Closest Coastal Departure Hub for the Catalina Islands

Central Guanacaste · Gold Coast

Flamingo & Potrero

The primary mainland departure hub for the Catalina Islands. Because Flamingo and Potrero sit directly opposite the offshore archipelago, morning dive boats reach the Catalina pinnacles in 25–35 minutes and return by midday.

Where You Board Boat: Playa Potrero Bay & Marina Flamingo slipway (plus morning hotel shuttles from Conchal, Brasilito & Tamarindo)

Sites Served: Catalina Islands (Las Catalinas: The Wall, Sombrero, Dirty Rock, Elephant Rock, Punta Guiones) — 25 to 35 minutes offshore

Uninhabited Offshore Volcanic Dive Archipelago (Destination Site)

Offshore Guanacaste · 3–15 Miles off Flamingo & Potrero

An uninhabited chain of 20 volcanic rock islands rising out of deep Pacific currents. Famous for schooling cow-nose and devil rays, whitetip reef sharks, moray eels, and seasonal giant Pacific manta rays (especially December–May).

Where You Board Boat: Passengers DO NOT stay on the Catalina Islands—you board your boat at Playa Potrero, Marina Flamingo, Playas del Coco, or via shuttle from Tamarindo

Sites Served: The Wall, La Pared, Sombrero, Dirty Rock, Punta Sur, Elephant Rock & North Island
