About Us

Who Are We?

Hollow Mountain Extreme Adventure Park is an adventure park located just outside Ao Nang in Krabi province, Southern Thailand. Our adventure park is built inside and on the surface of Hollow Mountain, which for many people will be their first up-close look at a “karst” mountain. The mountain is riddled with caves, including the enormous Main Cave where much of the action takes place. The park was designed, built and is managed by Simon Ramsden, a British engineer.

Our values are safety, fun, and harmony. Therefore:

  • Our park infrastructure is safe and uses only state of the art equipment
  • Our carbon footprint is negative – we emit less carbon than we extract, and
  • We invest THB 150 per customer into the local community.


What is Our Mission?

Our mission is to be Asia’s safest and most thrilling out-of-water adventure park, while ensuring that the community and environment in which we operate benefit from our success.
