The dormitory rooms look onto the garden and inner courtyard and include a fan and electric kettle.

Chalok Baan Kao is a quieter village on Koh Tao’s southern bay, with dive resorts, places to eat and a beach reached directly from the hotel. Chalok Baan Kao Beach is 50 m away, and Ao Chalok Ban Kao is 350 m from the property. Haad June Juea, another nearby beach, is 550 m away. The bay’s sheltered village setting contrasts with the livelier strip around Sairee on the island’s west coast.

Koh Tao has no airport, so you arrive by ferry at Mae Haad Pier. Lomprayah Koh Tao Pier is 1.9 km from the hotel; from Mae Haad, pickup-truck taxis connect the pier town with Chalok Baan Kao. Ferries link Koh Tao with Koh Samui, Koh Phangan and the mainland at Chumphon, although rough seas can disrupt crossings, particularly from November to January. Once in Chalok Baan Kao, the hotel’s beachfront position puts the bay’s sand beside the property.

For swimming and snorkelling, Freedom Beach is 650 m away and Shark Bay Beach is 700 m away. Sun Suwan Viewpoint, also 700 m away, looks across the southern coastline; John-Suwan Mountain Viewpoint is 900 m away, with views towards Ao Chalok and Ao Thian. The island has numerous dive sites, including Chumphon Pinnacle and Japanese Gardens. The south and west coasts are generally the calmer side from November to March, while whale sharks are most often seen around Koh Tao from March to May and September to October.
