The Bay Area Ridge Trail: El Sereno Loop offers a challenging yet incredibly rewarding jogging experience, characterized by its significant elevation changes and stunning panoramic views. You'll navigate wide dirt trails and fire roads, encountering steep, rocky sections that lead to expansive vistas of Lexington Reservoir, Silicon Valley, and the distant Diablo Range. Much of the route traverses exposed chaparral, but higher elevations reveal meadows and occasional shaded groves, providing a dynamic backdrop for your run.
Planning your visit requires a bit of foresight, especially if you're tackling this difficult 7.1-mile (11.4 km) route with its 1306 feet (398 metres) of elevation gain, which typically takes around 1 hour and 33 minutes. Due to the trail's exposed nature, an early morning start is advisable, particularly on hot days, to beat the sun and secure one of the limited parking spots at the Montevina Road trailhead. Remember to bring plenty of water and sun protection.
This segment of the Bay Area Ridge Trail, dedicated in 2021, is celebrated for its solitude and spectacular viewpoints, making it a standout among circular jogging routes in Santa Clara County. While it's a difficult trail best suited for experienced joggers, the payoff is an intimate connection with the South Bay's natural beauty and a chance to spot local wildlife like mule deer and coyotes.
