Ban Tha Chang Spring is a point where after disappearing underground a water source reemerges at the surface creating a pool seemingly from nowhere. The proof is the crystal clear water the result of filtration through the bedrock. Tha Chang Spring attracts many visitors, eager to swim in the clear water of the pool formed by the spring. Access to the pool is free although parking nearby will cost 20 baht. Bringing swimwear is practically essential to enjoy this attraction although the banks are quite suitable for picnicking.
