1. Why Visit Diep Son Island & Van Phong Bay
- Untamed turquoise lagoon ringed by talcum-fine dunes and a 700 m sandbar you can literally walk across at low tide.
- Chill fishing-village vibes—no high-rise hotels, just coconut palms and wooden boats.
- Only-here experiences: sunrise sand-sledding on rolling dunes, SUP inside a hidden lagoon, and lunch at floating lobster farms.
2. History, Legends & Cultural Significance
Long before today’s snorkellers, Cham sailors sheltered in Van Phong’s deep natural harbour. Local lore speaks of Nữ Oa—a mermaid who raised the sandbar so fishermen could walk home even when storms stranded their boats. Rock arches on Hon Lon are called “Dragon Gates” believed to guard the bay’s prosperity. Conservationists declared the surrounding mangroves part of Khanh Hoa’s proposed marine protected area in 2024.
