AT A GLANCE
Why go?
Off the coast of Palau's main town, Koror, Fantasy Snorkel draws visitors to a snorkeling spot that earns its name in the most literal way possible. Just offshore from one of the Rock Islands, a field of blue coral stretches across the shallows in a shade so vivid it tints the surrounding water an otherworldly blue-green. Most coral looks brown, tan, or muted in tones — this is genuinely, strikingly blue, the kind of underwater color that makes you check whether your mask is distorting things.↗
Set within the UNESCO-listed Rock Islands Southern Lagoon, Fantasy Snorkel sits in a marine environment where limestone mushroom-shaped islets rise from turquoise water and the reef life around them thrives in remarkable clarity. For a snorkeler arriving from anywhere else, the combination of that rare blue coral and the surreal island backdrop makes this a stop worth building a day tour around.↗↗
What Makes the Blue Coral Special
The coral field at Fantasy Snorkel is not the usual brownish hard coral you find on tropical reefs. Travelers who snorkel here describe an actual blue coloration that is unusual enough to be the island's calling card. In clear, shallow water over white sand, blue coral can appear even more vivid, giving the whole area a glow that photographers chase. Beyond the color, the shallowness means you do not need to be a strong swimmer or wear fins to get a good look — you can simply float face-down and watch the formations beneath you.↗
The Rock Islands Backdrop
Fantasy Island is one of roughly 445 limestone islets in Palau's Southern Lagoon, a UNESCO World Heritage Site inscribed in 2012 for both its natural beauty and ecological significance. The islands get their mushroom shapes from bio-erosion at the waterline, where urchins, sponges, and wave action hollow the bases over centuries while forest canopy remains intact above. When you are snorkeling at Fantasy Snorkel, you are floating through this seascape — green domes overhead, clear water below, and the quiet of a lagoon far from open-ocean swell. The island itself has a beach where you can pull yourself ashore and explore on foot after your time in the water.↗↗
The broader lagoon contains over 50 marine lakes, hundreds of coral species, and reef systems with schools of tropical fish. Even if the blue coral field is your reason to come, the surrounding waters reward the extra minutes you spend looking around you.↗

A little planning goes a long way
- A Rock Islands permit (approximately US$100 per person, valid about 5–10 days) is required before entering the Southern Lagoon. Fees fund conservation patrols and research. Confirm current pricing and validity directly with a tour operator or Koror State authorities before booking.↗
- Fantasy Snorkel is accessed by boat from Koror, typically as part of a multi-stop Rock Islands day tour. Most operators combine it with other highlights like the Milky Way mud flats, hidden lagoons, and mangrove channels.↗↗
- Use reef-safe sunscreen only, applied before you arrive on the water. Palau's environmental laws and permit conditions restrict standard sunscreen chemicals to protect delicate reef ecosystems.↗↗
- Best time to visit aligns with Palau's dry season, November through April, when seas are calmer and lagoon visibility is highest. October to early November offers a shoulder-season balance of good conditions and fewer crowds.↗
- Bring a mask and snorkel if you are joining an independent trip; operators provide gear on guided tours. Consider a camera or GoPro — the blue coral reads far more vividly on film than in memory.
