• Before flying, pilots must sign-in on the sheet located in the sign-in box, which is at the foot of the Anniversary Trail, beside the trail sign at the upper parking lot.  Ask an administrator for the lockbox code.
  • Windy Hill Open Space Preserve hours are from sunrise to one half-hour after sunset. The lower parking lot is gated, and locks when the preserve closes.  Make sure your car doesn’t get locked in there.
  • Flying is prohibited on Independence Day, Memorial Day, and Labor Day, due to historically heavy park usage on these days.
  • When driving up to launch, Route 84 must be taken, rather than Old La Honda Road, in order to minimize residential traffic.  Old La Honda Road is a one-lane road for part of the way, and often has heavy bike traffic, particularly on weekends.
  • There can be no more than 10 gliders present in the preserve at any time, and no more than 5 at launch (HG + PG).
  • Tandem flights are prohibited, due to the long glide to the landing zone, and restricted landing field.
  • As of mid-2016, the MROSD has installed 2 gates through the launch area, to mitigate erosion on a bootleg trail. Pilots are allowed to temporarily take down the gates (clipped on with a carabiner) while launching. After the last pilot has launched, the gate must be put back up. Pilots must return to launch after flying to replace the gate.  Better yet, if any hikers, observers, or RC pilots are present, kindly ask them to replace the gate on your behalf after launching, to save yourself a trip back up to launch.
  • There is a 4000ft ceiling above Windy Hill from SFO’s Class B airspace. The airspace limit rises to 6000ft immediately south of Windy Hill Open Space Preserve. Ensure you look at a VFR map before flying, to familiarize yourself with the airspace.​​
  • After launching, and once some altitude has been gained from ridge lift near launch, fly away from the launch area. Gliders can be distracting to traffic along Skyline Blvd.
  • Do not fly low over the Sequoias seniors’ residence (immediately South of the LZ), Portola Road, or over any of the houses on the East side of the road.
