Welcome to Calero County Park, one of Santa Clara County's most diverse regional park and recreation areas. Once part of the Pueblo lands of San Jose, and Rancho San Vincente land grant, 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.

CATCH AND RELEASE... PLEASE DON'T EAT THE FISH
Mercury has been found to accumulate in Calero Reservoir at levels that make the fish from Calero Reservoir unsafe to eat.
The nearby Almaden Valley area of Santa Clara County was once the site of quicksilver (mercury) mining. Sediments containing mercury have been deposited in some of the local reservoirs. Over time, the mercury in the sediment may have been converted to methyl mercury by naturally occurring bacteria. Methyl mercury is absorbed by aquatic plants and fish, and subsequently by humans who may eat the contaminated fish. If you have any questions regarding mercury and its effects, please contact the County's Environmental Health Services, (408) 918-3400
Hours and Fees
The park is open year-round from 8 a.m. until sunset. The reservoir use hours are 8 a.m. until 30 minutes before sunset. Reservoir and vehicle use fees are collected daily. Launch and entry fees are posted at the kiosk. There is no fee for parking at the trailhead staging area.
