Under The Sea Diving in Costa Rica offers guided dives along the Pacific coast of Guanacaste — from Tamarindo to Playas del Coco — showcasing the region’s diverse underwater world. The team prioritizes safety, environmental protection, and personal attention in small groups, ensuring both beginners and experienced divers have a great experience.
Basic offers
The program is designed for beginners and certified divers and includes typical services such as boat transfer, rental equipment, and meals. Frequently offered formats include:
- Discover Scuba Diving (Intro dive): Pool or shallow-water training followed by two guided dives — ideal for beginners without certification.
- Fun dives for certified divers: Guided dives at nearby spots with experienced guides in small groups.
- Refresher courses (e.g. PADI ReActivate): Compact programs to refresh knowledge and skills before returning to diving.
- Private tours and multi-day options: Flexible bookings for divers seeking more intensive programs or customized trips, including 2- or 3-tank options.
Diving with sharks — the special experience
The shark dive offerings focus on dive sites with regular shark sightings and are especially appealing to experienced divers. Destinations such as the Bat Islands (Islas Murciélago) are known for large gatherings of sharks and are considered a highlight for encounters with various shark species. The tours are accompanied by skilled guides who provide information on species, behavior, and safety rules before the dive.
- Shark dive inclusions: Full-day equipment, usually two dives, drinks and snacks on board, small groups, and expert guidance. A minimum of an Open Water certification is required.
- Bat Islands: Optional 2- or 3-tank days with higher chances of encountering sharks, manta rays, and large schools of fish — more suitable for advanced divers.
- Experience factor: Encounters are never guaranteed, as wild animals are unpredictable; however, experienced guides minimize risks through effective briefings, positioning, and behavior in the water.
Safety & Environmental Protection
Safety and responsible behavior towards the underwater world are a priority on all tours. The staff conducts precise briefings, uses certified equipment, and limits group sizes to avoid disturbing marine life. Many operators also support local conservation projects and promote mindful diving.
