The Sierra Nevada region of California is its alpine region, covering a large portion of the state's inland territory. Rugged mountains and awe-inspiring canyons in the area's national parks and forests are truly part of the United States' national wilderness treasures.

It's a region of grandiose sizes; Mount Whitney, the highest peak in the contiguous U.S., is here, as well as the giant sequoias, the largest living things on earth. The human population, however, is relatively small. Most of the towns and cities in the Sierra Nevada region are ski resort towns, or gateways to the area's parks.

Regions[edit]

Counties[edit]

  Alpine County
Sparsely populated Alpine County advertises itself with the slogan "two people per square mile and you", making it a good option for a quiet mountain getaway. Attractions include the hot spring pools at Grover Hot Springs State Park, amazing views of the Sierras from the Ebbetts Pass National Scenic Byway, and the excellent winter skiing at Kirkwood Mountain Resort.
  Calaveras County
Sparsely populated Calaveras County inspired author Mark Twain's first successful story "The Celebrated Jumping Frog of Calaveras County", and today visitors can both visit Twain's cabin and enjoy the annual Jumping Frog Jubilee in the tiny town of Angels Camp. The county is also home to several natural caves, a handful of wineries, Gold Rush history, and giant sequoia trees in Calaveras Big Trees State Park.
  El Dorado County
"El Dorado" is Spanish for "the gilded/golden", an appropriate name for the county where the California Gold Rush was kicked off after a discovery at Sutter's Mill (near Coloma) in 1848. The county's attractions include mountain scenery, gold mining history, the impossibly blue waters of Lake Tahoe, backpacking opportunities in the Desolation Wilderness, and epic skiing in the South Lake Tahoe area.
  Fresno County
Sprawling Fresno County is home to Fresno, California's fifth-largest city, and vast agricultural areas. The eastern side of the county is mountainous, featuring the remote wilderness of Kings Canyon National Park, which attracts visitors to its giant sequoias and unspoiled meadows that lie at the crest of the Sierra Nevada range.
  Inyo County
Inyo County is a land of extremes, covering a massive 10,000 square mile expanse of the Eastern Sierra and California Desert. Inyo County is home to Mount Whitney, the highest mountain in the lower-48 states, as well as Death Valley National Park, the largest national park in the lower-48 states and host to earth's hottest temperatures and the continent's lowest elevation. In addition, ancient bristlecone pine trees can be found within the White Mountains, the oldest of which is estimated to be around 5,000 years old.
  Kern County
Kern County extends across a number of geographic regions: the western portion is in the San Joaquin Valley, the northeastern portion is in the Sierra Nevada mountains, and the southeastern part is in the Desert. Visitors to the county are most likely to be heading to Bakersfield, one of California's largest cities, or traveling along Interstate 5 past oil fields and agricultural areas.
  Madera County
Madera County's agricultural western half offers plenty of hotels and amenities for travelers, while the mountainous eastern half features unspoiled Sierra Nevada wilderness that is home to portions of Yosemite National Park, the Ansel Adams Wilderness, and Devils Postpile National Monument with its impressive basalt columns and iconic Rainbow Falls. Be aware that there are no roads crossing the county from west to east, so it may be a very circuitous route for those who want to see everything Madera has to offer!
  Mariposa County
Mariposa was the largest county in California at the time of statehood in 1850, but later ceded land that formed twelve other counties. Today it maintains a relatively small footprint in the Sierra Nevada foothills, but has kept one of the state's treasures: Yosemite National Park, home to impossibly tall granite cliffs, remote alpine wilderness, and an iconic valley.
  Mono County
Remote and expansive Mono County is a destination for outdoor enthusiasts. It is the eastern gateway to Yosemite National Park, home to the Old West ghost town of Bodie, and Mammoth Lakes is a favorite winter skiing getaway. The gigantic Mono Lake is perhaps the county's premier attraction, a stopover for millions of migratory birds and thousands of tourists who explore its alkaline waters and bizarre tufa formations.
  Nevada County
Rising from the Sierra foothills to the Nevada border, this county retains many examples of its Gold Rush past, ranging from California's oldest operating theater in Nevada City to the Holbrooke Hotel in Grass Valley, an establishment that has hosted four Presidents since its opening in 1851. Even before the Gold Rush, the county gained fame for the ill-fated Donner Party of 1846, and today the lake named for that doomed expedition is a popular recreation spot.
  Placer County
Placer County stretches from the suburbs of Sacramento to Lake Tahoe and the Nevada border. Named after the Spanish word meaning "sand or gravel deposits containing gold", the county was a hotbed of activity during the Gold Rush. Today visitors can enjoy mountain activities such as hiking and skiing, and will also be impressed by the historic courthouse in Auburn.
  Tulare County
Tulare County is a region with two distinct personalities. The western half of the county lies within the agricultural Central Valley, offering rural landscapes as well as plenty of hotels and other amenities for travelers. The eastern portion of the county features the wilderness and high elevation of the Sierra Nevada range, including the largest trees on earth in Sequoia National Park, and the western slopes of Mount Whitney, the tallest mountain in the lower-48 states.
  Tuolumne County
Tuolumne County was one of California's original counties at the time of statehood, and today offers a glimpse into the region's gold mining and logging history, as well as numerous opportunities for outdoor recreation. Portions of Yosemite National Park lie in the county, and with limited parking and lodging inside of the park, the YARTS shuttle system makes the county's towns an option to consider for park visitors.

