It’s a serious 3.2 mile uphill hike through a mountain pass to get to the top of Upper Yosemite Falls. Mountain miles are way different from flatland miles. It took me 6 hours of hiking time, round trip. There were lots of ill-prepared people in sneakers carrying a pint of water trying the hike, and plenty of people hobbling down the trail.
But the view. Wow.
