The Otay Valley Regional Park will represent one of the major open space areas within the southern area of San Diego County, linking south San Diego Bay with lower Otay Lake. It will provide South Bay residents and visitors recreational opportunities ranging from playing fields and picnic areas to hiking, biking, and horse trails. At the same time, the park will protect open space, wildlife, historic, agricultural, and archaeological resources.

With over 4,000 acres of open space, this Preserve is home to many rare and endangered plant and animal species. Visitors using the 37 miles of multi-use trails have the opportunity to pass through 14 different habitat types and view a waterfall.
The public can enjoy over three miles of mostly flat trails along the length of the canyon. More challenging hiking is available on the trails in several of the finger canyons leading up to the mesa tops. Biking is permitted on the maintenance roads in the canyon; no equestrian use is permitted. Major entries to the park are off Genesee Avenue and Regents Road where parking and picnic areas with restroom facilities are available.
