The Yacht & Comfort Onboard

From the moment we started reading about this tour, the standout feature was the luxurious yachts, Blue Dragon and Red Dragon. Designed specifically for comfort and adventure, these boats are not your standard day-trip vessels. With a spacious sun deck, plenty of shaded lounging areas, and a fully furnished lounge and dining space, you’ll have many spots to unwind amidst the action. Reviewers consistently mention the ample space—a relief when compared to cramped speedboats—and the relaxing environment they provide.

The jacuzzi aboard the yachts is a hit, especially after a morning of kayaking or hiking. It offers an opportunity to cool off, soak in the sun, and take in the panoramic views. The boat’s design emphasizes European boating standards, combined with Thai hospitality, creating a safe, comfortable, and welcoming atmosphere.

The Itinerary and Activities

Morning Departure & the Cruise to Ang Thong

The day kicks off with a delicious breakfast as you cruise toward the northern part of the marine park. The first leg involves a scenic sailing time of about 2.5 hours, during which you can enjoy the company of your small group and admire the spectacular sea views. One reviewer noted, “the boat was comfortable, and sailing time was a good chance to relax and enjoy the scenery.”

Visiting Hidden Gems with Kayaking and Snorkeling

Once at the park, the real fun begins. The exclusive itinerary takes you to spots that most travelers don’t get to see, thanks to the semi-private approach. Activities include kayaking around limestone islands, exploring caves, tunnels, and the secret lagoon—a truly magical experience because you’re paddling in areas rarely visited by larger groups.

Reviewers often mention that kayaking was a highlight, with one saying, “the guides took us through cliffs and small lagoons, and it was excellent.” The sea kayaking option is optional but highly recommended for those who want an active adventure. As one guest noted, it requires some steering skill, but the guides are there to help.

For non-swimmers or those who prefer a relaxed experience, the Aquaglide Lounge allows you to float above the reef, enjoying the vibrant marine life without getting wet—another thoughtful touch appreciated by many.

Climbing to the Emerald Lagoon Viewpoint

One of the most memorable moments is the hike to the Emerald Lagoon viewpoint. The trail involves narrow ravines and steps, but the view is well worth the effort.
