The Phu Kradung challenge is an enduring though normal walking trail and can be done by anyone in good health with a reasonable physical condition and a good sense of adventure. The trail is steep and sometimes requires creative walking but it is not difficult. There is no mountaineering involved and no special equipment or climbing skills are required. Food and drinks are available on the way. We recommend the following things to take with you. The park is closed in the rainy season between June 1st and September 30.
