      "This approximate 4,471 acre park is nestled in the eastern foothills of the Santa Cruz Mountains. Two distinct areas define this park: the reservoir, which offers a host of water-oriented recreational activities, and the adjoining "back country" which reveals to the visitor California Oak woodland, chaparral, riparian plant communities and associated wildlife habitats. During the months of March, April and May the "back country" offers a spectacular display of wildflowers. In addition, the park offers breathtaking views of southern Santa Clara County and the surrounding Santa Cruz Mountain Range. Enjoy your visit today, and return again to experience the diversity of Calero County Park. " - Calero Website
