Crestwood Summit

Crestwood Summit is a pass through the Cuyamaca Mountains of southeastern San Diego County, California, traversed by Interstate 8. Its altitude is 4,190 feet (1,280 m) westbound, and 4,181 feet (1,274 m) eastbound. Together with Laguna Summit to the west and the Tecate Divide to the east, it forms the highest of the three high points of Interstate 8 as it passes through the Cuyamaca Mountains.

The reservation of the La Posta Band of Diegueno Mission Indians spans the summit, and the band maintained the La Posta casino at the summit until its closure in 2012.
