JOHN MUIR TRAIL
INYO AND SIERRA NATIONAL FORESTS
Yosemite National Parks

The John Muir Trail extends 221 miles along the crest of the Sierra Nevada Range through the Inyo and Sierra National Forests and Yosemite National Parks. It's named after the famous naturalist-conservationist, John Muir. This is real backcountry hiking as it can take 30 days or more to do the entire trip from Lone Pine Mt. Whitney to Yosemite. It's remote, it's long, and it's going to be a challenge!
TRAIL SUMMARY
TRAILHEAD ELEVATION - 10,000 at Yosemite
HIGHEST ELEVATION - 14,496 at Mt. Whitney
TRAIL DIFFICULTY - Strenuous and at high altitudes.
SEASON - Warm summer days, Freezing temperatures can occur at any time. Snow may be present in July.
TRAILHEAD
If you are driving, the southern trailhead is just west of the town
of Lone Pine, about 3 hours north of Los Angeles on Hwy 395. The
northern trailhead is in Yosemite Valley, which can be reached from
the west via Hwys. 120 or 140; on the east side of the Sierras,
from Hwy 395 at Lee Vining via Hwy 120 over Tioga Pass. The John
Muir Trail officially begins at Happy Isles in Yosemite
the north end, and ends on the summit of Mt. Whitney. It is recommended
to start at Yosemite, which is lower and work your way up, which
will help you get acclimated to the high altitudes. Obtaining a
Yosemite wilderness permit may be easier than obtaining a permit
to begin your trip at
Mt.
Whitney, as many people wish to climb Mt. Whitney and you must
compete with them for permits. There are many other possible entry
trails along the way that will shorten the trip and provide easy
access. Contact the appropriate Ranger Station for more information.
You need to plan your trip for this is the mother of all trails.
It is not a day hike!
The most popular time to travel the John Muir Trail is July through
October. Snow may be present on high ridges and passes in early July.
Most of the trail is at elevations above 7000 ft. and in some places
over 13,000 ft. Summer days are usually warm, but freezing temperatures
may occur at any time. Snow usually covers the trail in November.
WILDERNESS PERMITS
A wilderness
permit is required for any overnight stay in Wilderness or National
Park backcountry areas. During the summer season, quotas are in
effect on popular trails to minimize backcountry impacts and provide
a quality wilderness experience for all visitors. Plan your trip
early. Contact the Ranger Station nearest your entry point for further
information on obtaining your wilderness permit.
WOOD FIRES/CAMPSTOVES
Wood fires are prohibited in some
areas due to fire danger and the scarcity of dead and down wood.
In areas where fires are allowed, dead and down wood may be scarce
or too wet to burn. Never cut down standing trees or branches off
of standing trees. Please use existing campfire rings and make small
fires to conserve available firewood. Extinguish fires with water,
stirring until cold; never pour dirt on your fire as this rapidly
fills the campfire ring. Camp stoves are strongly recommended.
CAMPSITES
Camp on mineral soil, never on vegetation. Terrain
permitting, locate your camp at least 100ft from water and trails,
never closer than 25ft. Pick a place where you won't have to clear
vegetation, level a tent site or trench around your tent. Before
leaving camp try to make the site look as if no one had been there.
Your example may catch on!
BEARS
Bears are present in many
areas of the John Muir Trail. Improper food storage often results
in bears eating food that is bad for them, and a hungry hike out
to the nearest trailhead for the ill-prepared hiker. Bear-proof
food storage lockers have been placed at some locations along the
trail. Park regulations require that food be hung using the counter-balance
method or stored in one of the lockers provided. A 50ft length of
nylon cord must be carried for this purpose.
WATER
Surface water is common along the trail, but open
water sources are easily contaminated. Boil, filter or chemically
treat all drinking water. Water is contaminated by improper human-waste
disposal. Bury human-waste at least 100 ft. from water and wet areas
and burn or pack out all toilet paper.
SAFETY
The mountainous backcountry environment presents
many hazards not commonly encountered in our daily lives such as
bears and
mountain
lions. Enjoy the challenge of the wilderness but don't take
unnecessary risks. Be prepared and alert to changing trail and weather
conditions. Snowstorms can occur at any time of the year; warm,
waterproof clothing is a must for safe backcountry travel.
