Took us around 3.5 - 4 hours in total from the top of the path to the waterfall and back. Could be done quicker if you're in a rush but the views alone will slow you down.
Falling rocks in the gorge, a couple of climbs that you won't want to fall from. I image a ton of fast water in the wet season and flash floods during rain
We did this route without any ropes but they would have been nice at certain points
First off from the GPS point take the path on your right-hand side. It will get you in the water. Go upstream. Really REALLY great place. We went during a drought when nothing else around had any water and it was still a good time. As such I imagine this is best done during the dry season. There were a couple of climbs that weren't all that easy. I managed them and I am no pro, but you'll want to have had a bit of experience scrambling around rocks without ropes to get past a couple of the falls. There are also a couple of sections where there will be ropes along the side up into the jungle and around a couple of obstacles so keep an eye out for those. Some cool caves that would make a great place for a tent can also be found for anyone into that sorta thing.
