Best Time to Snorkel Boca Catalina, Aruba
Boca Catalina is Aruba's premier sea turtle snorkeling spot. The wide shallow bay with seagrass meadows attracts green and hawksbill turtles year-round, but when you arrive makes an enormous difference to the quality of your experience.
Best Season: December Through April
The dry-season trade winds keep Boca Catalina's west-facing bay glassy smooth. Visibility peaks at 18-22 metres, water temperatures sit at a comfortable 26-27°C, and the seagrass meadows attract the highest concentration of feeding sea turtles. Hawksbill turtles are particularly common January through March.
Avoid the Tour Boat Rush
Boca Catalina is one of the most popular catamaran and boat tour stops in Aruba. Boat groups typically arrive between 10:00 AM and 2:00 PM and can deposit 40-80 snorkelers in the water simultaneously. The turtles retreat into deeper water when the bay becomes crowded. Arrive no later than 8:00 AM.

Tips for Seeing Sea Turtles
- Stay low and slow -- approach from the side, never from above; maintain 2 metres distance
- Explore the seagrass zone -- turtles feed on seagrass but rest on the reef ledge
- Look left of the main bay -- a small rocky reef section sees fewer visitors and often holds juvenile nurse sharks
