Palau

Drowned limestone islands, a jellyfish lake and current-fed channels.

The Rock Islands

Best for

Palau packs an unusual range into a small island group: drowned limestone Rock Islands with shallow, sheltered bays inside them, a marine lake you can snorkel among golden jellyfish, and channels where the tide carries sharks and mantas past. Almost all of it is reached by boat, and Palau manages its water seriously — permits, a conservation pledge and local rules are part of the trip, not an afterthought.

Key sites to explore

The distinctive underwater sights worth planning around. Descriptions are curated planning info — always verify local access, rules and conditions before you set out.

01

Nikko Bay

Lagoon

📍 The Rock Islands, off Urukthapel (Ngeruktabel)

A sheltered inlet among the Rock Islands with shallow coral, calm water and the karst walls that give the whole archipelago its look. The coral here sits shallow enough to snorkel properly rather than glance at, and the bay is protected enough to be workable on a windy day when the outer reef is not an option.

The Rock Islands are managed water: boats need permits, and some bays are closed or restricted at different times. Go with a local operator who knows what is currently open rather than assuming any bay is fair game.

02

Clam City

Reef

📍 Off Mecherchar (Eil Malk), the Rock Islands

A shallow patch reef named for its giant clams — several of them large and very old — sitting in clear, calm water alongside coral heads and reef fish. It is among the easiest and most reliable snorkels in the Rock Islands, and it pairs naturally with a lake stop on the same island.

The clams are living, protected animals: look, do not touch, and never stand on the coral around them. Follow your guide's directions on where the boat may moor.

03

Jellyfish Lake (Ongeim'l Tketau)

Lagoon

📍 Mecherchar (Eil Malk), the Rock Islands

A marine lake cut off from the sea, reached by a short, steep trail across the island, where golden jellyfish drift in the water. Their sting is not felt by people, and snorkeling among them has been one of Palau's signature experiences for decades. The lake's jellyfish population is fragile and has been hit by drought and warm-water events before, so its status changes over time.

Verify before you plan around it: the lake has been closed to visitors at times to let the jellyfish recover, and permission, the trail and the rules — no scuba gear, no lifting jellyfish out of the water, no sunscreen on the swim — are all locally managed. Confirm what is currently allowed with a local operator or the park office.

04

Milky Way

Lagoon

📍 The Rock Islands, near Mecherchar

A shallow, enclosed patch of the Rock Islands where fine white calcium-rich mud clouds the water. It is a swim-and-mud novelty rather than a reef: the draw is the milky water and the mud itself, and boats stop here as a break between coral sites.

There is very little reef life here and the bottom is soft mud — do not stand on it, do not stir it up around other swimmers, and treat the mud as a bit of fun rather than anything with a claimed health benefit.

05

German Channel

Megafauna point

📍 Between Ngemelis and the barrier reef, southern Rock Islands

A channel cut through the barrier reef in the German colonial era, now one of Palau's best-known sites — manta rays at cleaning stations along the channel edges, plus grey reef and whitetip sharks. The megafauna is the point; the coral and reef fish along the channel are the setting.

This is current-carried water and the cleaning stations sit at diving depth, so the mantas and sharks are mostly seen by divers. A snorkel here is a boat-and-tide call, not a guaranteed encounter — it depends on the operator judging the flow safe. And be clear about the rest of Palau's fame: the celebrated walls such as Blue Corner are dive sites, not snorkel sites.

Snorkeling in Palau: quick answers

Can you snorkel Jellyfish Lake in Palau?
Snorkeling among the golden jellyfish has been one of Palau's signature experiences, and their sting is not felt by people — but the lake is fragile, has been closed to visitors at times so the population could recover, and its rules are locally managed. Verify what is currently allowed with a local operator or the park office before you plan around it.
Is Blue Corner a snorkel site?
No — Blue Corner and Palau's other celebrated walls sit at diving depth with serious current, and this catalog does not present them as snorkel sites. The snorkeling in Palau is the sheltered Rock Islands bays, the shallow patch reefs such as Clam City, and the channel edges at German Channel on the right tide with an operator who reads the flow.

Local food gems

Eat like a local — three off-the-radar spots to round out a day in the water. Spots above the tourist strip, found by asking where the boat crews and neighbours actually eat.

01

A Koror lunch counter doing Palauan tinola

Koror

Tinola is a Palauan staple — a soup of local taro, papaya and fish (sometimes chicken) — and it turns up on lunch menus in town alongside rice and the day's catch. It is home food, not a visitor's dish, which is exactly why it is worth ordering.

Tip: Order what the counter is serving that day rather than from a long printed menu; the daily dishes are the local ones.

02

Kangkum with garlic, the standard local side

Koror and Babeldaob

Kangkum — water spinach — was adopted from Asia and made local, stir-fried fast with garlic and served alongside grilled fish. It is the everyday green of Palauan cooking and rarely missing from a local table.

Tip: Ask for it local-style, with fish, rice and soy rather than as a garnish on a plate built for visitors.

03

Charcoal-grilled reef fish at the waterfront

Koror's waterfront and the local markets

Fresh reef fish grilled over charcoal is the everyday Palauan plate, and buying and eating it near the market in Koror is the honest way to have it — simple, local and nothing like a hotel buffet.

Tip: Ask what species you are being served: some reef fish carry ciguatera risk in this region, so take local advice on which fish to order and which to leave.
