If you choose a bus as your transportation, it will probably take at least 4 hours. However watching the sunset or sunrise, and trekking to see the sea of clouds atop the mountain are a few activities that are worth that long trip.
From here a trail leads up to the viewing point on top of the hill, a distance of 1.8 kms. It has a perfect spot for taking photos is the area of 50 meters before going to the top. The sheer cliff of Phu Chi Fah can be seen spectacular scenes, especially the sea of mist at sunrise. If the sky is clear, you will be able to see the views over Mekong River and deep into Laos. In the morning, the fog covers the mountains, and all you can sea are the peaks peaking out of the fog. Thai people call it islands in the fog (ทะเลหมอก).
You probably have seen some beautiful sunrises before, but we are sure that that one in Phi Chi Fah will be one of the most spectacular you have seen
