Ko Muk:

Ko Muk is not to be missed. Spectacular scenery , lots of opportunity for exploring the caves, creeks and inlets by dinghy or kayak , a fresh water spring, one or two small restautrants ashore and best of all, the Emerald Cave. This cave is actually a 60 meter long ( 200 ft ) very large tunnel leading to a completely land locked lagoon which is Thailand’s largest hong. You can negotiate the cave by dinghy ( at low tide ), kayak or, best of all, swimming. Even at high spring tides you always have a meter or more airspace so it is completely safe. The hong itself is fringed by beautiful beaches and lush tropical forest. “Unforgettable experience” is a term frequently heard from those who have done it.
