Bajos Castañones
Why dive here
With 217+ marine species recorded in the area - including dolphins, humpback whales, orcas, sea turtles and pufferfish - Bajos Castañones offers some of Caribbean Coast's richest reef diving. Water ranges 29-31°C, warmest March, April, May.
Bajos Castañones, off Costa Rica’s Caribbean coast, offers a genuine glimpse into the region's underwater world. We often find ourselves drifting over healthy coral formations, where schooling fish like snapper and grunt tend to congregate, darting in and out of the nooks. It's a reliable spot for a relaxed dive, usually with decent visibility, making it suitable for divers who appreciate a steady, unhurried exploration of a thriving reef. While not a dramatic drift, it’s a good choice if you're keen to simply soak in the gentle rhythm of the Caribbean.
