I've done "upper north" and this was tons better. We intended to do "Lower" but couldnt find the creek crossing and would up on Gus Froh. When you get to what APPEARS to be the end just after the creek & waterfall climb up to the top of the rock for the view. Then youll see a path and follow it and it goes miles further. Lots of ups and down, a SPECTACULAR view near one of the mountain climbing rocks, just a lot of fun.
