Scuba Diving Day Trips in Koh Chang – Your Perfect Ocean Escape
Discover the underwater beauty of Koh Chang’s top dive sites on our full-day trips into Mu Koh Chang National Marine Park. Whether you want to try scuba for the first time with a Try Dive, refresh your skills with a Refresher Course, or enjoy guided Fun Dives, our SDI, TDI and PADI instructors make every trip safe, fun, and unforgettable.
On your adventure you’ll encounter tropical marine life, vibrant coral gardens, and—if conditions allow—even the famous HTMS Chang Wreck. Curious about what you might spot? From colorful reef fish and barracudas to the occasional whale shark – every dive site offers a new highlight.
Our trips take place aboard our custom dive boat Pirm Udom Sub, designed for comfort and safety. Spacious decks, shaded areas, fresh Thai meals, and modern dive facilities make your day at sea enjoyable. For extended bottom times, Nitrox is available on request.
Every day trip is carefully planned – from sunrise departure to a relaxed return. We keep groups small, provide full equipment if needed, and offer extras like diving insurance and GoPro rental to capture your memories. Families, couples, and solo travelers are all welcome.
