3. Half Dome (8,839ft), Yosemite National Park, California
One of the most iconic peaks in the world is Yosemite National Park‘s Half Dome. Recognized the world over as the logo for the outdoor retailer The North Face, Half dome rises over 8,000 feet above the awe-inspiring Yosemite Valley, providing panoramic views of the Sierra Nevada Mountain Range. Due to its rise in popularity over the past few years, the park has instituted a lottery system for those wishing to stand atop the granite giant. The lottery randomly selects 225 lucky hikers for each day early in the season while reserving another 50 slots for a daily lottery. As with most summit attempts, hikers should begin early.
