Fodor's Expert Review Old St. Hilary's Landmark and John Thomas Howell Wildflower Preserve

The architectural centerpiece here is a stark-white 1888 Carpenter Gothic church that overlooks the town and the bay from its hillside perch. Surrounding the church, which was dedicated as a historical monument in 1959, is a wildflower preserve that's spectacular in May and June, when the rare Tiburon paintbrush and Tiburon black jewel flower bloom. Expect a steep walk uphill to reach the preserve. The Landmarks Society arranges guided tours by appointment. The hiking trails behind the landmark wind up to a peak that has views of the entire Bay Area.
