These two fine caves in the Lam Khlong Ngu National Park, Kanchanaburi, will be open to visitors between 29 February and 4 May 2020. Visitors must pre-book, should be between 15 and 60 years old, able to swim and physically fit.
I've accepted the inevitable, and come to the conclusion that a Facebook group for Thai cavers might have a use for trip reports, finding caving partners, planning expeditions, etc. and allowing the wider caving world to find the active cavers in the country.
This group, Thailand Caving, has been set up as a closed group. Please contact me, via the group on Facebook, for an invite to join.
