The granite of Halfdome in Yosemite, California makes a central appearance on the 63 mile challenge. Concerned about traffic? An early-morning start will have you avoiding cars as you grind your way up the 23-mile long grade. Once the sun is up, and on your return, you’ll be descending into the valley and away from the tourist traffic. For those looking for a less challenging route, the first five miles of the Glacier Point OAB route travel through the valley floor providing an entirely different experience than any car-bound journey you’ve had in the area. Bring a third water bottle and daytime lights.
