Further upstream and higher in elevation, the watershed is mostly mixed coniferous forest (pines and firs). The largest concentrations of giant sequoias, which grow only on the western slope of the Sierra Nevada, are found in this section of the Kaweah watershed at mean elevations of , although specimens have been found as low as . The Kaweah watershed includes Giant Forest, the most visited and accessible of all the sequoia groves, located on the divide between the Middle and Marble Forks; it includes the General Sherman Tree, the largest tree in the world by volume. Redwood Mountain Grove, the largest sequoia grove in the world at , and 21 other groves are also located in the Kaweah watershed. A relatively small portion of the Kaweah basin is high, craggy alpine country typical of the southern Sierra; such treeless, lake-studded areas of exposed granite are mostly found along the crest of the Great Western Divide.
