The Andaman Sea offers world-class diving, with the Gentle Giant providing access to both northern and southern regions. Northern sites like the Similan Islands, Koh Bon, Koh Tachai, and the famous Richelieu Rock are renowned for their pelagic encounters, including whale sharks and manta rays, as well as vibrant soft corals and diverse reef fish. The southern sites, such as Hin Daeng and Hin Muang, are famous for their dramatic pinnacles and the chance to see large schools of fish and more pelagic species. Guests can expect 22 dives over a 7-day trip, including exciting night dives. The vessel's dive deck is shaded for comfort, and a dedicated rinse tank is available for underwater camera equipment. Dive groups are kept small, ensuring personalized guidance from experienced instructors who are adept at spotting marine life and navigating the sites. The crew provides excellent assistance with gear, making the diving experience smooth and enjoyable for all skill levels.

We strongly recommend all guests to purchase comprehensive dive accident insurance and trip cancellation insurance before departure. Dive accident insurance covers medical treatment, hyperbaric chamber costs, and emergency evacuation in the event of a diving incident. Trip cancellation insurance protects your financial investment — not only if you need to cancel or cut short your trip due to personal illness, injury, or other unforeseen circumstances, but also if the trip is postponed or cancelled by the operator due to severe weather, technical issues, or other operational reasons. In the unlikely event of operator insolvency, cancellation insurance can also help recover your payments. Please ensure your policies are valid for the entire duration of your trip and cover the planned activities.
