Although the firefly hole is not very far from the Grand Canyon, the traffic is not convenient. If there is a shuttle bus, it is perfect. Suitable for self-driving, with the group, but there is a time limit with the group, I feel that it is most suitable for self-driving. Ctrip has to change paper tickets to book tickets, all kinds of queues. The scenery is good, the rafting is also played, and the fantasy paradise is also played. The rafting of the firefly hole does not have the excitement of the Grand Canyon. Overall it is not bad. The things in the Grand Canyon are not expensive and feel very suitable. There are individuals in the wormhole that can be a paradise, and children like it very much. The child lost the water gun when playing, and then a student brother sent it back. Thanks to 🙏 It rained from the wormhole, traffic jam, and couldn't get a taxi. Thanks to Lu Q Audi brother for taking us to a good taxi place! The master Linyi Didi I met was also very good! Thanks 🙏 I want to go again if I have the opportunity.
