Seen from the mainland, Hon Tam has the tapered shape of a resting silkworm — which is where the name comes from. The island sits inside Nha Trang Bay, roughly twenty minutes by boat from the city pier.
Its main beach is a gentle shelf of white sand, calm and shallow near the shore, which makes it forgiving for weak swimmers and children. Most of the island has been given over to tourism: a resort, seafood restaurants, parasailing, jet skis and mineral mud baths.
Hon Tam suits a slow day at the beach rather than an expedition. On a standard island-hopping tour it is the lunch and lounging stop in the middle of the day — paired with a morning of snorkelling at Hon Mun, it is the most common itinerary on the bay.
Because one operator runs the services, food and drink cost noticeably more than in town. Going independently, it is worth carrying water.
A note on tickets: island admission is often not included in a shared boat tour, and water activities like parasailing or jet skis are billed per go. Ask what is covered before you board so the extras don’t accumulate unexpectedly.
