Uthai Thani - Huai Khun Kaeo Reservoir

This reservoir in Huai Khot district is your typical run-of-the-mill reservoir. But on an island connected to the mainland by a causeway, there is a small spring that sprouts up to the surface: Ban Samo Thong Hot Spring. The water is clear (although with the aroma of sulfur) and has been put to good use.

The Royal Irrigation Department did some landscaping on the small island to create a rest area for visitors. Huts with mineral baths and a swimming pool with view of the reservoir are available for tourists.

Small bungalows can be rented for those who want quiet evenings / nights on the edge of a reservoir. I enjoyed my stay there and can recommend that you give it a try.

On your way to the Ban Samo Thong Hot Spring, you are likely to pass through Ban Rai. I did and I noticed some signs to caves and to an "old tree". I decided to take a look and as I got closer to the tree, the signs indicated different ages for the tree. I don't know which estimate is correct, but the tree is apparently between 250 and 400 years old.

Whatever the tree's real age is, it is impressive, but it is not worth a major detour to see the tree. Because once you get there, there is nothing else. You (and the tree) are in a small patch of forest surrounded by younger trees, and that's pretty much it.
