South of Petchabun....
Kwang Sai G/H...south of Petchabun, where Hwy-21 intersects with road 225. The G/H is about 300-meters from the intersection, on the SW (?) corner of road 225.
Signage is in Thai only. Not much nearby, easy to find. 300-Bt.
087-8429446 or 056-731843 but reservation likely not needed.
Decent value. Many older rooms, each about 38sqM. Dbl-bed, rooms have both A/C (no key card needed) and a fan, HW, TV (PSI-200 channels), secure parking and...free WiFi.
Run by a genial older Thai couple & their 2 younger teen daughters. Latter speak English.
I stopped there as it was getting dark and avoid night riding due to my bikes dim headlight. The only restaurant nearby was closing and the G/H provided me with a menu and phoned an area diner. Hot food was delivered in 20-minutes. 30-Bt including a bottle of water.
