Board a speedboat from Ao Nang and explore Hong Island’s 109‑meter viewpoint, mushroom‑shaped Pakbia rock, and the crescent sands of Lading before nightfall reveals bioluminescent plankton. This 6‑hour tour mixes snorkeling, short hikes, and a beach BBQ.
More ways to explore the area's outdoor wonders
A warm breeze hits your face as the speedboat slips away from Ao Nang’s shoreline and the first limestone fingers of Hong Island rise from the sea like old sculptures. You move through blue-green water toward a shallow, cliff-encircled lagoon where a treetop walkway climbs to a 109‑meter viewpoint — the island’s spine that rewards a short, steady climb with a full 360° sweep of neighboring isles.
