Slightly off the grid, peaceful Playa Jeremi lies just north of Lagun and two miles south of Knipbaii. The sheltered bay embraces a soft, sandy beach with walk-in entry to brain corals, orange cup corals and flowery anemones feeding in the current west of the shore. Farther out, damselfish dart and groupers glide in clear waters near algae-covered boulders in depths of up to 20 feet.
Nestled behind the Royal Naval Dockyard and its historic British fort, this protected lagoon's relaxed atmosphere makes it a good spot for families. Paddle out to the marked snorkel trails (with floating rest stops) and coast through the fringing coral reef. Lifeguards will be happy to tell you whether you've seen a wrasse or a tang. Look for rays around the sunken sloop Seahorse. (441-234-6989)
Renowned for its picture-postcard beach and 650 feet of meandering snorkel trail, Trunk Bay is a Caribbean classic. For an off-the-beaten-path adventure after you cruise the trail, explore both sides of the two rock formations about 200 yards offshore. Near their bases, you're sure to discover bashful critters -- eels, lobsters and the like -- that the rest of the crowd will miss.
