We visited on a weekend and it was rather crowded. We came in at the back entrance and it was a pleasant quiet climb up to the top where the views may have been spectacular if it was not for the smog. The climb down the other side to the temple was very busy. I am tempted to say ‘too busy’. The cave with the Thousand Buddhas was very interesting (at first). The cave was enormous – it seemed to go on and on but I guess it still stayed quite interesting up to the end. The walk round to the enormous golden Buddha was nice and the Buddha itself was spectacular.
This is good weekday day out in Jinan. I am not sure that you need to climb to the top if you are not very fit.
