Guiyang Tianhetan Park is a park with waterfalls and karst caves as a whole. The park is mainly divided into three parts. As soon as it enters the park, it is a scenic spot with Guiyang story as its theme. In fact, it is a dining area, mostly the buildings of the Republic of China and some statues. The second is the Waterfall Group, which is mainly composed of Wolong Lake. Personally, I think this is the most beautiful scenic spot of Tianhe Lake. The third is the water cave and the drought cave, which are respectively a water cave to be seen by boat and a drought cave to be walked. Water cave scenery is relatively general. After boarding a boat, it arrives at the dry cave. The scenery of the dry cave is OK, but there is no explanation. Every scenic spot can only be imagined by itself. As for sightseeing buses, the ticket is 30 yuan round trip. It seems that there is no one-way purchase. If you have good physical strength, you are advised to walk. The sightseeing bus goes directly to the boarding dock of the water cave. It's still a walk from here to the Falls. If you want to take a return bus, you have to go back.
