I did this yesterday and we loved it! Easy going for the first few miles with gorgeous smaller waterfalls... it opens up to huge boulders and the view is incredible once you break through the tree line.
Definitely make sure you’re wearing good shoes and proper clothes - the temp difference was certainly notable even mid way up.
We started on the short line / King’s ravine and cut across before we went up the entire summit and back down the airline trail.
Overall it was about 7 miles and took us about 6 hours including a couple small breaks for lunch and snacks.
Definitely a favorite of ours out of the other hikes we’ve done in the presidential range!
