I am a native of Chengdu, and I am currently engaged in tourism-related businesses. This route can be said to have gone through countless times. The most suitable season for Zoige Prairie is June to August. In mid-June, the flowers in Huahu Lake were basically in full bloom. When I went to Huahu Lake in July and August, I basically couldn&;t see the flowers. However, from July to August, I could still see some wild flowers on the grassland, and the weather began to get cold after opening in August. I just got back from Zoige in August, and my car was frozen in the morning. For regular tour groups, they will stop at Chuanzhusi for one night, and then branch off from Chuanzhusi. On the left, they will go to Zoige, and on the right, they will go to Jiuzhaigou (not yet open). I suggest that you can stay in Songpan for one night and visit the ancient city of Songzhou in the evening. Accommodation ranges from cheap to expensive and is very developed. 1. Check the road conditions in advance, because if it rains, Duwen Expressway will sometimes close the road. 2. Songpan has a section of road under repair. When leaving Songpan for Zoige, try to leave Songpan before 9: 00 in the morning, otherwise you will have to wait for unilateral release, and it will take at least 2 hours at a time. 3. The expressway can only go to Wenchuan, and there is no expressway behind it. The road is still easy to walk. If it rains, you must pay attention to slow down and pay attention to rolling stones and landslides. Water and food should be prepared in advance in the car, and you won&;t go hungry in case of traffic jam. 5. When entering Zoige, slow down. There are often groups of yaks and sheep crossing the road, so pay attention to avoid them. 6. Take care of the environment and prepare garbage bags with the car. 7. Riding a horse only costs 20 yuan once, which is the general price to avoid being pitted. Finally, I wish you a pleasant journey. If you need to know more details, you can answer them by private letter.
