In truth, the only outdoor activity you need to worry about in Klong Muang is sitting on the golden beach, soaking up a few rays. But for the more adventurous, venturing into nearby Ao Nang will bring you to several PADI Dive Shops.
The waters around the twin islands of Koh Phi-Phi are world famous dive sites and include the legendary King Cruiser ship wreck. There are also several operators on Phi-Phi itself.
For those who want take advantage of the waters above the surface, there are a couple of operators who organise tours around the Klong Muang area, either sailing or kayaking as well as the world famous rock climbing at Koh Phi-Phi and Railay Beach.
