More ways to explore the area's outdoor wonders
The morning air at Tamarindo is taut with salt and the low hum of a waiting skiff. Guests gather at the dive center by 6:40 a.m., try on wetsuits and fins under the awning, then slip into a 45‑minute boat ride that pushes past surf‑cut rocks toward the Catalinas Islands. The islands sit as dark, volcanic outcrops where currents crowd nutrient-rich water into pockets and reefs brim with schooling fish.

Bring a well‑fitting mask
Using your own properly sealed mask speeds skill drills and reduces fogging during the refresher; rentals are available but fit varies.

Declare any heart, spinal or pregnancy concerns at booking — operators will refuse participation for safety reasons.
