This cave is worth a visit if you're in the area, though it may not be the most spectacular one you've seen.
To reach the entrance, you'll need to climb 600 steps, but they're not too steep and should be manageable for most people with an average fitness level. Once you reach the top where the golden Buddha is, venture into the cave and walk all the way through to the other end, where you'll find an opening. Climbing the stairs there will reward you with great views.
While the cave is lit, it's a good idea to bring a torch for extra visibility.
Before climbing up the stairs, for safety reasons, you'll have to register with a guard and sign out when you leave. The entrance is free but donations at the temple are appreciated – donation boxes are available at the bottom and top.
