Ya Nui and Nui Beach sit near Promthep Cape at the island's southern tip — two small coves known for calm, clear water.
Ya Nui
A compact, sheltered beach popular for snorkelling directly offshore, with a small reef reachable without a boat — one of the more accessible snorkel spots on the island for that reason. See our water activities guide for how it compares to boat-based snorkelling trips.
Nui Beach
Smaller still and less developed, reached via a short, sometimes steep access road — quieter than Ya Nui as a result, and often nearly empty outside weekends.
What to bring
Neither beach has significant facilities beyond a few small vendors — bringing your own snorkel gear, water and sun protection is worth it rather than assuming rental will be readily available on-site.
Why visit
Both sit close enough to Promthep Cape and Rawai to combine into a single half-day loop covering sunset, snorkelling and a seafood dinner without much driving between stops.
