Where to Go Scuba Diving in Costa Rica for Beginners

Costa Rica is not just full of lush green forests or jungles and rich in exotic flora and fauna. The country further welcomes you to three main diving areas, namely Coco’s Island, the Pacific Ocean, and the Caribbean Sea. Although Coco’s Island is known for expert divers, the last two realms are still best for beginners.

In all the diving spots in Costa Rica, you may find yourself diving with bull sharks, turtles, eagle rays, manta rays, grunt jacks, white-tipped reef sharks, dolphins, and other marine mammals. If you are lucky enough, you may spot humpback and pilot whales from January to March or June and July as they migrate from the southern hemisphere.

So, before planning your next diving journey, let us help you decide where and when to book your flights to the best diving spots in Costa Rica.

1. Cahuita Reef

Cahuita Reef is Costa Rica’s grand coastal reef sitting within Cahuita National Park. There are three main dive spots in Cahuita Reef, namely Punta Uva, Gandoca, and Cahuita National Park.

2. Isla Uvita

The island of Uvita is just offshore of the country’s second-largest city, Limon. Similar to Cahuita Reef, Isla Uvita comparably has its undersea life beauty and shipwreck.

The island dates back in history when Christopher Columbus first land in the area in 1502. Years ago, Costa Rica’s ship, The Phoenix, dive off of Uvita and unfortunately sank; however, it gave Uvita Island’s undersea a beauty for both scuba divers and marine life.

The Pacific Ocean

Additionally, it has less vegetation, rocky, strong currents, and deserted underwater landscape; however, it doesn’t mean that there is not much marine life. As it happens, you can see hundreds of schools of fish upon diving.

The Pacific Ocean is also known for its shark diving every year, where divers can see shark migration at the same time.

2. Isla Tortuga

Besides marine wildlife, divers can also spot some buried treasures on the island. It offers three shipwrecks where divers have a great opportunity to explore the remains and wonders of sunken vessels.

3. Manuel Antonio

The Manuel Antonio diving sites are located up north of Caño Island. There are fifteen dive sites settled in Manuel Antonio National Park, which provide a different range of marine life and landscapes.
