It's a little tough to climb but the view's are definitely worth it
This hike is harder than it seems by looking at the map ----- lots of pretty steep pitches while simultaneously boulder hopping, so its difficult to get into a good climbing stride. The view from the top is well worth it, and you'll likely have the place all to yourself!
