We spent the last while in a region of Thailand called Pangmapha which is famous for its hundreds of caves. We stayed in a village called Ban Tham Lod, which gets its name from Tham Lod (through cave) which is a massive cave that bisects a mountain. We stayed at a place called Cave Lodge which is run by a “crazy Aussie” who has been in the area for almost 30 years.
The place is loaded with character, and one could spend months or years exploring the area.
The only Internet we could find was in Sappong (8kms away) and it was VERY slow dial up.
