Easy time finding the trail and relatively not muddy on the way up. Started raining once I got to the falls and that made everything a sloppy mess on the way back down. Waterfall was in full display considering the amount of rain we've been having.
My friend nicknames this the "Maunawili Mud Trail", and I agree! It is not a particularly long or steep trail - just a lot of mucking through the jungle. Be VERY careful with your footing. You'll be climbing over and under branches, balancing on tree roots and rocks to try and avoid the mud, and crossing the stream several times. If you're careful you can probably make it across the stream by balancing on the rocks, through at the very end I did end up getting my shoes wet when I missed the rock I was trying to step on.
Toward the end there are some steps going up and a really nice view, and then you will descend again and make it to the Falls. The waterfall is quite picturesque, and so beautifully tucked into the jungle. There were a couple groups of people jumping off the ledge into the pool below, which was cool to see! I honestly have no idea how they made it up there though.
Enjoy, and bring bug spray!
