Ao Wong Dean

Ao Wong Deuan curves in a wide crescent along the east side of Koh Samet, and after Hat Sai Kaeo it’s the island’s second-busiest beach. Resorts, restaurants and beach bars line the sand, speedboats and ferries pull in through the day, and calm, clear water draws weekenders from Bangkok a few hours away. This is a lively, social beach rather than a hidden cove.

The bay is sheltered by rocky points at either end, which keeps the water calm and makes it an easy, gently sloping spot for wading and swimming rather than a snorkelling destination in its own right. Coconut palms shade a strip of the sand, small fishing boats pass the bay’s mouth, and the beach stays busy with boat traffic through the day rather than offering the quiet you’d get on Koh Samet’s smaller bays.

Ao Wong Deuan makes an easy base, with accommodation ranging from simple bungalows to mid-range resorts and plenty of places to eat and drink steps from the sand. Beach massage salas operate under the trees, vendors sell drinks and grilled seafood, and jet skis and banana boats run offshore. For more space, a footpath over the headland leads to the quieter neighbouring bays of Ao Thian (Candlelight Beach) and Ao Cho.

Insider Tip: If the crowds and boat noise aren’t what you came for, walk the headland path to Ao Thian in the early afternoon — it’s a 10-15 minute walk and a completely different pace once you’re over the rocks.

Early morning is the calmest, quietest stretch before day-trippers arrive on the late-morning boats. Koh Samet sits within Khao Laem Ya-Mu Ko Samet National Park, so a park entry fee applies — 200 THB for foreign visitors, 40 THB for Thai nationals — collected once on arrival at the island rather than per beach. Reach Ao Wong Deuan by ferry or speedboat from Ban Phe pier on the mainland; some boats run direct to the beach, otherwise it’s a short songthaew hop from the main pier at Na Dan. Bring sun protection and cash — there’s no bank or ATM on the beach itself.
