The tallest peak in Yosemite National Park is Mount Lyell at 13,120 feet. Coming in a close second, is Mount Dana at 13,061 feet. Like Mount Hoffmann in the geographic center of the park, there is no “trail” to the summit of Mount Dana that is maintained by the National Park Service. Having said that, for those that are willing to route find, brave substantial elevation gain, and risk venturing off the three mile one way distance in minor ways, the payoff is a summit with great three hundred and sixty degree views of the Sierra Nevada mountain range, the high country of Yosemite, and Mono Lake to the east.
