Humans have travelled or lived in the Southern Sierra for at least 6-7,000 years. In the higher mountains, and also down into the western foothills, lived hunters and gatherers remembered today as the Monache or Western Mono. West of the Monache in the lowest foothills and also across the expanses of the Great Central Valley were a second group, the Yokuts.

In the late 1700s and early 1800s, Spanish began exploring the edge of the Sierras. Soon afterwards, trappers, sheepherders, miners, and loggers poured into the Sierras seeking to exploit whatever the mountains had to offer. By the end of the 19th century, San Joaquin Valley communities increasingly looked to the Sierras for water and recreation. In the struggle between all these competing interests, two national parks were created that became Sequoia and Kings Canyon National Parks. Today the parks protect 265 Native American archeological sites and 69 historic sites. Sequoia, as the nation's 2nd national park (1890) and the first of the California National Parks, is its own historic site.

Sequoia is named for its groves of Sequoia trees, the largest trees known, and Kings Canyon is named for the deep valley of the Kings River.

Extreme topographic differences and a striking elevation gradient (ranging from 1,360 feet (412 m) in the foothills to 14,494 feet (4,417 m) along the Sierran crest) create a rich tapestry of environments, from the hot, dry lowlands along the western boundary to the stark and snow-covered alpine high country.

This topographic diversity in turn supports over 1,200 species (and more than 1400 taxa, including subspecies and varieties) of vascular plants, which make up dozens of unique plant communities. These include not only the renowned groves of massive giant sequoia, but also vast tracts of montane forests, spectacular alpine habitats, and oak woodlands and chaparral.

The richness of the Sierran flora mirrors that of the state as a whole—of the nearly 6,000 species of vascular plants known to occur in California, over 20% of them can be found within Sequoia and Kings Canyon National Parks.

Sequoia and Kings Canyon National Parks support a wide diversity of animal species, reflecting the range in elevation, climate, and habitat variety here. Over 260 native vertebrate species are in the parks; numerous additional species may be present but have not been confirmed. Of the native vertebrates, five species are extirpated (extinct here), and over 150 are rare or uncommon.

There have been some studies of invertebrates here, but there is not enough information to know how many species occur in the parks. Many of the parks' caves contain invertebrates, some of which occur only in one cave and are known nowhere else in the world.

The closest commercial airports are Fresno Airport and Bakersfield. The nearest international airport is Los Angeles International Airport (LAX). All three offer car rentals. To reach Sequoia Park, take Greyhound to Visalia, then the Sequoia Shuttle to the park.

Fresno and Hanford are the closest cities with an Amtrak station, both served by the San Joaquins Oakland/Sacramento - Bakersfield route. Transfer to the Amtrak or KART county bus to Visalia for the Sequoia Shuttle to Sequoia National Park.

Greyhound stops in Fresno and Visalia. From Visalia, a $20 round trip shuttle^{[dead link]} goes to Sequoia National Park.

The parks are on the western slope of the Sierra Nevada, and can only be entered by car from the west. The two main entrances are:

• Route 180 east from Fresno. This enters the parks at Grant Grove and divides there to go either northeast to the main part of Kings Canyon or southeast to Sequoia. This is the recommended route from Northern California, and from Southern California if you intend to go directly to Kings Canyon.
• Route 198 northeast from Visalia. This enters Sequoia from the south, and is the recommended route from Southern California. This route is not recommended by the park for long vehicles such as RVs. On 12 a mile stretch from Potwisha Campground to Giant Forest Museum in Sequoia Park, advised maximum is 22 ft (6.7 m). Maximum length limit on the Generals Highway is 40 ft (12 m) for single vehicles, 50 ft (15 m) for vehicles plus a towed unit.

Both routes are winding mountain roads; driving speeds will be slower than usual and special conditions will apply in winter.

The Northern park entrance is somewhat more than an hour east of Fresno, with the park centers being another 45–60 minutes, and the total driving time from San Francisco should be close to five hours, and a little less from Los Angeles, using the Southern entrance. Those coming from the South may still prefer to enter the parks via the Northern entrance, since that route is less winding once you enter the parks. Larger vehicles such as RVs are not allowed from just inside the Southern entrance to Giant forest.

The Mineral Kings area is accessed via a separate road off Highway 198. Turn right in Three Rivers, before reaching the Ash Mountain park entrance. The road is single lane, and paved only part of the way.

Gasoline is not sold in the park, except the Grant Grove market which sells cans of emergency gas, so you should be careful to fill up at one of the towns on the way to the park or in the National Forest between Grant Grove and the rest of Kings Canyon.

