About This Route
The Mist Trail in Yosemite National Park offers one of the most iconic day hikes, climbing 1.7 miles round-trip from Happy Isles in Yosemite Valley to the base of 317-foot Vernal Fall. Expect wet granite stairs slick with mist from the cascading waterfall, steep switchbacks, and breathtaking views of the Merced River plunging into Emerald Pool. This trail sees heavy foot traffic, especially in spring when water flow peaks, but crowds can lead to accidents. According to the National Park Service (NPS), slippery conditions here contribute to numerous rescues annually. Hikers should prepare for elevation gain of 1,000 feet and variable weather that can turn a sunny morning into a foggy afternoon.
Safety Considerations
Stay on the established trail to avoid slips on slick granite; the NPS reports that straying off-trail near Vernal Fall has caused fatal falls. Carry and drink at least one quart of water every two hours, as dehydration hits fast on exposed sections. Sturdy footwear with aggressive tread, like Salomon X Ultra boots, is essential for traction on wet stairs. Know your limits: the steep climb exacerbates heart conditions or knee issues, so monitor symptoms and turn back if dizzy. Follow Leave No Trace principles by packing out all waste, and hike with a buddy using the HIKE SMART acronym from Yosemite Search and Rescue (YOSAR): Have a plan, Inform others, Know conditions, Eat and hydrate, Stay on trail, Ask for help, Manage risks, Turn back if needed, Reach camp/trailhead safely.

Emergency Tips
If injured near the falls, blow your whistle three times and wait; do not attempt self-rescue on slick terrain. Signal YOSAR via 911 or satellite communicator like Garmin inReach. Hypothermia risk is high in mist: seek shelter under trees and share body heat.
