Must-do Sea Activities & Tours in Phuket

5 Must-Do Sea Activities in Phuket

Phuket, one of Thailand’s most popular island destinations, attracts millions of visitors every year thanks to its stunning natural beauty. White sandy beaches, crystal-clear turquoise waters, world-class diving spots, islands made famous by movies, vibrant marine life, and unique natural formations make Phuket a true paradise—especially for sea and nature lovers.

For most travelers, the main reason to visit Phuket is to:

• explore famous islands,

• swim in pristine waters,

• experience snorkeling and diving,

• discover breathtaking coastal landscapes,

• and enjoy unforgettable sea adventures.

In this article, we’ve carefully selected and detailed the 5 most popular and must-experience sea activities in Phuket. Although the island offers dozens of different tours and excursions, this list is especially helpful for first-time visitors who want to make the most of their time in Phuket.

1️⃣ Phi Phi Islands Tour

The Phi Phi Islands Tour is by far the most popular sea excursion in Phuket. There are many different versions of this tour, using speedboats or catamarans, and offering slightly different itineraries.

The typical route includes visits to at least 4 different islands and stops at 6–7 scenic locations throughout the day. Most Phi Phi tours operate on an all-inclusive basis, which usually covers: hotel transfers, lunch, professional guide, snorkeling equipment.

The highlight of the tour is Maya Bay, the iconic beach where Leonardo DiCaprio’s movie The Beach was filmed. During the day, guests can swim, snorkel, relax on beautiful beaches, and explore different islands. Visiting Phuket without joining a Phi Phi Islands tour is considered a missed opportunity by many travelers.

2️⃣ James Bond Island (Phang Nga Bay) Tour

The James Bond Island Tour is the second most demanded sea activity in Phuket. Unlike Phi Phi, this tour focuses more on sightseeing and exploration rather than swimming.

During the tour, you will:

• visit the famous James Bond Island,

• explore sea caves by canoe,

• see dramatic limestone rock formations,

• paddle through mangrove forests,

• visit floating fishing villages built on the water.

This is usually a full-day tour, and like most Phuket excursions, it is all-inclusive, covering lunch, hotel transfers, and entrance fees. One of the main attractions is the island featured in a James Bond movie, making it a perfect tour for photography and unique landscapes.

3️⃣ Similan Islands Tour

The Similan Islands are among the most pristine and breathtaking island groups in the Andaman Sea. What makes this tour truly special is that it is available only 6 months of the year. For the remaining 6 months, the islands are completely closed to tourism.

The reason is environmental protection: the Similan Islands are an important breeding area for sea turtles, including loggerhead turtles. To preserve marine life, access is strictly limited.

The Similan archipelago consists of 9 islands, but only 6 islands are open to visitors during the season. There is no accommodation or permanent settlement on the islands.

The tour is famous for:

• exceptionally clear water,

• colorful coral reefs,

• some of the best snorkeling and diving spots in Thailand.

Tours start very early in the morning because the pier is located in northern Phuket, and the islands are about two hours away by boat. Despite the long journey, Similan Island tours are in extremely high demand and are considered a must-see natural wonder.

4️⃣ Scuba Diving Tours

Phuket is not only about island hopping—it is also one of Thailand’s top destinations for scuba diving. The island offers unforgettable underwater experiences for both beginners and certified divers.

Available options include:

• Discover Scuba Diving programs for first-timers,

• advanced dives and wreck dives for licensed divers.

Diving tours can be:

• one-day or multi-day,

• tailored to your experience level,

• conducted on different dive routes.

Most diving tours include transportation, equipment, meals, and professional instructors. Phuket’s rich marine biodiversity, colorful corals, and tropical fish make it an excellent destination for underwater exploration.

5️⃣ Racha & Coral Islands Tours

The Racha and Coral Islands are among the closest islands to Phuket, making them ideal for half-day or full-day tours.

Unlike other island tours, these trips focus less on visiting multiple locations and more on:

• relaxing on beautiful beaches,

• swimming in calm waters,

• enjoying a peaceful day away from crowds.

Most Racha & Coral Island tours are operated by catamaran, offering a comfortable and smooth ride. These tours are perfect for travelers who want a relaxing beach experience on white sand beaches without spending a full day traveling long distances.
