Sanmenjiang Forest Park is Liuzhou's natural oxygen bar. It is really the feeling of the deep mountains. The air is very fresh. It is along the repaired mountain road. There are large trees towering into the sky on both sides, but obviously the entire forest park has not been built yet. Many of the attractions on the guide map have not yet opened, they are all mud roads in the mountains, and they have not stepped foot in view of safety considerations. The mountains are deep, but there are security booths at each distance, and there are security guards on duty, which is relatively safe. People who go are best to buy water at the mountain gate, do a good job of sun protection, and also prevent mosquito bites. In short, oxygen is taken to the Sanmen River, climbing the mountain can also exercise, and the mountain road is not steep.
