The 2 most popular times of the day to visit the Chiang Khan Skywalk are at dawn to contemplate the sea of mist in the cold and wet seasons or, of course, at sunset. It is not a visit I recommend if you are prone to vertigo ! ;)
Since its opening to the public, the place has developed a lot with a parking lot with a lot of pickups for the climb, ATV rental and even an elephant camp. A small amusement park in tourist factory mode is coming, which I personally like less. Even if the view remains beautiful. If possible, avoid coming to the Chiang Khan Skywalk on weekends and public holidays because it is very popular with Thais who love coming to Chiang Khan and the skywalk.
