Phuket's greatest asset may be its position as a launchpad to some of the most beautiful islands and seascapes on earth. Within a boat ride you can reach the soaring cliffs and Maya Bay of Phi Phi, the surreal limestone karsts and hidden lagoons of Phang Nga Bay, the pristine reefs of the Similan Islands, the karst-and-beach coast of Krabi and Railay, and easy, family-friendly islands like Coral and the Rachas. Here are the six best excursions, with realistic travel times, prices, seasons and tips to make the most of a day on the water — most with hotel transfers included.

Day trips from Phuket in detail
1.Phi Phi Islands
A day trip to the Phi Phi Islands is on nearly every Phuket visitor's wish list, and for good reason — this small archipelago between Phuket and the Krabi mainland is among the most beautiful island groups on earth. Tours centre on two islands: Phi Phi Don, the larger, inhabited one with its distinctive dumbbell shape, twin curving bays and lively little village of bars, dive shops and restaurants; and uninhabited Phi Phi Leh, a dramatic block of soaring limestone cliffs that shelters the legendary Maya Bay, the perfect cove of white sand and jade water made famous by the Leonardo DiCaprio film The Beach. The scenery is simply spectacular — sheer green-clad cliffs plunging into water of an almost unreal turquoise, hidden lagoons like Pileh, sea caves, and coral reefs teeming with tropical fish that make for wonderful snorkelling, with stops usually including Monkey Beach and the Viking Cave. A typical day trip involves an early start and a fast, exhilarating speedboat ride out, taking in several snorkelling and swimming stops, the key sights and photo spots, and a beach or onboard lunch, before returning in the late afternoon. The islands' fame means they can get very busy, and Maya Bay in particular is now carefully managed with visitor limits and timed access after over-tourism forced its temporary closure and rehabilitation. To make the most of it, choose a tour that starts early to reach the highlights ahead of the peak crush, or pay a little more for a premium small-group option; some travellers even stay overnight on Phi Phi Don to enjoy the islands once the day boats have gone. However you do it, Phi Phi delivers the tropical-island dream in unforgettable style, and it is comfortably the most popular excursion from Phuket.

Insider tip: Book a speedboat tour that hits Maya Bay early; premium small-group trips are worth it to dodge the biggest crowds.
2.Phang Nga Bay & James Bond Island
Phang Nga Bay is one of the great natural wonders of Southeast Asia and, for many, the single most memorable day trip from Phuket. Sheltered between the island and the mainland to the north-east, this vast, calm bay is studded with hundreds of dramatic limestone karsts — sheer-sided towers and jungle-cloaked islets that erupt vertically from the shallow jade-green water, riddled with caves. The most famous is Koh Tapu, the slender rock pinnacle made globally famous as 'James Bond Island' by the 1974 film The Man with the Golden Gun, and it remains the headline photo stop on any tour. But the true magic of the bay lies in its hidden 'hongs' — collapsed cave systems forming secret tidal lagoons enclosed by cliffs, accessible only by sea canoe through low, dark tunnels that open into silent, emerald worlds of mangrove and birdsong, where a guide paddles you in to marvel at the hidden inner sanctuaries. Many tours also visit Koh Panyee, a fascinating Muslim fishing village built entirely on stilts over the water, complete with its own floating football pitch, where lunch is often served. Tours range from large motor-boat trips to far more rewarding small-group and sea-kayak excursions, and the latter, which get you into the caves and lagoons, are well worth the extra cost. The scenery is at its best in the softer light and calmer conditions of early morning, before the fleets of day boats converge. Whether you canoe the caves, swim in the lagoons, photograph James Bond Island or simply gaze up at the towering karsts, Phang Nga Bay is an unforgettable, bucket-list day and arguably the most scenically stunning trip on offer.

