Phuket's real advantage isn't just the island itself — it's everything within reach of it. A cluster of smaller islands, some reachable in under 20 minutes by speedboat, others a genuine day trip, gives Phuket-based travellers access to some of Thailand's best diving, snorkelling and limestone scenery without changing hotels.

Phi Phi Islands

Thailand's best-known island group, Phi Phi combines Koh Phi Phi Don (the inhabited main island, with Tonsai Village as its hub) with Koh Phi Phi Leh's dramatic cliffs and beaches, plus Bamboo Island's quieter white sand nearby. It's touristy for good reason — the scenery genuinely earns the reputation — so go early in the day if you want the beaches before the crowds arrive from Phuket and Krabi.

Koh Lanta

South of Phuket, Koh Lanta pairs excellent beaches with genuinely good diving close to shore — limestone outcrops rising out of the water, coral reef, and generally clearer conditions than some of the more built-up spots closer to Phuket itself.

Coral Island (Koh Hae)

About 15 minutes by speedboat from Phuket's southeast coast, Coral Island is the easiest of the group for a half-day trip — good snorkelling, two main beaches (Long Beach and Banana Beach) on its north side, and enough marine life close to shore to make it worthwhile even without committing to a full day.

Racha Islands (Koh Racha Yai and Koh Racha Noi)

About 20km south of Phuket, the Racha Islands split into two distinct experiences: Koh Racha Yai, the larger of the two, draws crowds for its white sand and resort development, particularly around the popular (and sometimes busy) Ao Tawan Tok beach; Koh Racha Noi is smaller, more rugged, and considerably quieter, better suited to travellers who want the diving without the resort crowd.

Koh Tachai

Roughly 135km northwest of Phuket, Koh Tachai (sometimes called Virgin Island) is further afield but rewards the trip — protected as part of the Similan marine park system, with a strong reputation among divers for encounters with nurse sharks and eagle rays alongside colourful reef fish. Access is seasonal and sometimes restricted to protect the reef, so it's worth checking current visitor rules before planning a trip specifically around it.

Coconut Island (Koh Maphrao)

Just 15 minutes off Phuket's east coast, Koh Maphrao is a low-key stop compared to the more famous islands nearby, but it works well as a jumping-off point for exploring Phang Nga Bay's smaller islets, including Koh Yao Noi and the Racha Islands.

James Bond Island

Khao Phing Kan's limestone karst formation, rising dramatically out of the sea in Phang Nga Bay, earned its nickname after featuring in the 1974 James Bond film The Man with the Golden Gun — about 90 minutes from Phuket by boat, and one of the more photographed rock formations in Thailand for good reason.

Koh Bon

A small, quiet island directly across from Rawai Beach, Koh Bon is a good choice if you want a slower day away from Phuket's busier stops — a long beach on its eastern side, a small sandy point at its northern tip, and decent snorkelling off its southwestern corner.

Further afield: the Similan Islands

For genuinely world-class diving further from Phuket, see our guide on Khao Lak and the Similan Islands — a longer trip than the islands above, but among the best diving in Thailand.

A few practical questions

How do I get to these islands from Phuket? Speedboat day trips are the standard option for most, typically booked through your resort or a local tour operator; some, like the Similan Islands and Koh Tachai, involve longer transfers.

When's the best time for island-hopping around Phuket? November to April, the dry season, offers calmer seas and better visibility for diving and snorkelling.

Are all these islands open year-round? No — some, including parts of the Similan marine park system, close seasonally (typically May to October) to protect the reef during monsoon season.
