4.5-mile challenging loop near Yosemite Valley—3 hours of steep climbs, misty vistas, and granite grandeur. Start at Happy Isles, trek the John Muir Trail to Mist Trail’s roaring Vernal Falls, then follow to Emerald Pool and Clark Point for sweeping views of waterfalls and domed peaks. Best April–Oct; winter closes upper Muir Trail (check closures!). No dogs allowed—pack grit, not Fido. Conquer it, and the valley’s magic’s yours. #Outdoor #Hiking #YosemiteHikes #VernalFallsTrail
