Tung Thu Beach
Cat Ba Island, Hai Phong, Vietnam

Tung Thu Beach faces Lan Ha Bay from the edge of Cat Ba Island, Vietnam, a crescent of golden sand about 2 kilometers from Cat Ba Town, quieter than the beaches right in town. Limestone islands dot the bay in the distance, and it's become a favorite spot locally for sunset more than for swimming laps.
A pleasant, easy bay view with real facilities on hand, but it's more of a scenic sunset stop than a serious swimming beach, and it can't match the drama of the more remote Lan Ha Bay coves.
Come for sunset rather than midday. The light over Lan Ha Bay's karst islands is the real draw, and the crowd thins out noticeably once the tour boats head back to the harbor.
It's an easy 2 kilometer ride from Cat Ba Town by motorbike, taxi, or on foot along the coastal road, with informal parking near the beach entrance.
The beach has a maintained, easy walk-in from the road, flat and manageable for most visitors, with restrooms and changing rooms on site for a small fee.
Warm water and the calmest bay conditions run from May through October, while the cooler winter months bring fog that can dull the karst island views the beach is known for.

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.
