Two things are most memorable about the summit hike at Doi Inthanon.

1) The beautiful forest and trail like you see here

2) Our poor "guide" coughing up a lung. You are required to hire out a local "guide" to walk around the summit of Doi Inthanon. This may be predominantly good for the indigenous people who live on the mountain, but our particular "guide" needed to be home in bed. Amazingly, none of us ended up sick afterwards...
