Sequoia and Kings Canyon National Parks
Although technically they are two separate national parks, Sequoia and Kings Canyon generally operate as a single unit in many ways. One fee (US $20 per person when entering on foot or by bicycle, US $30 for motorcycles, or US $35 per private vehicle) allows entrance to both parks.
The combined area of these two parks is 865,952 acres (3,504 km²) with most of that area being wilderness backcountry. The altitude in the parks range from 1,300 feet (418m) to 14,505 ft (4421 m). The front country area can be divided into basic areas: The Foothills, Giant Forest, Mineral King, Grant Grove, and Kings Canyon and Cedar Grove.
Humans have traveled 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 born that became what we know today as Sequoia and Kings Canyon National Parks. Today the parks together protect 265 Native American archeological sites and 69 historic sites.
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.
Flora and fauna
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 average temperature is 27.5 degrees Fahrenheit.
These lower elevations (Under 4,000 feet) are characterized by mild, wet winters and hot, dry summers. Precipitation usually occurs from January to mid-May; rain in the summer is rare. Average rainfall is about 26" (66 cm). During the winter, low-hanging clouds often drift in from the west, obscuring the countryside for several days at a time.
Summer in this forested area of the parks offers warm days and cool evenings. These elevations (4,000 - 7,000 feet) receive an average of 40-45" (102-114 cm) of precipitation annually. Much of this falls during the winter, resulting in a deep blanket of snow from December to May. Sub-zero temperatures, however, are rare. In the summer, occasional afternoon thundershowers may occur.
In fall and winter, Lodgepole Campground is generally 10-15 degrees F (6-9 degrees C) colder than the average middle-elevation temperature shown on the chart.
Summer temperatures in Cedar Grove are generally hotter than the average for the middle elevations, and cooler than the foothills. Temperatures in mid-summer may reach the 90's (35-40 degrees C). Cedar Grove is closed in the winter due to common rockfalls on the road.
The parks are relatively distant from major cities and airports, and there is no public transportation to the parks, although there is a $15 round trip shuttle from Visalia.
Fresno is also the closest city with an Amtrak station, and is served by the San Joaquins  Oakland - Bakersfield route. Visalia also has an Amtrak station that is connected to Sequoia National Park by a shuttle bus.
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:
Both of these 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 one 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 park entrance fee is $35 for private vehicles and $20 for individuals on foot or on bike, and is valid for seven days in both Sequoia and Kings Canyon National Parks. The National Parks pass ($80) allows unlimited entry into all national park areas for one year.
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.
Driving in the parks provide mostly up-close views of trees, so the roadside vista points that do exist should not be overlooked:
Some of the scenic attractions in Sequoia and Kings Canyon, divided by area, are:
A broad variety of wildlife can be seen in both parks, including deer, birds, and bears.
Sequoia and Kings Canyon both provide many trails for hiking and backpacking, and some facilities for horseback riding.
Suggested Day Hikes:
Most practical trailhead is Wolverton, just South of Lodgepole.
3.5 miles round-trip.
Especially attractive in the winter when the road to Cedar Grove is closed, as it affords a similar view.
Food and shops are available at Grant Grove, Lodgepole, and Cedar Grove visitor centers. Overnight visitors should consider buying some food in advance on the way to the park.
Lodging is available at the Wuksachi Lodge in the Lodgepole area (Sequoia), in the John Muir Lodge and the Grant Grove cabins at Grant Grove Village (Kings Canyon) and at the Cedar Grove Lodge in Cedar Grove (Kings Canyon). Reservations are recommended. Cedar Grove closes for the winter in October.
In addition, a range of hotels and motels are available outside the park, including several lodges in the National Forest (on the road from Grants Grove to Cedar Grove) and motels in Three Rivers (on Route 198 near the southwest entrance).
Camping is the most common way to stay in the park. There are campgrounds available in all areas of the park, although the ones closest to main attractions may require reservations at peak times. All campers should be aware of the presence of bears, and should stow any unattended food in bear-proof containers as instructed by park rangers.
Some Camp grounds outside the park that are within 10 mile:
1. Lake Kaweah Recreation Ground
2. Horse Creek Camp ground
3. Three Rivers Hide away
The High Sierra is a backpackers paradise, and numerous trails wind through Kings Canyon and branch out from Mineral King. In Kings Canyon, the Rae Lakes Loop  is particularly popular, while in Sequoia the High Sierra Trail and the Mineral King area  are popular. 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 1:00 p.m. 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.The entree fee is 5 to 10 dollars per private people.
There is no mobile reception inside the park. For all emergencies in Sequoia and Kings Canyon National Parks, dial 911 (toll free) from any phone.
Do not feed or touch any of the wildlife as there is the possibility of aquiring 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.
