Mist Trail to Vernal Falls

Jake here. The Mist Trail is the busiest piece of granite staircase in Yosemite Valley, and for good reason — it climbs straight up the Merced past Vernal Fall, and in spring you get soaked doing it. It's also short enough that people show up in cotton tees and flip-flops, then realize halfway up that wet granite at a 30-degree angle is its own kind of problem.

The trail

The 4.5 km out-and-back starts at the Happy Isles trailhead in the east end of the Valley. The first kilometer is paved and deceptively easy — a steady grade up to the Vernal Fall footbridge, where most casual visitors stop, take a photo, and turn around. That's your first decision point and where the crowd thins.

Past the bridge, the trail splits. Stay right for the Mist Trail proper. The next stretch is the work: roughly 600 stone steps cut into the cliff alongside the fall, climbing about 300 m total to the top of Vernal. In May and June the spray is constant and the steps run with water — footing is genuinely slick, and there's a cable handrail on the exposed sections for a reason. Kids do it, dogs can't (no pets on this trail), and people in road runners regret their choices.

The top of Vernal Fall opens onto a flat slab of granite with the Merced sliding past toward the lip. The railing exists because people have died here. Stay behind it. Most hikers turn around at this point for the 4.5 km round trip; the trail continues up to Nevada Fall and the Mist/JMT loop if you want more.

When to go

Late May through June is when the fall is at full volume and the mist is heaviest — wettest, most dramatic, and most slippery. July and August the flow drops, the steps dry out, and the climb is hotter but easier underfoot. By September the fall can be a trickle. Winter (roughly November through April) the Mist Trail section is typically closed and you're routed up the John Muir Trail instead, which is longer but safer when granite is icy.

For crowds: expect a steady line of people on the steps from about 9 a.m. to 4 p.m. in summer. Starting at sunrise is the only real fix.

What to know before you go

• Permits: No permit needed for the day hike itself, but you need a Yosemite entrance reservation in peak season — check the NPS site before you drive in, the rules change year to year.
• Parking: Don't try to park at Happy Isles. Use the day-use lots in Yosemite Village or Curry Village and take the free Valley shuttle to stop 16 (Happy Isles).
• Water: There's a fountain near the trailhead and one at the Vernal Fall footbridge in season. Above the bridge, nothing potable — bring at least a liter per person.
• Navigation: The trail is obvious and signed; the hazard isn't routefinding, it's the wet granite. Don't step over railings for photos. The pool at the top of Vernal looks calm and isn't.
• Around 3 hours is realistic for the round trip with stops. Strong hikers do it in two; with kids, plan four.

What to bring

A rain shell or something you don't mind soaking — in spring you will get drenched on the steps. Shoes with actual tread; trail runners or light hikers, not sandals. Sun protection for the exposed switchbacks above the fall. A liter or more of water per person in summer heat. A small dry bag for your phone and camera if you're going up in May or June. Trekking poles help on the descent, especially on wet stone.

Variations

• Footbridge turnaround: If the steps look sketchy or you've got young kids, the paved climb to the Vernal Fall footbridge is about a third of the distance and gets you a solid view of the fall.
• Top of Nevada Fall loop: Continue up the Mist Trail past Vernal to the top of Nevada Fall, then descend via the John Muir Trail. Roughly 11 km round trip, ~600 m more gain, and a much fuller day.
• Half Dome add-on: The same trail is the start of the Half Dome route. That requires a separate lottery permit, cables season only (typically late May through mid-October), and is a 22+ km, 1,500 m gain commitment — a different category of day entirely.
