Điệp Sơn is a cluster of three small islands - Hòn Bịp, Hòn Giữa, and Hòn Đuốc - in Vân Phong Bay, Vạn Ninh district, northern Khánh Hòa, where a narrow sandbar emerges from the sea to connect the islands in a single walkable path. Estimates of its length and width vary quite a bit between sources - roughly 700 metres to a kilometre long, and anywhere from about 1 metre to several metres wide depending on the section and who's measuring - but the core experience is consistent: a strip of sand with open sea on both sides.
The Sandbar Walk
The sandbar has become one of Vietnam's most circulated travel images: a line of people walking across open water with turquoise sea on either side. The reality holds up in person, though the path's visibility depends on the lunar calendar rather than any fixed daily schedule - one local eco-tourism guide has noted that even at the highest tides the water over the path rarely rises above waist height, so it's less an all-or-nothing phenomenon than a matter of degree.
Setting and Overnight Options
The islands sit in a sheltered bay with clear water and minimal development, reached by boat from Vạn Giã port. The surrounding reef supports reasonable snorkeling, though it's worth being clear-eyed about overnight options: there are no real hotels or guesthouses on the island - staying over means bringing your own camping tent or renting one locally, and most visitors who want proper accommodation base themselves back in Nha Trang or Vạn Giã instead.
Điệp Sơn sits outside the Nha Trang tourist circuit and sees a fraction of the visitor numbers that comparable island destinations in Khánh Hòa attract - helped along by the fact that, as of recent reports, the island only has temporary tourism permission and falls outside the province's formal tourism development zoning.
