Imagine heading out on an ordinary boat trip and finding the water alive with more than a thousand dolphins, a few blue whales surfacing among them. That is exactly what happened one nautical mile off Phu Quy Island, a small island district of Binh Thuan province in southern Vietnam, on the morning of October 6.
Local fisherman Huynh Ka, a coastal native who has spent his life on these waters, filmed the encounter and later said he had not seen a pod this size since he was a child. The animals were in the middle of their year-end seasonal migration, and their timing and numbers caught even seasoned mariners off guard.
The footage, quickly shared across Vietnamese social media, shows the dolphins riding alongside the hull, surfacing in waves and leaping clear of the water just metres from the boat. What has impressed viewers most is not only the headcount but how close the animals came — no long-distance specks on the horizon, but a full surround-sound wildlife moment with the pod practically escorting the vessel.
Phu Quy locals say visits from dolphins and whales are not unheard of, but they tend to happen toward the end of the year or in early spring, when the sea is calm and conditions are right. Even so, gatherings on this scale are rare. The buzz has already prompted talk of building responsible, low-impact dolphin- and whale-watching tours around the migration season — potentially giving the island a signature eco-tourism draw to complement its fishing-village charm, beaches and lighthouse.
Why should this be on your radar? Phu Quy remains one of Vietnam's quieter islands — far less developed than Phu Quoc, and reachable mainly by ferry or speedboat from Phan Thiet. If the migrations prove reliable, it could become one of Southeast Asia's more affordable whale- and dolphin-watching spots, especially if tours are run with proper respect for the animals: keeping distances sensible, limiting engine noise and avoiding crowding the pod. The alternative — a free-for-all of boats chasing dolphins — would be bad for the wildlife and, in time, bad for the island too.
For now, the advice is simple: if you're planning a southern Vietnam trip between late year and early spring, keep Phu Quy on the list. Calm seas, few crowds and, with a bit of luck, a boat ride you'll never forget.
