Explore Guanacaste

Guanacaste is located in the northwest of Costa Rica, bordering the Pacific Ocean, and is known for its beaches and rich biodiversity, both above and below the water. This area embodies what the Pacific Ocean has to offer. It may not be the location to visit if flourishing, colorful coral reefs are what divers are looking for, but it does provide some really stunning and unique volcanic rock formation topography and an abundance of larger marine species for divers to admire. This tropical area has pleasant weather conditions throughout the year with water temperatures ranging between 23°C–32°C/73°F–90°F. The colder winter months, January and February, bring with them migratory species, including humpback whales, manta rays, and pilot whales, while the rainy season, which runs from May to November, increases the nutrients in the water and attracts more shark species, including whitetip reef sharks and bull sharks. The main three areas visited from the dive centers and dive resorts here are Catalina Island, Playa del Coco, and Bat Island.
