Although there is a steep hiking path from the top, it's also possible to drive down to the bottom where hiking to the waterfall takes only 20 minutes, round trip.
The path takes you near the top of the waterfall where the water flows over the path and you'll walk behind the water curtain during the rainy season.
The path continues to the base of the waterfall where there is depression in the rock, behind the waterfall which is the water curtain cave.
