Before this 222 acres (90 ha) park became a protected area, it was home to wheat fields, the site of Ranchos and railroad stations for a railroad that ran from Oakland to Orinda through Berkeley and Richmond via El Sobrante. It was originally part of the 17,754-acre Rancho San Pablo. Francisco Castro acquired the rancho in 1823, and the grove later became the Clancy Ranch. By 1886 the railroad had scheduled stops from the California and Nevada railroad at Laurel Glen and Frenchman's Curve. The picnic areas around the park are named after some of the former railroad stops. The eucalyptus trees were planted in 1910. This park was named in honor of President John F. Kennedy and opened on October 22, 1967. It is now owned/operated by the East Bay Regional Park District(EBRPD).^[2]

There are several trails located within the recreation area ranging from very easy to somewhat difficult. All trails lead out from the eucalyptus grove located near the base of the San Pablo Dam, adjacent to the parking area. Several trails will guide visitors through changing landscapes of native Oak chaparrals and fern laden Bay laurel woodlands. A segment of the Bay Area Ridge Trail begins at Kennedy Grove and runs along the western shore of San Pablo Reservoir. Eventually the trail crosses San Pablo Dam Road and then climbs up the San Pablo Ridge. *NOTE* An EBMUD permit is required for this hike.

Seen from the Kennedy Grove area is the San Pablo Reservoir where fishing is popular. The reservoir has trout and catfish and is recognized as one of the finest fisheries in the East Bay. However a fishing license and EBMUD fishing permit is required. You can see flocks of ducks, shorebirds, geese, and white pelicans from the trails. Sometimes deer, bobcats, foxes and coyotes can be sighted. There are also species like quail, dove, and wild turkeys. Some birds of prey that are known to take the skies above Kennedy Grove are eagles, owls, hawks, and ospreys.^[3]

The area surrounding San Pablo Dam is fairly temperate. The East Bay is warmer than the Peninsula. Summer temperatures tend to vary from 60 to 100 degrees. Fog is very common. Rainfall occurs mostly during the months of October through March. The temperatures can dip below 32 degrees in the winter.^[4]

Popular activities include hiking, day camps, bird watching, walking around the lawn asphalt path and special events such as cross-country meets. The eucalyptus grove is frequently used as a desirable setting for company picnics, family reunions and other group events.
