Palau Spawning Expedition
Join a special departure with expert Richard Barnden aboard the S/Y Palau Siren to witness one of Palau’s mesmerising spawning events.
Palau's spawning aggregations occur within narrow lunar windows. Each departure is timed to a specific event and specific species, including moorish idols, twin spot snapper, sea bream, bumphead parrotfish and camouflage grouper.
Ten nights are spent aboard the S/Y Palau Siren, a traditional phinisi vessel built from ironwood and teak, diving up to four times a day, including the spawning events themselves. Reef and wreck diving between aggregations covers sites such as the German Channel, Ulong Island and Peleliu Island.

Nine Days Chasing Palau's Spawning Aggregations & Diving its Reefs & Wrecks
Early mornings or late evenings, depending on the species in season, are spent seeking out the aggregations under expert guidance. Moorish idols and twin spot (or bohar) snapper spawn around the full moon; sea bream, bumphead parrotfish and camouflage grouper spawn around the new moon.
Aggregations can run to many thousands of fish and draw in grey reef sharks, lemon sharks, oceanic blacktips and bull sharks. Where an itinerary covers two species, a few days are typically spent on each.
Daily diving beyond the aggregations covers Palau's celebrated reefs and wrecks, at sites such as Malakal Harbour, Ulong Island, German Channel, Ngemelis Island and Peleliu Island, with white-tip and grey reef sharks, manta rays and dense coral cover among the regular sightings.
