Learn About Edgewood Park and Natural Preserve
Edgewood Park and Natural Preserve has something for everyone. We are San Mateo County’s only natural preserve with extraordinary biodiversity and over ten miles of trails in just 467 acres. Minutes from downtown Redwood City, Edgewood includes precious native grasslands, oak woodlands, and chaparral habitats. The main ridge in the center of the preserve, known as Inspiration Heights, rises 800 feet in elevation, where hikers are rewarded with spectacular views of Skyline Ridge, Huddart Park, the San Andreas Fault Zone, Crystal Springs Reservoir, and the San Francisco Bay. Check out this short video from Bay Area Bountiful to learn more about what makes Edgewood special.
Nature Walks and Hikes
Each spring, join a Friends of Edgewood docent for a guided Wildflower Hike. Free hikes are typically offered March through May. When hikes are scheduled, reserve your ticket at friendsofedgewood.eventbrite.

General online tools for identifying plants and animals
- Seek by iNaturalist – This easy-to-use app helps you identify just about any life form. Just open the app and point your camera (you don’t even have to take a photo!). Or, open a photo you’ve already taken. Unlike iNaturalist, this app doesn’t require an account or collect data (like your location), so it is only used to identify things, not to contribute to citizen science, and is kid-friendly. This app fully downloads to your device, so you can use it offline.
- iNaturalist – Use this app and/or website to explore and share observations of all life forms. You can browse data without an account, but to post observations, you need to create a free account. You can get identification suggestions, and upload and track all of your observations. The app does not fully download to your device, so you cannot use it offline.
- For apps and/or websites specific to birds and plants, see those Field Guides.
