As one of the most striking rock formations, Hong Archipelago is a composition of 12 islets that vertically stretching from the North to the South of Krabi sea, near Phang Nga province. The islands are blessed by its shady silhouettes and Mother Nature’s charm, though they feature only a few reachable beaches and an overnight stay is not permitted. The highlight is a large lagoon embraced by surrounding mountains at the archipelago’s main island.
