A Private Day on the Water: Exploring Ko Lanta’s 4 Islands by Longtail Boat
If you’re seeking a flexible, personalized adventure to see some of the most beautiful spots around Ko Lanta, this private longtail boat tour might just fit the bill. For around $220 per group, you get to visit Koh Mah, Koh Chuak, Koh Ngai, and Koh Mook, with plenty of time to explore at your own pace. The tour lasts about 7 hours, with the convenience of hotel pickup and drop-off included, making it ideal for families or friends who prefer a relaxed, tailored experience away from overcrowded tours.
What we love most about this trip is how unrestricted it feels—you’re in control of your schedule and destinations, unlike many group tours that rush through highlights. The chance to swim into the Emerald Cave—a true hidden gem—is a highlight, and snorkeling with marine life in coral reefs provides memorable underwater moments. The local guides, who seem committed and friendly, really add a personal touch, making the day both smooth and engaging.
That said, one thing to keep in mind is the weather dependency of the trip—windy or stormy days can lead to cancellations or less enjoyable conditions, as some reviews have noted. Also, a national park fee of 200 THB per adult is payable on-site, so factor that into your budget.
This tour is perfect for those who value flexibility, authentic scenery, and a quieter experience compared to crowded speedboat trips. If you’re comfortable with some physical activity, like swimming or snorkeling, and want to avoid large crowds, this private excursion offers a great balance of adventure and comfort.

The Itinerary: A Closer Look
Stop 1: Koh Ngai (1 hour)
Your journey begins with a visit to Koh Ngai, a small but stunning island. Expect crystal-clear waters perfect for a quick dip or snorkeling. Its white-sand beaches are ideal for lounging and soaking up the sun, while the surrounding jungle offers a peek at local wildlife. One review notes, “The snorkeling was fantastic, and the beach was peaceful—much better than the crowded beaches you see elsewhere.”
While only an hour is allocated here, it’s enough to appreciate the tranquility and natural beauty of this spot. Since there’s no entrance fee, the focus is on enjoying the scenery.
Stop 2: Koh Mook (1 hour)
Next, you’ll head to Koh Mook, known for its low-key beaches and the famous Emerald Cave (Morakot Cave). Here, you can relax on the quiet beaches or prepare for the highlight: swimming into the limestone tunnel that leads to a hidden lagoon and sandy beach inside the cave.
One traveler said, “The cave is a bit scary but absolutely worth it. Swimming through the underwater tunnel was an adventure I won’t forget.” The tour includes admission to the cave—a key experience for anyone eager to see one of Thailand’s unseen attractions.
Stop 3: Morakot (Emerald) Cave (2 hours)
The main attraction of this tour is the Emerald Cave, which requires swimming through an 80-meter underwater tunnel. Inside lies a secret lagoon with a pristine sandy beach, surrounded by towering limestone cliffs. The experience is physically demanding but incredibly rewarding, offering a true sense of adventure.
Guests should be comfortable swimming and prepared for some water activity, but guides are usually helpful and supportive. As one reviewer put it, “The cave is a bit scary, but the view inside is surreal. It’s a rare chance to see such a hidden paradise in Thailand.”
Stop 4: Koh Chuak and Final Relaxation
The last stop varies depending on the group’s interests, but many use this time for snorkeling, relaxing on beaches, or enjoying a Thai lunch with seasonal fruits. The included lunch offers a taste of local cuisine with scenic views, making the meal a highlight after a morning of activity.
What You’ll Love About This Tour

Considerations and Potential Drawbacks
While the tour offers great flexibility, weather can interfere—some reviews mention cancellations due to wind or bad weather, which is common with outdoor water activities. The national park fee of 200 THB per adult isn’t included in the price, so budget accordingly.
Some travelers have noted gear issues—specifically, snorkel masks not being available at times—so it’s worth checking in advance. Also, those with health issues or who are pregnant might want to reconsider, as swimming into the cave requires some physical effort.
