You know me, I am curious, I went down the small path that goes below the platform by following a Thai sign indicating the "monk's cave". If the cave is not impressive, you quickly find yourselves in a jungle scenery along large rocks symbolically supported by wooden sticks placed by the people. You also have the feeling of being in a secret place because if there are a lot of people above, here, I was alone.
Even if the view from this temple is one of the most beautiful you can find over the Mekong, getting here from Nong Khai only for the SkyWalk might be a lot of road but there are interesting waterfalls in the area and a few visits in the neighboring province of Udon Thani which are only a few tens of kilometers away. All together can make a nice day of visit.
