Why dive here
With 173+ marine species recorded in the area - including barracuda, humpback whales, orcas, sea turtles and sperm whales - Catalina Aquarium offers some of Bayahibe & La Romana's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
Catalina Aquarium is a pretty straightforward dive. At a maximum depth of 13 meters, it’s a good spot for a relaxed second dive, or even a snorkel if you’re taking a break from tanks. The reef is home to plenty of the usual Caribbean suspects: we’ve seen nurse sharks resting under ledges, green turtles gliding past, and often find schools of snapper and grunts hanging out. Keep an eye out for the smaller stuff too, like the Blue-spotted Cornetfish or the shy Yellowhead Jawfish peeking from its burrow. While you might not find anything truly exotic here, it’s a reliably pleasant dive with consistently good visibility, often around 20 meters.
