Lonely Beach
Koh Rong, Sihanoukville, Cambodia

Lonely Beach sits at the very northern tip of Koh Rong, Cambodia, deliberately far from the party scene that built the island's reputation on its southern end. A single small resort of solar powered bungalows sits above the sand, and after dark the water glows faintly with bioluminescent plankton when the surf or a swimmer disturbs it.
About as isolated and quiet as a Cambodian beach gets, with a genuine natural light show after dark, but the total lack of amenities and cash-only setup mean it takes real commitment to get to and stay at.
Bring enough cash for your whole stay. There's no ATM anywhere near Lonely Beach, and it's a private boat transfer just to reach it, so running short isn't a quick fix.
There's no walk-in or public boat access. Getting to Lonely Beach means arranging a private transfer from Koh Touch or Sihanoukville, usually booked through the resort itself.
Boats land directly on the sand, and there's no paved path or facilities beyond the resort's own bungalows, which sit just above the beach.
The dry season from November through April brings the calmest seas for the boat transfer and the best visibility for the bioluminescent plankton at night. The wet season from May through October brings rougher crossings and less predictable conditions.

Sanom Beach
Koh Lipe, Satun, Thailand · Asia Pacific
Sanom Beach sits at the far southern end of Pattaya Beach on Koh Lipe, Thailand, reached by a wooden walkway over the rocks once the main beach runs out. The sand is quiet compared to Lipe's busier strips, backed by shade trees, and the resort here is run by local Urak Lawoi sea gypsies rather than an outside chain.
Bamboo Bay
Koh Lanta, Krabi, Thailand · Asia Pacific
Bamboo Bay, also called Ao Mai Phai, is the last beach before Koh Lanta's national park boundary, a two kilometer curve of sand at the island's southern tip in Krabi province, Thailand. Big boulders break up the shoreline in places, the water stays clear enough to see your feet, and by evening the day trippers have mostly cleared out.

Sunset Beach
Koh Kradan, Trang, Thailand · Asia Pacific
Sunset Beach is the quieter western shore of Koh Kradan in Trang province, Thailand, a short walk across the island from the long main beach that gets most of the attention. There's less wave action here than on the east side, the swimming stays calmer, and as the name promises it's the spot locals and the handful of resort guests head to for the evening light.
