Phuket: Similan Island Day Trip by Speed Boat Catamaran

Exploring the Similan Islands on a Speed Boat Catamaran from Phuket

Taking a day trip to the Similan Islands is a classic way to experience some of Thailand’s most breathtaking marine scenery. While we haven’t personally done this exact tour, reviews and detailed itineraries give us a good picture of what to expect. The journey promises a mix of snorkeling, island exploration, and relaxing on powdery white beaches—all in a single 11-hour adventure.

What we love about this type of trip is the chance to see Thailand’s underwater world, enjoy pristine beaches, and escape the crowded mainland. The luxury speed boat, scenic stops at multiple islands, and the opportunity to snorkel among colorful corals are major highlights. That said, it’s worth noting that the experience can get crowded—around 60 people on the boat—so it’s not the most intimate escape.

This tour tends to suit travelers who love outdoor adventures, marine life, and scenic views, but prefer a full-day organized activity that covers a lot of ground. It’s an excellent choice for those wanting a balance of adventure, comfort, and stunning scenery—especially if you’re short on time but craving a taste of the islands’ beauty.

A Detailed Look at the Similan Island Trip

The Departure and Transportation Experience

The tour begins with a pick-up from your Phuket hotel—a convenient start that saves you from the hassle of organizing transport. The journey to the pier takes about 2 hours via van, giving you time to relax or soak in the scenery. Once at Thap Lamu Pier, expect a 30-minute welcome with refreshments like juice, coffee, and bread, setting a casual, friendly tone for the day.

From there, you board a luxury catamaran, which takes approximately 1.5 hours to reach the islands. While the vessel is described as a “luxury” catamaran, some reviews note that it can be quite crowded, with around 60 people onboard, which can influence the overall intimacy of the experience. Still, the spacious deck offers good vantage points to enjoy the sea breeze and views.

Snorkeling at Koh 5 and Koh 4 (Koh Miang)

The first stop at Koh 5 is a perfect introduction to the underwater world. The snorkeling here is in clear, blue water with soft coral reefs, making it a favorite among guests. Expect to see lively fish and colorful coral. One reviewer mentioned that the boat stops at a “single rock boat,” resembling a whale, which provides a unique photo opportunity. Snorkeling stops typically last around 35 minutes, giving enough time to get comfortable in the water and snap some photos.

Next, heading to Koh 4 (Koh Miang), you’ll find two gorgeous beaches, ideal for swimming, relaxing, or strolling. There’s also a viewpoint that offers sweeping vistas of the islands and ocean, perfect for photos. Guests have appreciated the chance to explore the island, walk along the beaches, and enjoy the scenery.

Lunch and Beach Relaxation

After a busy morning of snorkeling, the tour provides a boxed lunch on Koh Miang, usually including Thai-style dishes like fried chicken and papaya salad. This is a good opportunity to refuel and enjoy the scenic surroundings. Many reviews highlight the importance of bringing a change of clothes, as you’ll likely want to relax on the beach afterward—walking, taking pictures, or simply soaking up the sun.

Exploring Koh Bangu and the Underwater Marvels

Post-lunch, the boat heads to Koh Ba Ngu (Island 9), famed for its stunning coral formations and abundant marine life. This stop is ideal for more snorkeling and underwater photos, with visibility often praised by previous travelers. The vibrant underwater world here really lives up to its reputation, with lively fish and colorful coral creating a kaleidoscope effect beneath the surface.

Sailboat Rock and the Final Beach Stop

The last significant stop is at Sailboat Rock on the Similan Islands, where you’ll have about 80 minutes to walk, swim, and take in the views. The rock formations here are particularly striking, and from the top of Sailboat Rock, you’ll get a panoramic view of the island and surrounding sea. It’s a favorite part of the trip for photographers and nature lovers alike.

The tour concludes with a visit to Goer Bay (Donald Duck Bay), famous for its oddly shaped rocks and powder-soft white sand beaches. Relaxing here is a highlight, with many guests noting how fine and clean the sand feels and how clear the water is—perfect for wading or just lying back with a good book.

Return Journey and Refreshments

After a full day of activities, you’ll head back to Thap Lamu Pier, where the boat offers refreshing drinks, snacks, and local dishes like ice cream and Thai favorites. The return trip takes another 1.5 hours, giving you time to unwind and reflect on the day.

What You Need to Know

The overall schedule is tightly packed, with about 2 hours each way in the van, 1.5 hours on the boat each leg, and roughly 3-4 hours of island time. This structure allows for maximum island exploration but leaves little room for extended relaxing or non-stop activity.

Tour guides and staff— available in English, Thai, Chinese, and German—are described as friendly and helpful. However, given the size of the group, some travelers have noted that the experience can feel rushed.

Pricing and Value

The tour includes all transportation, meals, snacks, and park fees (which are 500 THB per adult and 300 THB per child). While the overall cost might seem steep, considering the included meals, boat transfers, and multiple snorkeling stops, many find it offers good value for a full-day adventure in a stunning setting.

Authentic insights from reviews

Reviewers have highlighted that the organization runs smoothly despite the large group, and the scenic views are truly impressive. One traveler remarked, “the circuit is very well organized, which prevents everyone from crowding at the same spots,” a key factor in making the day enjoyable. Another shared, “the staff on the boat was very friendly, and the islands are simply wonderful,” confirming the overall positive vibe of the trip.

Who Is This Tour Best For?

This trip is ideal for adventurous travelers who love outdoor activities and are eager to see Thailand’s marine life up close. It’s suited for those comfortable with boat travel and snorkeling, although not recommended for pregnant women or individuals with certain health issues.

If you’re looking for a luxurious, intimate experience, the crowded boat might be a drawback. Conversely, if you value seeing multiple islands and snorkeling spots in one day, this tour offers excellent coverage. It’s especially good for first-timers wanting a comprehensive snapshot of the Similan Islands’ beauty without the hassle of planning logistics.
