Fortunately it was a cool day and we bought water at the bottom before the climb. The climb is very difficult, 611 steps but fortunately the climb is broken by places with seats to rest. After making the climb, you are greeted by the Buddha who sits at the entrance to the cave and you then walk in. Decent shoes help here, the floor is very slippery in places and the ground is quite uneven. Once you're in the main cave you are struck by the enormity of the place, its huge! These caves are beautiful, worth the climb but be warned, getting up there isn't easy.
