El Dorado County, located in east-central California, encompasses 1,805 square miles of rolling hills and mountainous terrain.
The County’s western boundary contains part of Folsom Lake, and the eastern boundary is also the California-Nevada State line. The County is topographically divided into two zones. The northeast corner of the County is in the Lake Tahoe basin, while the remainder of the County is in the “western slope,” the area west of Echo Summit. This landscape invites residents and tourists alike to enjoy outdoor recreation activities year-round.
