There are two crux's in the route. The first one is when you get to the roof. The second one is trying to pull through the off width roof. Height helps.
Follow the finger crack up to the roof then work your way in to the parallel finger cracks up to the ledge. Then work you way up the off width crack and over the roof to the anchors.
This is route number 1 on the picture.
No pro needed just top rope the route. I tried to aid some of it but it was a little sketchy.
Anchors are webbing tied to trees with 2 oval carabiners.
