Koh Hong
เกาะห้อง
A lagoon island in Tab Lan–Koh Hong National Park, ringed by cliffs like a 'room'. Features white-sand shallows, snorkelling and a 360-degree viewpoint reached by 419 steps.
Koh Hong ('Room Island') lies about 20 km northwest of Ao Nang, in the southern part of Phang Nga Bay, within Krabi's Tab Lan–Koh Hong National Park. It is a limestone island with a lagoon in its centre, enclosed by cliffs on all sides and connected to the open sea by a single narrow channel. Longtail boats can enter at high tide. The surrounding rock walls look like the walls of a room, and the lagoon's emerald-green water gave the island its name. Pelay Bay on the south side has fine white sand and a gently sloping shallow beach with very clear water. It is the main spot for swimming and snorkelling, and the place where tour groups stop for lunch. In 2019 the national park built a 419-step trail up to a 360-degree viewpoint overlooking the entire lagoon, the white-sand bay and the scattered rock islands in the sea, one of Krabi's most spectacular high sea views. The round trip takes about 40 minutes. Koh Hong trips are usually combined with nearby Koh Lading (Koh Pala), Koh Pakbia (the sandbar between two islands) and Koh Rai into a 'Koh Hong day trip'. Longtail boats cost about 1,200 to 1,500 baht per person and speedboats about 1,800 to 2,500 baht, with the 300-baht national park fee extra. A private longtail charter costs about 3,000 to 4,000 baht per boat. Compared with the Four Islands Tour, Koh Hong has clearer water and fewer people, and many consider it Krabi's most beautiful island. Travel tips: choose a tour departing at 9:00 am. Visit the viewpoint first while it is still cool, then swim and snorkel at Pelay Bay, and enter the lagoon in the afternoon. A longtail boat from Ao Nang pier takes about 45 minutes and a speedboat about 25 minutes. You can also leave from Ao Thalane in Krabi Town and combine the trip with mangrove kayaking. Notes: The lagoon is shallow, so boats cannot get in at low tide. The viewpoint steps are steep, so wear shoes and bring water. There are no shops on the island, so bring your own drinking water. The park clears the beach after 3:00 pm. Rough seas in the rainy season may cause cancellations.
