Landing Zones

Thousand Footer

  • Failry large knoll  
  • Gate and fire road to access LZ and a few oak trees on far northern end
  • Advisable to check landing conditions prior to heading to launch; and mount a windsock or directional device towards middle of LZ.  Any wind indicator must be removed the same day
  • Turbulence is know to occur even in light wind

Mitchell Canyon

  • Located at end of Mitchell Canyon Road in Clayton, at entrance to park
  • Largest designated LZ at Mt. Diablo with few obstacles
  • Residential powerline opposite road on the westen edge of the field, and low tree line along creek bisecting LZ North-South
  • All wind flagging must be removed after each flight
  • Large plateau on eastern side of Mitchell Canyon LZ can be accessed through footpath entrance to the park on Mount Tamalpais Drive
  • Typically this field is selected if westerly wind has developed at the lower altitudes after launching from the Tower
  • Turbulence from Mt. Zion quarry can be avoided by circling down over the Park lands east of Mitchell Canyon and then making a final approach in the smoother air over the LZ

Curry Point

  • Located approximately one mile down South Gate Road from the Midpoint Junction Ranger Station near the Curry Point Parking Area
  • Site is an uphill LZ favorable in SE to SW wind
  • This is a possible landing zone for the the South Launch
  • No significant obstacles, but pilots should be aware that LZ can be turbulent in NW/N winds
  • Helicopters may use the nearby landing pad on rare occasions

Macedo Ranch

  • Located east of Macedo Ranch Staging Area parking lot; above adjoining access path
  • Site is an uphill LZ at 700’MSL; 2,100′ vertical feet and a 6.3:1 glide from Jupiter launch
  • Vehicles access from Green Valley Road that crosses Stone Valley Road in Danville
  • There is a $6 fee to park here or you can park outside the park on Emmons Canyon Dr.

Lime Ridge (aka Blake’s)

  • Lime Ridge is just south of the Boundary Oak Golf Course, at the end of Valley Vista Road
  • LZ is outside of the State Park, and used by special WOR agreement with the City of Walnut Creek
  • This LZ is an alternative to the Thousand Footer when south-to-west winds are stronger, making the Thousand Footer a difficult landing site
  • A hillside LZ, Lime Ridge has no significant obstacles and is well removed from the access path
  • Public parking is available on Valley Vista Rd
  • Pilots sometimes meet here to Uber or carpool to launch

Closed LZs

Athenian School

  • On the south side of the park and sometimes used as rendezvous site by pilots

Morgan Territory
