I did the 1 day tour of Doi Inathanon park. The trek was good and the climate was perfect in Jan, initially chilly with a warm sun as the day progressed.
I was very happy that it was easy to book the tour just one day before. The person who answered the phone number on their website spoke English and confirmed the tours and pick up arrangements very quickly.
The trek itself, while not difficult, has some moderate uphill climbs that could be strenuous depending on your physical fitness. Kudos to our guide, Boon, who made sure that everyone was able to keep up and that there were frequent rest stops
The most enjoyable part of the tour for me was the trek followed by the tour of the Karen village (getting to learn about the houses, animals, bit of history of the place n people) with lunch at the village. The tour also included a visit to the twin pagodas, a waterfall and the top of the mountain.
Would love to try the longer trips next time.
I was happy that the company took feedback at the end of tour.
