I can’t add more than description about what the place is or what to expect, there are a lot of helpful reviews. But I can add some tips about how to get to here since there is almost zero information about it (or at least that I was able to find). We left from BaiSe train station, which is 6 minutes walking from the train station (it’s called Highway coach station or something like that). There you can go to the ticket office and ask for tickets to Jingxi (they will understand the pronunciation). Good luck dealing with Chinese stuff to know what is your bus and when you can get in (they are really helpful anyway). Once in Jiangxi you have to go to the south terminal station (our bus from BaiSe arrived to the main station), which is 5 minutes walking. There will be a lot of drivers asking for rides, unless you know Chinese or want to deal with them just ignore them. At the south station, they will also understand Tonglin pronunciation so you will be safe. You have to go to the ticket office and make them understand what you want, they are nice people as well. You will have to deal to know which bus it’s the one you have to take but saying Tonglin and showing the ticket should be enough to make them understand. Enjoy the travel if you are not used to South Asian roads. They will let you know when to leave the bus. You will be seeing panel with the Tonglin distance you will be totally safe. You will get off on the road, so just look at both sides and cross and you will be there. Once there buy the tickets, enjoy the nice views and activities and Filis the signs to get back. There are staff around the way that will let you know where to go. At the end you will be asked for stop until the bus comes for you (it’s free and it will take you back to the entrance). Now, to get back. Go to the intersection where you took off the bus and wait there for the bus to come. Just make a sign and they will stop. You will get back to Jingxin and you will have to make the inverse route this time, nothing tricky here. In Jinxgin they will know you go to BaiSe so you will be safe. There is a checkpoint where they ignored us on our way there, but made the bus stop for a while on the return trip. The police officers will check your passport and ask your itinerary and blablabla. Don’t worry but be aware of this.

I took a local bus about 5 minute walk from the main station to the turnoff for the Tongling Grand Canyon and found a simple hotel for I think 80CNY. It was a few minute walk from the rafting for Gulong Mountain. It cost me 190 and I think cheaper from other reviews if you are 2. My guide asked for a tip and I gave him 50 and it was well worth it, he paddled so hard and was super pleasant. Be prepared your guide will ask for a tip and please give it. The rafting was great. The water was not deep and I didn't get wet, but it was relaxing and we went through 3 caves. We floated down the river not seeing anybody else although tour groups bring their clients. I then walked the 1 kilometer plus to the canyon entrance. This site should be amazing but they have put up so many colored lights going down the stairs of the cavern it takes away from the nature. The waterfall is nice but even there they have built a curtain and no longer seems natural. I'd 100% do the rafting and probably the canyon too but it was disappointing knowing how great it should be.
