Current Road Construction — Impacts Begin August 17 on Mineral King Road

Mineral King Road (2025 - 2027)

Mineral King Road is a narrow, curvy mountain road that enters the Mineral King area of Sequoia National Park. The Mineral King area begins 9.4 miles (15.1 km) or a 45-minute drive above its junction with Highway 198, just before Lookout Point.

There will be occasional road construction on Mineral King Road during the late summer and early fall. During active construction, there will be road closures and traffic delays. Visitors will have to pass through the road construction to access the Mineral King area. Within the construction zone, active construction sites may move from day to day. At times, some campgrounds, trailheads, or private inholdings (such as Silver City Resort), may be in the construction zone.

This construction is within the Mineral King area, separate from the main areas of Sequoia National Park. Any closures and delays in this area will not affect visitors going through the main Sequoia National Park Entrance near Three Rivers, CA.
