Editors' Suggestions

Competition for wilderness permits to hike on the John Muir Trail in Yosemite is very high. To reduce the impact on the trail, Yosemite has set up a 45 person per day exit quota over Donohue Pass. Only hikers with permits from a limited number of trailheads in Yosemite may then exit over Donohue Pass. The Lyell Canyon trailhead for this hike is one of those approved trailheads. Your permit will include passage out of the park over Donohue Pass. For more details, see Wilderness Permits for JMT Hikers

Increase the odds of obtaining a permit by planning your trip for September when fewer people are on the trail and mosquitoes are gone.

A 3-day trip will cover the trail at a comfortable pace and allow you to camp at such scenic spots at upper Lyell Canyon and Thousand Island Lake.

Remember that soon after Labor Day the shuttle bus from the Devils Postpile area to Mammoth Lakes is no longer running. Carry $7 for the fare.

Keep in Touch

Keep in touch with family and friends as you make your hike while increasing your safety. More and more hikers are carry a GPS satellite messaging device in case of an emergency on the trail or simply to reassure loved ones back home that all is well.


Wildlife

Notorious Yosemite bears won't be a problem as long as you use the required bear canister. Be especially vigilant about keeping food in your canister in Yosemite and around Thousand Island Lake. Deer are rare visitors along this heavily used trail, as are rattlesnakes.

Mosquitoes are especially annoying along Lyell Canyon in early summer. Plan your first night's camp in a dry and windy spot if you are hiking in July. By late August and through September they are usually not a problem.

Have your camera ready to snap a picture of a marmot on Donohue Pass. Birders will likely see Stellar Jays and Juncos. Unlikely sightings include Peregrine Falcons and Red-trailed Hawks.
