Reviews Summary
Visitors rave about the stunning, hidden beauty of Hong Lagoon, often describing it as a magical 'room in the sea' surrounded by dramatic cliffs. The unique experience of entering through a narrow passage and swimming in the calm, emerald waters is a major highlight.

"Hong lagoon is a part of the Ko Hong island with a shallow water lagoon.
The entrance to the lagoon is narrow, can only be reached by long tail boats/speed boats. Cannot be sailed by catamarans or cruises.
Hong in Thai means room - so this lagoon resembles a room to the local fishermen. It is said that the local fisher men use this lagoon to safeguard themselves from the rough waves of the outside sea. The lagoon is always calm and they sail into the lagoon to sleep during the night, hence the name Hong resembling to a room in the sea.
The water is around a depth of 1.5 metres but very milky so not suitable for snorkeling, you can have a good swim at best."
