TheGiant Forest, famed for itsgiant sequoia trees, is within the United States'Sequoia National Park. Thismontane forest, situated at over 6,000 ft (1,800 m)above mean sea level in the westernSierra Nevada ofCalifornia, covers an area of 1,880 acres (7.6 km2). The Giant Forest is the most accessible of allgiant sequoia groves, as it has over 40 mi (64 km) ofhikingtrails.
Five of the ten most massive trees on Earth are located within the Giant Forest. The largest of these, theGeneral Sherman Tree, measures 36.5 ft (11.1 m) across the base. The giant sequoia is the world's most massive species of tree and is one of the six species documented to grow to 300 ft (91 m) in height; the others arecoast redwood,yellow meranti,Eucalyptus regnans,Douglas fir, andSitka spruce. It is also among thelongest-lived of all trees in the world.

Giant Forest is close toCrystal Cave,Moro Rock andCrescent Meadow.
The western trailhead of theHigh Sierra Trail which crosses the Sierra Nevada toMount Whitney is at the Crescent Meadow parking area.
Ponderosa,Jeffrey,Sugar, andLodgepolepine trees are common here, as well aswhite andred fir. Visitors often seemule deer,Douglas squirrel, andAmerican black bear. TheNational Park Service warns visitors not to leave any food in unattended vehicles because bears may break in to steal food.
Giant Forest is unique among sequoia groves in that it contains large water-storingfen meadows such as Round Meadow, Crescent Meadow and Circle Meadow.
Thegiant sequoia trees are first encountered on the approach from the south at Giant Forest Village—a small cluster of buildings that is dwarfed by the surrounding trees. Some of the sequoias have become unstable due to root damage caused by building development and hence visitor services in this area have been reduced, including transfer of lodging to Wuksachi Village, 7 miles (11 km) north. The sequoia forest extends mainly east of the village, and is accessed by a three-mile (4.8 km) side road plus many interconnecting foot trails. These range from one to five miles (1.6 to 8.0 km) in length, leading to various named individual trees and clusters of particular importance. The area is generally quite sheltered and receives high rainfall, which is one reason why the sequoia attain such size, but these conditions are also ideal for mosquitoes, which are abundant in the forests most of the year. These provide the only real hazard—the paths are generally quite level and well shaded from the sun.
Once the home of nearly 300 buildings, the region now has four, with no commercial activity. It is a designated "day use" area. TheGiant Forest Lodge Historic District was designated in 1978, encompassing the main area of development in the Giant Forest grove. The development was demolished between 1995 and 2000, with day use features moving to the nearbyGiant Forest Village–Camp Kaweah Historic District, which was itself extensively altered, and overnight visitor services moving to Wuksachi Village. The area within the grove was restored to nearly natural conditions, allowing the use of fire for forest management and the germination of new sequoia seedlings.
The forest can be reached fromFresno byState Route 180 or fromVisalia byState Route 198. TheGenerals' Highway connects Giant Forest toKings Canyon National Park and theGeneral Grant Grove, home to theGeneral Grant tree among other giant sequoias.

Some of the trees found in the grove that are worthy of special note are:
