Two guided dives around Costa Rica’s Catalina Islands for certified divers — volcanic pinnacles, strong currents, and a shot at large pelagics. This day trip from Tamarindo includes equipment use, snacks, and a surface interval between dives.

The boat cuts a low wake across the Pacific and the islands rise like black teeth against the horizon; gulls quarrel and the sea smells of brine and heat. By mid-morning you’re suiting up on deck, instructors running through a concise briefing while the engine hums a steady reassurance. The first descent is a cool drop through blue light; rock pinnacles thrust up from sandy basins and currents tease the reef, bringing schools of jacks and the occasional passing manta.
Difficulty
moderate
Duration
7 hours (approx.)
Fitness Level
Good basic fitness for moving around a boat, carrying light gear, and performing multiple dives; must be comfortable with ocean conditions.
Wildlife
History
The Catalinas are volcanic outcrops whose structure and channels formed from lava flows and sea erosion; local fishing communities historically used these rich waters long before sport diving began.
Conservation
Use reef-safe sunscreen, avoid touching corals, and follow guides’ instructions; local operators often participate in reef cleanups and sustainable tourism efforts.
Reserve your spot on the Fundive Catalina Islands (2 dives, only for certified divers) today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Bring your certification card
Operators require proof of certification and often your logbook; bring both to avoid delays at check-in.
Preempt seasickness
Take motion-sickness medication an hour before departure if you’re prone to nausea; the ride to the islands can be choppy.
Protect against sun
Apply reef-safe sunscreen before boarding and wear a lightweight cover-up — the tropical sun is intense while waiting on deck.
Listen to the dive brief
Currents and local entry/exit techniques vary; follow the guide’s instructions closely for safe drift or wall dives.
Mask & snorkel (personal)
Your own mask saves time on fitting and reduces fogging issues during surface intervals.
3mm shorty or full wetsuit
Water can vary from mid-20s°C to high-20s°C; a 3mm shorty is usually sufficient year-round, thicker in cooler months.
winter
Dive computer
Helps manage no-decompression limits and surface intervals, especially with two dives in a day.
Reef-safe sunscreen & sun shirt
Protects skin between dives and prevents damage to sensitive marine ecosystems.
