Why dive here
With 217+ marine species recorded in the area - including dolphins, humpback whales, orcas, sea turtles and pufferfish - Herradura Island offers some of Caribbean Coast's richest diving. Water ranges 29-31°C, warmest March, April, May.
Herradura Island sits off Costa Rica's Caribbean coast, a common stop for local dive operators. It’s generally a relaxed drift, often with good visibility, making it a comfortable spot for newer divers or those looking for an easy day. We often see schooling jacks and snapper here, with turtles cruising along the reef edge. It’s a solid option for a second dive or a simpler afternoon.
