It’s actually amazing Gonzales Canyon exists. It’s located right in the middle of suburban North County. There isn’t a lot of open space in the area due to multimillion-dollar homes built. It’s a desirable area, so there are far more homes than open space.
If you live in the area, you are lucky to be so close to such a wide array of trails.
If you’ve been to San Diego, you know Torrey Pines State Natural Reserve is one of the best parks around. It’s over 1500 acres of unspoiled beaches, animals, plants, and even a lagoon. It does get fairly busy, so I recommend coming early.
