Koh Lanta: 4 Islands Tour by Speedboat with Snorkeling

Imagine spending a full day exploring some of the most beautiful spots in the Andaman Sea—Koh Mook, Koh Kradan, Koh Ngai, and Koh Chuak—all from the comfort of a speedboat. For around $49 per person, you’ll get approximately eight hours of island hopping, snorkeling, and relaxing, with a convenient hotel pickup in Koh Lanta. The tour offers a chance to see pristine beaches, swim through caves, and snorkel in vibrant coral reefs—perfect for those who crave authentic tropical experiences without the hassle of planning every detail.
What we really appreciate about this tour is the opportunity to visit both well-known highlights like the Emerald Cave and lesser-crowded snorkeling spots. Plus, the buffet lunch on Koh Kradan provides a restful break amid stunning surroundings. However, it’s worth noting that the tour can feel quite busy and touristy, especially in peak times, and the group size can grow larger than expected. Still, if you’re eager for a full day of island adventures with a knowledgeable guide, this trip fits the bill.
This experience works well for travelers who don’t mind sharing the boat with a larger group and are comfortable with a fast-paced itinerary. It’s especially suitable for those wanting to tick off multiple islands in one day, with plenty of swimming, snorkeling, and relaxing on beautiful beaches. Be prepared for some crowds if visiting during peak season, but expect incredible scenery and a good dose of adventure.

An In-Depth Look at the Tour Experience

The day begins with a hotel pickup in Koh Lanta, which is a real advantage, saving you the hassle of finding a meeting point early in the morning. Your guide will likely introduce the day’s schedule and give a quick safety briefing, all in English. Then, aboard a speedboat, you’ll set off across the calm waters of the Andaman Sea, heading toward your first destination: Koh Chuak.
Koh Chuak: Snorkeling and Coral Reefs
Koh Chuak is renowned for its lively coral reefs. As we loved, the reefs here are vibrant, teeming with colorful fish and marine life, making it an excellent spot for snorkeling. The snorkeling equipment is included, and the shallow waters are safe for swimmers of all levels. Expect to spend around an hour here, floating above the coral and getting your first taste of the underwater world. The reviews mention that some spots, like Koh Chuak, can be crowded with snorkelers wearing bulky life jackets, which can detract from the experience. However, with patience, you’ll still enjoy the stunning views beneath the surface.
Koh Mook and the Emerald Cave: A Natural Wonder
Next, you’ll arrive at Koh Mook, home to the famous Emerald Cave—a real highlight of the tour. Access to the cave is only possible during low tide, so timing is crucial. We loved the thrill of swimming through the narrow, 80-meter-long tunnel into a hidden lagoon surrounded by towering cliffs. The sunlight reflecting through the water creates that iconic emerald glow, which makes for fantastic photos. Inside, there’s a small sandy beach perfect for relaxing and marveling at the natural beauty.
One reviewer, Michael, said, “The islands were very beautiful and the beaches were fantastic,” though he also noted that the tour felt somewhat crowded and only lasted about seven hours, which is a typical concern for those hoping for a more relaxed experience. Still, the Emerald Cave is a genuine spectacle worth the effort.

The tour then moves to Koh Kradan for a buffet lunch on the beach. You’ll love the laid-back vibe here, with plenty of free time to swim, sunbathe, or explore. The beach is often praised for its soft sand and clear waters, perfect for relaxing after the morning’s excursions. Many travelers appreciate the comfort of a well-organized meal in such a beautiful setting.
Following lunch, you’ll have the opportunity to snorkel around Koh Kradan’s reefs or simply unwind on the pristine beaches. The coral reefs here are vibrant, and we’re told it’s a good spot for both beginners and experienced snorkelers.

Koh Ngai: Final Stop for Swimming and Snorkeling
The last island on the itinerary is Koh Ngai, where you can enjoy swimming and snorkeling along the shoreline. It’s a scenic way to finish the day, with calm waters and plentiful marine life. After some water fun, you’ll board the boat back to Koh Lanta, typically arriving later in the afternoon. The return journey offers a chance to reflect on a full day of island hopping, scenic views, and underwater exploration.
Transportation, Group Size, and Value

The speedboat transfer is quick and efficient, cutting down travel time between islands and allowing more time for activities. Since the tour is limited to small groups, guided by an English-speaking guide, you’ll get more personalized attention—though the actual group size can sometimes be larger than expected, as some reviews indicate.
At $49 per person, the price is reasonable considering the number of islands visited, the included snorkeling gear, buffet lunch, fruits, drinks, and the hotel pickup service. The cost of national park fees (200 THB for adults, 100 THB for children) is an extra you’ll need to budget for and pay locally.
What to Expect and What to Bring
We recommend bringing a towel, sunscreen, and waterproof bag for your belongings. The tour isn’t suitable for non-swimmers or those with back problems, and you should be comfortable in water for snorkeling and swimming. The boat ride, while exciting, can be bumpy at times, especially if weather conditions change.
Weather and Cave Access
Keep in mind that weather conditions can affect the tour, including access to the Emerald Cave. If the tide isn’t low enough or if storms threaten, parts of the trip might be canceled or rescheduled, so booking with flexibility is wise.
Authenticity and Practicality

While the tour offers a great overview of the region’s famous sights, some travelers find it a bit touristy, especially in peak season when the reefs and beaches can be crowded. One reviewer expressed disappointment, noting that many snorkeling spots were filled with snorkelers in bulky gear, which might diminish the sense of natural tranquility. It’s worth considering if you’re seeking a quieter, more secluded experience or if you’re happy sharing the water with fellow travelers.
However, the knowledgeable guide and well-organized itinerary ensure you’ll see some of the most iconic and beautiful spots in the area, making it a good value for those pressed for time or new to the islands.
Who This Tour Is Best For

This trip suits travelers who want a full day of island adventures with minimal planning. It’s ideal for those eager to see multiple islands, snorkel in colorful reefs, and visit the Emerald Cave. If you’re comfortable with large groups and crowded snorkeling spots, you’ll find this tour quite rewarding. It’s less suited for travelers seeking serene, off-the-beaten-path experiences or those with specific physical limitations.
Final Thoughts

The Koh Lanta: 4 Islands Tour by Speedboat offers a balanced mix of adventure, relaxation, and natural beauty. It’s a practical way to see some of the best spots in the Andaman Sea without the hassle of organizing multiple transports or tours. Expect spectacular views, lively reefs, and memorable moments exploring caves and beaches.
For travelers eager to pack in as much as possible in a day and enjoy guided insights from friendly, knowledgeable guides, this tour delivers solid value. Just remember, the crowds can be thick during peak times, and some spots might feel overrun. If you’re okay with that, you’ll leave with plenty of photos and stories from four of Thailand’s stunning islands.
