I just completed my first Oakland Heritage Alliance tour. OHA volunteers lead tours through Oakland Neighborhoods most weekend days throughout the summer. The tour I participated in was through the Glenview neighborhood where I live. The guides had definitely done their research beforehand and provided a wealth of information about architects, builders, early dwellers, Dimond Park, Lions Pool, the Glenview shopping district, the now-closed Glenview Branch of the Oakland Public Library, PBPC, and on and on. I will definitely be attending future events.
Tours cost $10 for non-members $5 for members. Membership is $35/year for an individual or $50/year for a family. If you become a member the first tour is free.
