Water activists love Gardner Bay. The shallow aquamarine water is ideal for cooling off on a hot day. Near shore, the waves tend to be mild without currents and the bottom is sandy. Your swimming partners could be playful sea lions, schools of colorful fish and maybe green sea turtles. Snorkelers head to Turtle Rock in the background. Your guide will direct you to the side of the monolith that best matches your experience level. Common sightings are whitetip reef sharks and manta rays. Our group was lucky enough to see breeching whales.
