King Range, National Conservation Area in Humboldt County, California, United States

The King Range is a mountain range of the Outer Northern California Coast Ranges, running parallel to the Pacific in Humboldt County, with western slopes falling steeply to the ocean. King Peak, its highest point, reaches 4,091 feet (1,247 m). Most of the range lies within the King Range National Conservation Area and the King Range Wilderness, managed by the Bureau of Land Management.

The Mattole and Sinkyone peoples lived in the King Range before the 19th century brought commercial logging, fishing, ranching and tanning. In 1936 and 1937 engineers routing State Route 1 north from Westport avoided the range's steep terrain and laid the road inland through Leggett, leaving the coast undeveloped. Congress designated 60,000 acres as the King Range National Conservation Area in 1970, added 42,585 acres as the King Range Wilderness in 2006, and in 2000 Bill Clinton designated the offshore rocks and islands as the California Coast National Monument.

The King Range was home to the Mattole and Sinkyone peoples before the 19th century brought commercial logging, fishing, ranching and tanning to the region. The range's name is not explained in the sources; the Mattole River, which drains it, carries the Mattole name.

Camping and overnight stays in the King Range National Conservation Area require a permit. The California Coastal Trail runs the length of the range, and mountain bike routes cross the protected area. Snow falls above 1,000 metres a few times a year, and the Mendocino Triple Junction makes earthquakes frequent.

The region is called California's Lost Coast because its rugged terrain made highway construction impractical, leaving the shoreline inaccessible by car. This geographical isolation accidentally preserved one of the state's last wild coastal stretches.
