In coastal North County, the most extensive network of equestrian properties and trails would be in the Rancho Santa Fe and Olivenhain communities. There are also some equestrian homes and trails in Bonsall and Fallbrook. With our mild San Diego climate, it is horse heaven!
If you are looking for horse property with access to riding trails in the north county area then I would say Bonsall, with Fallbrook being a very close second. It is absolutly beautiful, defenitly has the small town country feel yet you are close to all!