Understand[edit]

Location[edit]

The Sierra Nevada Mountains are located in eastern California. They stretch from the north of the state to the south, the southern ending being near Los Angeles. The southern parts of the Sierra Range include the highest mountains, such as Mount Whitney and Yosemite National Park. In the north, the mountains are generally not so high but scenery is just as dramatic - Lake Tahoe is towards the northern regions.

Climate[edit]

Silver Lake is located high in the Sierras, and can be covered with snow, even in summer

The region where the Sierras are located would be very hot, but the height at the top of the mountains (some peaks pass 14,000 feet) brings down the temperature significantly. Snow can come at almost any time of the year, and temperatures can change quickly.

The lower parts of the Sierra Mountains (in elevation) can be extremely hot, such as Auburn.

Get in[edit]

Several roads go into the Sierras, such as I-80 and US-50. These roads can close in winter, however.

Get around[edit]

Although roads such as the I-80 and US-50 make travel in parts of the mountains relatively easy, there are several things to consider when traveling in the Sierras:

Driving[edit]

  1. Many of the California state routes in the Sierras are closed in winter. Therefore, although they usually go far enough to reach major tourist sites and towns, they do not completely cross the mountains when winter closures come in. And even when the roads are open in winter, one is advised to bring chains. Even major roads like the I-80 have to close occasionally in bad weather.
  2. There are not many north-south roads. Nearly all roads cross the mountains east-west, since they connect populated areas, and are not primarily tourist routes. CA-49 is one of the few good north-south routes, although most north-south roads are twisty and slow due to the number of canyons they have to pass through. US-395 is a generally well-maintained north-south road that follows the Eastern Sierras through some sparsely populated but rather beautiful country, entering Nevada to serve Reno before heading back into California.
  3. A lot of California state highways go into the Sierras, but also end in the Sierras. For example, CA-203 goes west to Mammoth Lakes in the eastern Sierras and on to a pass of several thousand feet, but the road ends shortly after going over the pass, and does not go on to the Central Valley. Even worse, the CA-168 goes into the Sierras and reaches several thousand feet in elevation, comes to a dead end, only to start again on the other side of the mountains. There is no proper road connection between two parts of what seems to be the same highway.

Road Standards[edit]

Yes, traveling in the Sierras is much more difficult and requires more planning than most places. Generally, stick to state and national routes when possible - you can know two things with almost any California state routes:

  1. The road will be paved.
  2. The road will have two lanes at least, one for each direction. In some roads in the Sierras, passing roads also exist for short stretches.

Hiking[edit]

  1. Much of the Sierras is national parkland. This parkland has trails, and trail maps are often available in visitor centers. Trails will be of varying condition - trails in Yosemite Valley will be in much better condition than those on the edges of Kings Canyon, for example.
  2. For those who are ambitious, there are hiking trails in the Sierras which go hundreds of miles over mountain passes and canyons. Other trails are shorter, but still, most trails in the Sierras are pretty long and tedious.
  3. The Sierras are not like the community park down the road: these mountains are filled with bears and other wild animals. Although these animals will not usually attack you unless you attack them first, they are still extremely dangerous and may attack you if you have food items. Just the sight of a plastic bag can make a bear's mouth water. Even in regions of the Sierras near urban areas, bears can be spotted.
  4. The Sierras are a big place. In other words, you can get lost, and that's definitely no fun. As pine trees cover much of the land, landmarks might not be within view when you're in the middle of a forest. Make sure you stick to hiking trails and that you have a map with you.

Stay safe[edit]

What is winter?

On maps of the Sierra, some roads will be marked "Closed in winter." Travelers are often advised to "carry chains in winter." You might think that such advice refers to that time of year the rest of the world calls "winter" which lasts from Winter Solstice through Spring Equinox. You would be wrong.

What Californians are referring to is the time of year when it snows in the Sierra. Snow can begin as early as October, and last as late as May. Roads may be closed as late as July. When snow falls in mid October, it usually kills a few unprepared backpackers in the Sierra who hadn't carefully checked the weather reports. If you don't have chains during an early October or late May snowstorm, continuing to drive may kill you too.

The Sierras are a high mountain environment containing some of the snowiest places in the US. During winter you should always carry tire chains in your car and know how to use them.

When hiking or backpacking where you will be far from help, check the weather first. The first snows of Winter may come earlier than you expect.

In summer during the North American Monsoon, thunderstorms often build up near the crest of the Sierra Nevada, particularly during late afternoon. It is unwise to be in a high, treeless place during a thunderstorm. If hiking far in summer, it's a good idea to carry a light rain jacket just in case a thunderstorm pops up out of nowhere.

Bears are endemic to most parts of the Sierras, and unfortunately some of them have realized that humans are a source of delicious food and garbage and will wander into towns. If you are camping, be sure to research how to "bear-proof" your campsite. Note that it's not just food and food-related trash that attract bears, but anything with an attractive scent. E.g. toothpaste and even soap are surprising favorites. Bears almost never attack humans unless severely provoked, but there is a risk of getting between a mother bear and her cubs, which can provoke an aggressive reaction.

In general, don't feed or touch any wildlife. Any animal may bite if startled or frightened, and some carry nasty diseases including rabies and bubonic plague.

Go next[edit]

  • San Francisco is just a few hours west.
  • The Gold Country where the California Gold Rush began is in the Western foothills of the Sierra. There are plenty of quaint historic towns to visit there when traveling to or from points west.
  • If you're headed to Los Angeles or other places to the south, taking US 395 down the Eastern Sierra is a great scenic alternative to the monotony of traveling through California's Central Valley.
