Yosemite is a hiker’s paradise year-round, but when summer temperatures soar, it’s important to plan your hikes wisely. Luckily, Yosemite National Park offers a variety of trails that provide shade, access to water, and cooler elevations, making it possible to enjoy the beauty of the park without overheating. Here’s your guide to staying cool while hiking in Yosemite during those hot summer days.
Why Yosemite Gets Hot in Summer
From June through August, Yosemite Valley and the lower elevations of the park can see temperatures in the 90s°F (30s°C). With granite walls radiating heat and limited shade in some areas, it’s crucial to choose your trails carefully and prioritize hydration, early start times, and rest in shady spots.
Mist Trail to Vernal Fall
Distance: 3 miles round trip to Vernal Fall
Best for: Shade, waterfall mist, and natural AC
One of the most iconic trails in Yosemite is also one of the coolest, literally. The Mist Trail earns its name for good reason. As you climb alongside the Merced River to Vernal Fall, you’re treated to the refreshing spray of the falls. This trail stays relatively shaded in the morning and provides a great spot to cool off mid-hike. Be prepared to get a little wet, in a good way.

Tuolumne Meadows Trails
Distance: Varies by trail
Best for: Higher elevation and cooler temps
If you’re looking to escape the heat entirely, head to higher ground. Tuolumne Meadows sits at 8,600 feet above sea level and offers a cooler, alpine environment even on the hottest days. Trails like Lyell Canyon or the Gaylor Lakes hike offer sweeping views, crisp mountain air, and plenty of wildflowers in mid to late summer.
Mirror Lake Trail
Distance: 2 to 5 miles round trip depending on route
Best for: Easy access, shaded path, and water views
Starting near the Happy Isles shuttle stop, this mostly flat trail winds through a shaded canyon and ends at what remains of Mirror Lake. While the lake itself dries up later in the summer, the tree-lined path and scenic views of Half Dome provide a peaceful and relatively cool hiking experience.
Mariposa Grove of Giant Sequoias
Distance: Varies by trail
Best for: Deep shade under giant trees
Walking among the giant sequoias is always a magical experience, and a smart one on a hot day. The towering trees offer plenty of shade, and trails like the Grizzly Giant Loop or Guardians Loop let you experience the grove without overexerting in the heat. Tip: Visit in the morning or late afternoon for even cooler temps and softer lighting.

Bridalveil Fall Trail
Distance: 0.5 miles round trip
Best for: Quick cool-down stop
This short, paved trail leads to the base of Bridalveil Fall and is a great way to feel the cool mist of a waterfall with minimal effort. It’s ideal if you’re short on time or traveling with kids, and a perfect stop during a warm afternoon in the Valley.
Cool Tips for Hot Days in Yosemite
- Start early: Begin your hikes before 9 a.m. to beat the heat and the crowds
- Stay hydrated: Carry more water than you think you need and refill at designated stations
- Dress smart: Light-colored, moisture-wicking clothing, a wide-brimmed hat, and sunscreen are essential
- Rest often: Find shaded spots to take breaks, especially during steep climbs
- Know your limits: The elevation and heat can take a toll, so listen to your body and don’t push too hard
Cool Adventures Await
Yosemite is full of surprises, and with a bit of planning, summer hikes can still be spectacular, even when the temperatures rise. Whether you’re misted by waterfalls, shaded by ancient sequoias, or exploring alpine meadows, there’s no shortage of cool trails to enjoy in Yosemite.
