Half Dome

Half Dome is the significant icon of Yosemite National Park and arguably the most famous and coveted day hike in North America. Looming almost 5,000 feet (1,500m) above Yosemite Valley, the massive granite dome challenges hikers with a grueling, massive elevation gain. The classic route ascends via the dramatic Mist Trail, passing two massive waterfalls, ascending through dense pine forests to Little Yosemite Valley, and finally climbing the stark, exposed rock of Sub Dome. The grand finale is the legendary 'Cables' section—two metal cables suspended by steel poles drilled into the sheer, 45-degree granite face. Hikers should use their upper body strength to pull themselves up the final 400 feet of slick granite to a flat summary that offers scenic views of the entire Yosemite Valley and the High Sierra.

Standing between two oceans. Volcán Barú is an active stratovolcano and the highest point in Panama (3,474m). This is a uniquely challenging hike that covers 27km (17 miles) round-trip, typically done at night to reach the summit for sunrise. On exceptionally clear days, this is one of the only places on Earth where you can see both the Pacific Ocean and the Caribbean Sea simultaneously. The trail is a rugged, unrelenting climb through cloud forest and volcanic rock to a summit filled with communication antennas and scenic 360-degree views.
