos Island. Nurse sharks and the odd whale shark round it out.

Rays are everywhere too. The headline act is the Pacific giant manta. You’ll find them at the Catalinas, Caño, and Cocos. Mobula rays, eagle rays, southern stingrays, and marble rays fill out the cast.

Turtles are a near-lock on most dives. Green, hawksbill, and olive ridley all swim these waters. Guanacaste beaches even host nesting leatherbacks in season. It’s a turtle-rich coast.

Then there’s everything else. Humpback whales and dolphins cruise the Pacific and often show from the boat. Below, you’ll spot moray eels, octopus, seahorses, groupers, and huge schools of jacks and snapper. Few coasts pack in this much life.

How to Get to Costa Rica and Its Dive Sites

Two international airports put you near the water. San José (SJO) sits in the center of the country. Liberia (LIR) sits up in the northwest. Both take direct flights from the US.

Heading to Guanacaste? Fly into Liberia. It’s the closest airport to Playa del Coco and the Pacific dive shops. The drive from LIR runs well under an hour. That’s the easy route for most diving trips.

Going to Cocos Island? That’s a different plan. Cocos is liveaboard-only, with boats leaving from Puntarenas. Fly into San José for that one. Book the liveaboard far ahead, because spots fill up fast.

What about Caño Island and the Caribbean? For Caño, fly into San José, then reach Drake Bay by small plane or by road and boat. For Cahuita and the southern reefs, San José is again your gateway. Plan the last leg in advance.

Conclusion

Having progressive environmental policies, Costa Rica meets all five UNDP criteria to measure. Costa Rica is the only country to meet these criteria that measures environmental sustainability. By 2019 more than 99.62% of its electricity will be generated from green sources. The reason I am mentioning is because as a place that is taking huge steps towards environmental protection, you as a tourist should also follow best practices whenever you chose to visit this amazing place.

With this message, I hope you would also help younger divers to experience the amazing scuba diving sites this place to offers. Together we can help in preserving this amazing venue overflowing with biodiversity for future generations to enjoy and enthral themselves.
