Plan your trip in advance, especially book the room in advance, if possible. Try not to go in winter because even during summer, certain hostel's floor is wet! due to the weather and atmosphere. If you visit to the Tourist Centre, they recommend you to go to 4 places (if you have limited time time). Huashi Lake (I think at Mottled Stone Sea), Butterfly Shoal, Small Jiuzhaigou, Three Enchantments of Lissome Water (I think you will see the(containing Vanilla Cascade, Dragon Waterfall, and Moon Cave Water Screen). If you travel there by own car, you just need to pay the entrance fee, I think it's RMB 65 and for the raft. As we were stuck in the jam (try not to travel there during public holiday and weekends), we only went to the four main attraction suggested by the Tourist Centre. Remember to wear good walking shoe and if you want to get down to the lake, stream or water, buy their hand-made slippers made from corn peel.

First of all - I strongly reccomend you to buy also the bus ticket, when buying the entrance ticket (at the place where buses from Qionglai and Chengdu drop you off), because it's really far from there to the entrance, and if you have only one day there, it's impossible to see almost anything wthout using the bus. We walked from the main gate 山门 to the road near by 乐安 (almost 2-3 hour walk) and from there we took a bus(it costs more if you don't buy the bus ticket at the entrance) to the furthes spot, where the buses take you 正天台. There are loads of annoying people trying to persuade you to eat at their restaurant... We wanted to see some of the top waterfalls, but when we got there, we found out we would have to pay another 15 yuan (one way) to get over a lake...so we decided not to do that... So we wanted to walk down, but noone was able to help us to find the path for tourists, so we walked on the road...quite annoying... So to sum up - it was pretty, but I there are (in Sichuan) other beautiful places where you don't have to pay an entrance fee...
