- Ongeim’l Tketau (Jellyfish Lake) — The headline act: a marine lake filled with millions of tiny, golden, mostly stingless jellyfish you can float through. The lake’s isolation and evolution created a one-of-a-kind, almost surreal snorkel where the jellyfish’s gentle pulses and the glassy, green-blue water feel unlike any open-ocean swim.
- Ulong Channel & Ulong Island — A drift-snorkel and dive corridor famous for strong currents that bring in big schools and pelagics, then empty into a calm lagoon. Ulong itself has ancient stone platforms and terraces — real archaeological remains — and a gorgeous crescent beach. It’s a mix of marine energy and quiet history that’s very Rock-Islands-specific.
- The Milky Way (silica mud flats / Milky Beach) — Shallow, near-white silica bottoms and warm, milky

- The Milky Way (silica mud flats / Milky Beach) — Shallow, near-white silica bottoms and warm, milky water where locals and visitors smear themselves with the soft limestone mud. It’s basically a natural spa that doubles as a shallow, dreamy beach — great for wading, photos, and the slightly ridiculous mud-facial experience you won’t forget.
- Hidden Beach / Secret Lagoons — Tiny, tucked-away beaches and collapsed-lagoon hollows you swim or kayak into through narrow openings in the rock islands. They have that private, “how-is-this-even-here?” feeling: clear water, impossible cliffs, and a hush that mainstream beaches don’t have. Best reached with a local skipper who knows the small entrances.
- Giant Clam Gardens (shallow clam beds) — Scattered in the southern lagoon are dense patches of giant clams sitting in shallow water, iridescent and impressively huge. Snorkeling these clam gardens gives you an up-close look at wild giant clams and reef life in a setting that feels like a living aquarium — not something you can easily replicate outside Palau’s lagoons.
- Sea caves & limestone arches — The mushroom-shaped, wave-carved limestone islands hide tunnels, caves and natural arches that you can paddle or swim through. The light inside, the echo of drip and splash, and the dramatic rock shapes are pure Rock-Islands business — great for photographers and timid spelunkers alike.
- Coral gardens around Ngeruktabel — Shallow, healthy hard-coral gardens with abundant reef fish right off quiet beaches and channels. These spots are superb for snorkelers who want big coral variety without deep dives — the dense coral formations and the schooling fish here are characteristic of the sheltered southern lagoon environment.
- Blue Holes of the Rock Islands (hidden gem) — Small, photogenic blue holes and sinkhole lagoons scattered through the islands — dramatic depth contrasts and startlingly deep-blue water in tiny circular pools. They’re quieter than the famous marine lakes and feel like secret swim holes locals quietly love. Great for adventurous snorkelers and freedivers.
- Ulong Island ancient terraces & stonework (hidden gem) — Away from the main boat crowds, the old stone platforms and terracing on Ulong are tangible pieces of pre-contact Palauan settlement and ceremonial life. You can climb among the ruins, read the landscape, and get a real sense of long-term human connection to these islands — a cultural layer many tours skim past.
- Mangrove channels and kayak routes through the southern lagoon (hidden gem) — Narrow, quiet channels threading the back-sides of the rock islands where you can kayak, meet local fishers, and watch birdlife up close. These sheltered routes let you experience the lagoon’s ecology, see tiny local hamlets or temporary fishing rigs, and feel like you’ve slipped behind the tourist curtain.
