Berkeley sits on the east shore of San Francisco Bay in Alameda County, bordered by Oakland to the south, Albany and El Cerrito to the north, and the Berkeley Hills to the east. The city's economy and character revolve around UC Berkeley, with distinct commercial districts along Telegraph Avenue, Shattuck Avenue in downtown, and the Elmwood and Solano Avenue corridors. The flatlands stretch from the bay to the campus area, while neighborhoods like North Berkeley, Claremont, and the hills above Grizzly Peak offer residential areas that extend toward Tilden Park and the Caldecott Tunnel.
