Long Beach is the quietest of the main beaches on Phi Phi Don, a 10-15 minute walk along the coast from Tonsai Village or a quick longtail ride. The absence of direct boat access from the pier keeps the crowds lighter than at Tonsai Beach itself, and the beach has a noticeably different atmosphere — calmer, less commercial, with the bars and restaurants spaced out rather than packed together.
The reef just offshore is worth snorkelling. There is good coral and the usual array of tropical reef fish, and the water tends to stay cleaner than around the village area. A handful of small guesthouses and restaurants operate on the beach itself. It is the sensible choice if you want a beach day without the full Phi Phi Don circus.