3.Similan Islands
The Similan Islands, a protected marine national park of eleven granite-and-jungle islands scattered in the Andaman Sea north-west of Phuket, are widely regarded as home to the most beautiful beaches and the best snorkelling and diving in all of Thailand, making a day trip here the top choice for nature lovers and underwater enthusiasts. Unlike the dramatic limestone karst scenery of Phang Nga and Phi Phi, the Similans are defined by their huge, smooth, rounded granite boulders, dazzling powder-white sand and water of extraordinary clarity — a pale, luminous turquoise over the shallow reefs that deepens to sapphire. Above the water, viewpoints such as Sail Rock on Island 8 reward a short scramble with a classic Thailand-postcard panorama over the islands and sea; below it lies a world-class underwater realm of vibrant hard and soft corals, swirling schools of colourful fish, sea turtles, reef sharks and rays that draws divers and snorkellers from across the globe. Because the park is strictly protected and exposed to rough monsoon seas, it is open only for the dry half of the year, roughly mid-October to mid-May, and closed entirely in the low season, so trips can only be taken in that window. A day trip involves an early start and a road transfer to a pier north of Phuket, followed by a fast speedboat ride out, making for a long day with plenty of travel, but for those who prioritise pristine nature, superb snorkelling and diving, and beautiful, unspoilt beaches over nightlife and shopping, the reward is well worth the effort. National-park fees apply on top of the tour price, and booking ahead is wise as the season and numbers are limited.
Hours
Park open mid-Oct to mid-May only (closed in monsoon)
Price
Day tours from ~฿2,500pp incl. transfers, lunch, snorkelling & park fees (~฿500)
Getting there
Speedboat (~1.5h) from Thap Lamu pier north of Phuket; tours include a road transfer from Phuket (~1.5h)
Insider tip: Open only mid-Oct to mid-May — the top pick for serious snorkellers and divers; expect an early start and a long day.
4.Krabi & Railay
The neighbouring province of Krabi, across the bay to the east of Phuket, boasts some of the most spectacular coastal scenery in Thailand, and while it is a destination in its own right, its highlights can be sampled on a long but rewarding day trip from Phuket. The star attractions are the dramatic limestone karsts that soar out of the sea and along the shore, the beautiful beaches, and above all the Railay peninsula — a stunning stretch of coast so hemmed in by towering cliffs that it is cut off from the mainland by land and reachable only by boat, giving it a magical, secluded island feel. Railay's gorgeous white-sand beaches, backed by sheer jungle-topped cliffs that are world-renowned for rock climbing, and its hidden lagoons and caves, make it a jaw-dropping spot to explore. The other classic Krabi experience is the hugely popular 'Four Islands' tour, a longtail or speedboat trip that takes in Phra Nang Cave Beach, Chicken Island, Tup Island and Poda Island, with excellent snorkelling, swimming and, at low tide, a magical sandbar that emerges to connect several islands so you can walk between them across the sea. Reaching Krabi from Phuket takes a couple of hours by a combination of road and boat, so organised day tours that handle the logistics are the easiest way to do it in a day, though the distance means an early start and a full day out. Given its beauty, many travellers choose to stay a night or two in Krabi or on Railay to explore properly. For a scenic, karst-and-beach-filled day showcasing a different, equally beautiful corner of the Andaman coast, a Krabi and Railay trip is a superb choice.

Insider tip: The Four Islands tour from Krabi and the cliff-backed Railay peninsula are the highlights — a scenic karst-and-beach day.
5.Coral Island (Koh Hae)
Coral Island, known in Thai as Koh Hae, is the closest of Phuket's satellite islands and the ideal choice for those wanting a quick, easy and relaxed taste of the Thai-island experience without committing to a long full-day boat expedition. Lying just a short fifteen-minute speedboat hop off the south coast near Chalong, it is superbly accessible, making it perfect for a half-day trip, for families with young children, or for anyone short on time. As its English name suggests, the island is fringed by coral reefs in clear, shallow, calm water, and its two main beaches — Long Beach and Banana Beach — offer good, accessible snorkelling straight off the soft sand, with plenty of colourful reef fish to see close to shore. Beyond snorkelling, the island is well set up for an active, fun day by the water, with a range of optional watersports on offer, including banana-boat rides, kayaking, parasailing and the popular novelty of 'sea walking' (helmet diving that lets non-swimmers walk on the seabed among the fish). Alternatively, you can simply hire a sun lounger, swim in the warm, gentle sea and relax on the beach, with beach restaurants and bars on hand for lunch and drinks. Because it is so close and accessible, the island can get busy around the middle of the day when the tour boats converge, so a half-day trip timed for the earlier morning or the later afternoon offers a more peaceful experience. Easy, inexpensive, close and family-friendly, a Coral Island trip is the perfect introduction to island-hopping and a great option when you want beach and snorkelling fun with minimal travel and fuss.

6.Racha Islands (Racha Yai & Racha Noi)
The Racha Islands (also spelled Raya) — comprising the larger, developed Racha Yai and the smaller, wilder Racha Noi — lie in the open sea south of Phuket, and they are celebrated for having some of the clearest, cleanest water and best snorkelling and diving conditions within easy reach of the island, offering a quieter and less crowded alternative to the famous but busy Phi Phi Islands. Racha Yai is the main focus of day trips, its picturesque bays fringed with beautiful white-sand beaches and startlingly clear, turquoise water that provides superb visibility for snorkelling right off the shore, where you can admire colourful coral and abundant tropical fish in calm, sheltered conditions ideal for all abilities, including beginners and families. The island's excellent water clarity and healthy reefs also make it one of the most popular destinations near Phuket for scuba diving and for those learning to dive, with several dive sites around both islands. Wilder, rockier Racha Noi to the south is less visited and geared more towards experienced divers, sometimes offering sightings of larger marine life such as manta rays. A typical day trip involves a roughly 45-minute speedboat ride from Chalong, with time for snorkelling at several spots, swimming, relaxing on the beach and a lunch stop, before returning in the afternoon; the calmer, drier season delivers the best conditions and visibility. Because the Rachas see fewer visitors than Phi Phi, they retain a more relaxed, natural feel while still delivering gorgeous beaches and outstanding underwater scenery. For snorkellers, divers and swimmers seeking beautiful, clear water and a slightly quieter island day, the Racha Islands are a superb and rewarding choice.
