Los Vaqueros Reservoir

Los Vaqueros Reservoir is an expanded reservoir to the north of Livermore. There are hike-able grounds around the lake, although these are sometimes closed for the bald eagles that occasionally settle in the area. The Los Vaqueros watershed comprises 19,300 acres (78 km²) of open space surrounding the 1,500-acre (6.1-km²) reservoir. Water is pumped into the reservoir from a Delta intake on Old River in the Sacramento-San Joaquin Delta when salinity is low, and used for drinking water when salinity in the Delta is too high. The Watershed also serves as a weather data collection site for Mallory Ridge weather station located at the top of the ridge above the Marina. The station has a remote access water station (RAWS), which is maintained by the Los Vaqueros Watershed Staff and linked to the National Fire Weather System. Other benefits of the reservoir include water storage for drought or emergencies, a protected open space, and recreation. There are 55 miles (89 km) of hiking trails in the watershed. The watershed is open for fishing, hiking and other activities year-round. Electric rental boats are available, but no outside boats can be launched on the lake. No swimming is allowed in the reservoir.

Brushy Peak Regional Preserve
Nature reserve with quintessential East Bay landscapes and animals like ground squirrels, lizards, birds, and even rare San Joaquin kit foxes. There are numerous trails into the hills in the park, although you will need special permission to get to the top of Brushy Peak. The West Side Loop Trail is a 2-mile (3-km) loop trail. The eastern side of the loop trail runs through a flat valley (part of Brushy Creek). The trail then turns west, steadily climbing a hill, before it turns south and nears the top of the 1,100 foot (340 m) peak. At this point, it begins to come back down the hill and returns to the staging area. The Brushy Peak Loop Trail is a 4.4-mile (7.1-km) loop that starts at the Laughlin Staging Area. The trail follows an old ranch road past several small ponds. The trail turns here, climbing the side of a hill which is covered in eucalyptus trees. The trail continues to rise, becoming a single track trail. It continues to climb through a region of scattered rocks. While reaching an elevation of 1,340 feet (410 m) over a distance of 2 miles (3.2 km), small oak trees are seen. The narrow trail then goes through a pass and winds down the west side of Brushy Peak. At this point, the trail turns south, winding along Brushy Creek until it reaches the West Side Trail. A collection of shorter trails dominate the southeast section of the park. These trails generally go around hills, reaching elevations of 700 feet (210 m) to 1,000 feet (300 m) over grasslands. Windmills can be seen from these trails. The southernmost trail in this region of the park, the Dyer Ranch Trail, connects with Laughlin Road near Springtown.

Lawrence Livermore National Laboratory
Lawrence Livermore National Laboratory is an American federal research facility, founded by the University of California, Berkeley in 1952. LLNL (Lawrence Livermore National Laboratory) conducts research into the properties and behavior of plutonium to learn how plutonium performs as it ages and how it behaves under high pressure. A Federally Funded Research and Development Center (FFRDC), it is primarily funded by the U.S. Department of Energy (DOE) and managed and operated by Lawrence Livermore National Security, LLC (LLNS). In 2012, the laboratory had the synthetic chemical element livermorium named after it. Access to Livermore Laboratory is limited. Most of the visitors are school students on field trips, who go to the Discovery Center.
