Explore Catalina Islands
Catalina Islands are located 12 kilometres off the coast of Northern Guanacaste in Costa Rica on the Pacific Ocean side. This is one of the most popular diving destinations in Costa Rica and definitely deserves this reputation. The islands are of volcanic and sedimentary nature and this is represented in the underwater topography; this area is not known for its large colourful coral reefs, but for its thrilling, volcanic rock formations and high abundance of marine life, big and small. There are caves, caverns and arches to explore here, and some of these rock formations do have some colourful soft corals on them and large schools of colourful fish which brighten up these dive sites. There are many dive centres and dive resorts on the coast of Guanacaste which operate around Catalina Island due to it being such a popular destination. Some of the spectacle species here include Sea Turtles, Giant Pacific Manta Rays and on the luckiest days, Tiger Sharks.

The best Months to Dive at Catalina Islands
Due to the Catalina Islands being located so far off the coast, there are fewer factors that affect visibility.

Diving here is possible year-round with pleasant tropical air temperatures and warm water temperatures ranging between 24°C–29°C/75°F–84°F. The rainy season runs from May to November, which means showers in the afternoon but still enough possibility to dive. The dry season from December to April means perfect diving conditions. The best months for seeing a high abundance of different species of rays are January to March.
