10 days hiking tour? A brave idea!ha I suggest you find some youth hostel to live in for it's economical, clean and comfortable. Such as Migu international youth hostel or Jiuzhaigou Tiantang youth hostel.

Do you mean hike inside the park because at most you only need two days to see everything and the cost per day is around 310rmb. Outside the park there are no established trails the hostel owner I stayed at had a taxi drive me to where the villagers hike in the backcountry and warned me about getting lost I had to follow based on where Ii could track broken ground.
