What are the best snorkeling spots or tours in Aruba?

Aruba offers both shore-based and boat-based snorkeling, with distinct sites for different preferences. For shore access, Malmok Beach features a sunken ship reachable by wading and swimming, with abundant fish and calm currents (water shoes recommended for the rocky bottom). Baby Beach provides another shore option: travelers report snorkeling the channel area near rock formations, following the current back toward shore for optimal fish viewing. Multiple visitors highlight sea turtle snorkeling tours as a standout experience, with one private instructor repeatedly praised for patience, turtle encounters, and included GoPro video at reasonable rates; another family-run operation receives similar recommendations, with the advice to arrive early to avoid crowds from competing boats. One shore-based operator offers equipment, photography, and transportation for those concerned about seasickness. Recent marine life sightings across these sites include turtles, squid, rays, starfish, and diverse fish species.
