Sleeping on the mountain is convenient for the sunrise, but it is much more expensive and rooms are simpler than in Tài'ān. Look for signs posting 如家 (rújiā) or 宾馆 (bīnguǎn) at the summit area along Tian Jie for inns starting from around ¥120 and going way up on weekends. Rates can triple during holiday periods, but during slack periods you can bargain for discounts.
