Is the "Bay Tour" flight path documented, or is it a more informal route? Are there similar flight paths for other cities? During my Private Pilot's Licence days out in San Francisco, we often flew a "Bay Tour": a sightseeing flight northbound from San Jose through SFO's Class B , over the city and Golden Gate Bridge, then east to Oakland and south to return to SJC. Local approach controllers were familiar with this route, and a pilot could file a flight plan for a Bay Tour with everyone knowing what he was talking about. In addition, the tower at SFO would often go out of their way to give aircraft on a Bay Tour a better view of A380's and 787's out of SFO. However, I can't find any official information on it. Is it a published procedure, or just something that everyone out there has come to know about? Do similar flight plans exist for other cities and if so, where can I find information on them?
There certainly are similar routes - the Niagara Scenic Falls route, given in FAR 93.71 comes to mind.  (FAR 93 has plenty of these, by the way.)


  Comply with the following procedures when conducting flight over the
  area described in paragraph (a) of this section:
  
  (1) Fly a clockwise pattern;
  
  (2) Do not proceed north of the Rainbow Bridge;
  
  (3) Prior to joining the pattern, broadcast flight intentions on
  frequency 122.05 Mhz, giving altitude and position, and monitor the
  frequency while in the pattern;
  
  (4) Use the Niagara Falls airport altimeter setting. Contact Niagara
  Falls Airport Traffic Control Tower to obtain the current altimeter
  setting, to facilitate the exchange of traffic
  advisories/restrictions, and to reduce the risk of midair collisions
  between aircraft operating in the vicinity of the Falls. If the
  Control Tower is closed, use the appropriate Automatic Terminal
  Information Service (ATIS) Frequency;
  
  (5) Do not exceed 130 knots;
  
  (6) Anticipate heavy congestion of VFR traffic at or above 3,500 feet
  MSL; and
  
  (7) Use caution to avoid high-speed civil and military aircraft
  transiting the area to or from Niagara Falls Airport.
