I went up here for lunch yesterday. It's phenomenal. The setting is magnificent, the views are terrific, the food great. All of the buddhas on the walk up have a different personality being expressed. The walk itself though is quite challenging. Its steep with over 400 steps. By the time I reached the top on a July afternoon I was drenched with sweat.
If you do undertake the walk up it may be smart to go early in the morning when its less hot, or of course to go at an alternative time to the height of summer. Take a bottle of water for the journey. There's resting benches dotted alongside the walk up.
Cons: 430 steep steps uphill
