With only eight customers onboard, supervised by two professional dive staff, we are able to offer a very personalised trip and friendly service with the emphasis on safety, good food and diving, diving, diving...

During the trip there is plenty of time for visiting the different beaches and exploring the islands, including the chance to climb to the top of the famous rock formation at Ao Guerk for beautiful views over the bay, or visit the National Park Headquarters on Koh Miang.

Enjoy the diverse diving of the Similans, from the extensive coral reefs to the canyons and gullies formed by underwater granite boulders with numerous swimthroughs. Also you will make a dive along the near vertical slope of Koh Bon - the only true wall dive in this area, and keep a careful watch for the manta rays, often seen playing in the waters near this island.

And in the evening, relax on our open-air sundeck. With no air-conditioning onboard and therefore no generator running at night, the Nangnuan is one of the last boats in the islands offering total peace and quiet. Bring along your guitar - this is the perfect setting for those lazy tropical evenings.
