Just did this today. Let's start with what this is not, it's not a hike, a hike is a long walk with maybe some steps with maybe a steep gradient or two that you can walk.

What this is a 2.8k climb up very steep stone step trail, when I say steps not manmade concrete steps this a climb that has been hacked into the steep jungle cliff side and is very uneven and requires a lot of upper body strength as a lot of the way you will be pulling yourselves up the climb using either metal handles of a guide rail. Yes young people will find it tough but easy as long as they have the right foot wear. But if though trail climbing is your first time be very prepared. It's steep very steep in places, which makes the coming down twice as hard as going up.

If it has rained, like it did the day before I did it then it is very treacherous as the steps are glass smooth, small and very slippery. You need proper footwear, and gloves as you will be using your hands a lot.

With all that in mind and you do make it to the 4th level, the views are spectacular.

One more thing, as I said this is a jungle trek/trail/ climb and as such there are snakes in the trees I saw 2 today curled up over the trail, bright yellow with black stripes and they are poisonous.
