This full-day tour, organized by BB Divers, promises a safe, well-paced experience that caters to a range of skill levels—whether you’re a seasoned scuba enthusiast, a freediver, or just eager to snorkel in crystal-clear waters.
What we love most about this trip is how it carefully balances adventure with comfort—you get the chance to explore wrecks and reefs on a spacious boat, all while enjoying delicious Thai-style lunches and drinks.

What Makes This Tour Stand Out

When considering a day trip like this, the main draw is the balance of adventure, safety, and value. The tour’s emphasis on small group numbers—limited to four participants—means you’ll get more personalized guidance, which is especially reassuring for newer divers or families. The full equipment included means you won’t need to worry about lugging gear or renting from questionable sources. You can simply focus on enjoying the experience.
The boat itself is described as spacious and comfortable, perfect for relaxing between dives or snorkeling sessions. Sunbathing on deck while sipping a cold drink is often mentioned as a highlight, especially after a morning underwater.

Itinerary Breakdown: What You Can Expect

Morning Pickup and Transfer
The tour begins early with hotel pickups on the west coast of Koh Chang, which saves you from the hassle of organizing transport. Being picked up from your hotel sets a relaxed tone for the day. The journey to the boat is smooth, and you’ll be briefed on safety and what to expect at each site.
First Stop: HTMS Chang Wreck
This is the highlight for many. The HTMS Chang is a shipwreck that’s become an artificial reef teeming with marine life. It offers a fascinating mix of exploration and marine photography opportunities, especially for those interested in wreck snorkeling or scuba.
Reviewers note that the tours are well-organized, with guides providing a thorough safety briefing beforehand. One reviewer from Switzerland remarked, “The diving environment was one of the most beautiful we explored in Thailand.” Such feedback indicates the wreck’s appeal is genuine and well-maintained, making it suitable even for less experienced divers.

One traveler from France called the guides “very professional and attentive,” highlighting the importance of good supervision in such environments. The marine park’s waters tend to have better visibility, although weather conditions can influence the clarity.
