The trailhead sits near the resort's northern edge, unmarked except for a weathered sign half-hidden by tree ferns. You'll descend through pandanus and she-oaks, the path sandy and root-strewn, until the canopy opens onto a forty-meter ribbon of bone-white sand. Granite boulders, some taller than you, anchor both ends of the cove, their surfaces warm enough to lean against while you towel off. The water—pale turquoise close in, deepening to sapphire where the reef begins—stays calm even when Welcome Bay churns.

Snorkeling here feels like swimming inside an aquarium someone forgot to clean: staghorn coral fans out in chest-deep water, and you'll drift past butterflyfish, parrotfish, the occasional black-tip reef shark cruising the drop-off. The best visibility comes between 10 a.m. and 2 p.m., when the sun sits high enough to light the coral gardens. Bring your own gear—the resort rents masks, but the beach itself has no facilities, no kiosk, no shower.
Most visitors never leave Nudey Beach or the main resort strand, which means Secret Garden stays blissfully underpopulated. You'll share the sand with a handful of couples, a kayaker or two paddling over from Welcome Bay. By late afternoon the shade from the hillside creeps across the cove, and the water takes on a glassy, pewter sheen. Pack out everything you pack in—there's no rubbish bin, and the island's brush turkeys will shred anything edible left unattended.
