Wat Phu Tok or sometimes spelled Wat Phu Thok is in the Thai province....Bueng Kan. It is a very enjoyable climb which is sometimes very strenuous so bring plenty of water. The day we went in April, 2024 it was very hot and the air quality was quite poor. If you are someone that does not like heights this may no be a good choice. If you are not fit I would also think that it would not be a good choice. You should climb at your comfort level.
