Green Valley serves as a primary point of settlement in this landscape of canyons and high ridges along the border of Napa and Solano Counties. The terrain is defined by a complex network of narrow valleys and high points, including Mt George and the Twin Sisters peaks. Significant water management is evident through several reservoirs and lakes such as Suisun Reservoir, Lake Curry, and Lake Frey. To the west, the slopes are crisscrossed by a dense network of recreational paths like the Bay Area Ridge Trail and Skyline Trail near Sugarloaf.
