Eden Medical Center is the main acute‑care and trauma hospital serving Castro Valley and surrounding Southern Alameda County. Originally founded in 1954 by the Eden Health District, it has grown from a mid‑20th century community hospital into a modern, Sutter Health–affiliated facility with 130 private inpatient rooms, a Level II trauma center, and centers of excellence in neuroscience, orthopedics, stroke, cancer, rehabilitation, and women’s health. The original building was replaced in 2013 by a seven‑story, $320 million state‑of‑the‑art campus after a state‑mandated seismic retrofit and now offers around‑the‑clock emergency services, advanced imaging, birthing, and full inpatient care.

Lake Chabot is a scenic 315‑acre reservoir nestled in the Berkeley Hills, just east of Castro Valley. Constructed in 1874–75 on San Leandro Creek as a critical source of drinking water for the East Bay, it was originally known as the San Leandro Reservoir and remained closed to public access for nearly a century. In 1966, it was opened as part of the East Bay Regional Park District and has since become a beloved recreation spot offering fishing (stocked with trout, catfish, bass, and crappie), boating, hiking, biking and family outings—with amenities such as a marina, café, picnic sites, trails, and accessible launch facilities. The park is a vibrant outdoor haven with roughly 20 miles of trails for people to explore. Whether you're paddling, picnicking, or hiking along the peaceful lakeside, Lake Chabot combines rich history with natural beauty in Castro Valley.