The Eastern parts of the park are accessible from trailheads off Highway 395.

The Pacific Crest Trail (PCT) is a well-known trail that extends along the crest of the western alpine United States, from Mexico to Canada. It passes through California, Oregon, and Washington State.

Roads through both parks are at high altitude, and are generally slow and winding. Navigation is relatively straightforward: Route 198 is the main road through Sequoia, continuing from the Ash Mountain (southwest) entrance north through Sequoia's main sights (most of which are on signposted side roads) to intersect with route 180 at Grant Grove just inside the Big Stump (west) entrance, while Route 180 is the main road through Kings Canyon, continuing north and then east from Grant Grove to the main Cedar Grove area of Kings Canyon. Parking is generally ample at most sights in the park.

Sequoia National Park provides a free in-park shuttle. There is no public transportation in Kings Canyon National Park.

The High Sierra is a backpackers' paradise, and numerous trails wind through Kings Canyon and branch out from Mineral King. Permits are required and may be requested on a first-come, first-served basis at the ranger station nearest the trailhead that is going to be used. Permits are issued the morning of the backpacking trip or after 1PM the day before the trip. The cost of a permit between mid-May and late September is $15 per group. Permits are free the remainder of the year. There is a quota for each trailhead and when it is reached, no more permits are issued for that day. Popular areas may fill well in advance during the summer, so reservations are recommended and can be made after March 1 by faxing in a form (available from www.nps.gov/seki/resform.htm) no later than three weeks prior to the planned start date.

Do not feed or touch any of the wildlife as there is the possibility of acquiring the plague from fleas that live on the animals. Be aware of rattlesnakes and always check where you are stepping.

Cougars (or "mountain lions") also inhabit the park, but are rarely seen. They look like light brown house cats, but 5–8 feet long (including the tail). In the unlikely event that you run into one, don't approach it, and don't run. A cougar expects prey to flee and will react appropriately. Pick up any small children or pets. Make eye contact, spread your arms to make yourself look bigger, and back away slowly. If it approaches you, make noise and throw things at it; let it know that you're dangerous too. If it attacks, don't curl up defensively... fight back.

The park is prime habitat for black bears and it is very likely that you will see one. Stay a safe distance from bears and be careful never to come between a mother bear and her cub. Never leave food in your vehicle or unattended at a camp site. Bear-proof containers are provided for food storage at camp sites and trail heads. Safely storing food is required by park regulations and is essential for your own safety and also for the ultimate well-being of the bears. You can find more information on bears in the park, how to deal with a bear-human encounter, and park regulations about bears at the National Park Service web site.

Ticks are prevalent in the park and may carry Lyme disease. To avoid tick bites, tuck pants legs into socks and tuck shirts into your pants. If you do find an attached tick, remove it carefully with tweezers and seek medical advice from a ranger or a doctor. If bringing your dog along, make sure to check the dog for ticks after your visit as well.

Poison oak is also present at elevations up to 5000 feet (1,500 m) in the park. It causes itching, burning rashes in the affected areas and is easily spread. Most trailheads have a bulletin board with a picture of poison oak. If you come in contact with poison oak, wash your clothes and the affected areas immediately. A product named Technu (found in camping stores and drugstores) is good for neutralizing the toxic oils from the plant. Avoid contact with your eyes.

Water from natural sources should be treated or boiled before drinking as it may contain giardia, a protozoa that causes intestinal illness.

Lightning can be a great hazard, especially on rock outcrops, on ridges or in meadows. If a storm approaches, try to get indoors or inside a vehicle. Do not stand under trees or in shallow caves.

Many of the roads in Sequoia and Kings Canyon National Parks are very steep. Use low gears when going downhill to avoid overheating and possible failure of the brakes. Slower traffic must use turnouts to let faster vehicles pass.

Especially in winter, roads can be snow-covered or icy. For up-to-date road conditions, call +1 559 565-3341 then press 9, then 4.

For 24-hour emergency towing, dial +1 559 565-3341, then press 0. In Sequoia NP, AAA service is available 24 hour for out-of-gas, lock outs, jump starts, and minor repairs. Call +1 559 565-4070.

Due to the remote nature of Sequoia and Kings Canyon National Parks, it is sometimes the site of illegal marijuana cultivation. If you come across a marijuana farm, immediately leave the area. Do not linger in the area of the farm as the people who plant the farms are often armed and do not take kindly to visitors. Report to park rangers as well as authorities immediately.
