John Gray’s crew cares about you and nature; they speak a decent to exciting English and will tell you a lot about what you are about to see and discover. Boats never get crowded, and food on board is excellent. You’ll be asked to respect Nature around you as much as they do, which means no touching, no loud talking and of course no smoking while you are exploring the famous ‘Hongs’ (enclosed lagoons, usually only accessible through a narrow tunnel when tides permit). They also try to avoid crowded places: a Hong with a hundred canoes in it is not exactly a grand vision of nature at its best. On the way, you will be amazed to see the size and the amount of these fantastic limestone formations rising straight up from the sea and covered with dense vegetation. While moving from one island to another, the crew will throw some chicken bits in the air, and dozens ‘Bramany Kites’ (some Sea Eagles) will flock and dive behind the boat. https://www.phuket101.net/kayaking-in-phang-nga-bay/

There are hundreds of caves, underground rivers and long underground passages with stalactites and stalagmites. In 2005 the park has been discovered a new species of gecko.

Serious exploration of the caves began only in the 1990s when it first Cavers forced deep into Phong Nha Cave, one of the longest cave systems in the world. Paradise Cave was discovered in 2005, and in 2009 a team found the world's largest cave - the Son Doong. In 2015, the public was given access to two cave systems.
