Hiddenbrooke Golf Club sits in the rolling hills northeast of Vallejo, California, where the terrain transitions from the flatlands of the North Bay toward the interior valleys. Designed by Arnold Palmer and Ed Seay and opened in the late 1990s, the course was developed as the centerpiece of a residential community. The design takes advantage of the property's natural elevation changes and oak-studded hillsides, creating a layout that moves through varied topography characteristic of this part of Solano County. The routing incorporates the site's native landscape, with fairways that bend around mature oaks and play across gentle to moderate slopes. Water features come into play on several holes, and the design emphasizes strategic positioning off the tee to set up approach shots to greens that are often elevated or contoured. The Palmer-Seay collaboration here reflects their approach of creating courses that balance playability for resort and residential golfers with enough challenge to maintain interest for regular play. As a semi-private facility serving both members and daily-fee players, Hiddenbrooke functions as a community amenity while also welcoming outside guests. The course provides a golf option in the North Bay region between Napa Valley to the west and the Sacramento area to the east, offering a setting that feels removed from urban surroundings despite its proximity to Interstate 80 and the greater Bay Area.
