San Diego Canyon

San Diego Canyon refers to the numerous natural valleys and ravines scattered throughout San Diego County, formed by natural water flow and erosion over time. These canyons often contain diverse plant and animal habitats, contribute to local waterways, and influence the region’s topography and climate. Many are preserved as parks or open spaces for recreation and wildlife conservation, offering scenic landscapes and outdoor activities. They are important ecological features that support biodiversity, improve air quality, and provide natural drainage in the urban landscape. Examples include Mission Gorge, Cowles Mountain, and Los Penasquitos Canyon.
