Hong Island Lagoon
Krabi, Krabi, Thailand

The lagoon at the center of Hong Island, off Krabi, Thailand, is a hidden pool ringed by limestone cliffs, reached by kayak or on foot at low tide through a gap in the rock. The beach fronting the island has soft white sand and calm, shallow water, and it's one of the more sheltered stops on Krabi's island hopping circuit.
The lagoon itself is a genuine standout among Krabi's island stops, but it runs almost entirely on tour boat traffic, so solitude depends on timing a visit around the group schedules.
Go early or late in the day. Midday brings a steady rotation of speedboat tour groups, and the lagoon entrance can get congested with kayaks around lunchtime.
There's no independent access by car. Longtail boats and tour speedboats depart from the Ao Thalane pier or from Ao Nang, and most visitors come as part of a half day or full day tour.
The main beach is a flat, easy walk from where boats pull up, but reaching the inner lagoon means either a kayak paddle or wading through a rocky gap that's only passable at the right tide.
November through April is Krabi's dry season and the calmest window for the boat crossing and the lagoon paddle. The southwest monsoon from May through October brings rougher seas and more days where tours get cancelled.

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.
