Mt. Diablo

Last updated on August 11th, 2023 at 3:41 pm

Quick Overview:

Mount Diablo offers an excellent variety of soaring experiences to the advanced pilot. Pilots regularly soar Diablo’s shear rocky peaks, rolling hills and ridges, gnarly canyons and grassy pastures; sometimes all in the same flight.

As a site open only to USHPA advanced rated Hang Glider and Paraglider pilots, good flying skills and judgement are the keys to rewarding flights at Mount Diablo.

Note: Be certain you are familiar with site rules and meet all requirements before attempting to fly Mt. Diablo.

American Tower Launch

The RDS/American Tower launch site faces north northwest, and can be launched in light to moderate northeast to northwest winds. The launch is 3,600′ MSL and approximately 2900′ above the landing areas. The primary landing area is at the south-western end of Mitchell Canyon Road. Launches are steep drops from the edge of the level set-up area.

NOTE: Due to a separate Special Use Agreement with the American Tower owners, access is limited. To manage this sensitive relationship, only a limited number of local WOR pilots have been provided the combinations into the enclosed restricted area. To fly this site you must be escorted by one of these pilots. Please contact the Site Chairman, Robert Moore to reach one of these pilots. There is a 5 glider limit at this launch. Only one vehicle at a time is allowed in the area.

CAUTION: In strong north or northwest winds, it may not be possible to make it to the Mitchell Canyon landing area.

Landing Zones

Please see the site procedures for details.

The primary landing zones are 1000 Footer and Mitchell Canyon.

1000 Footer: Located on Northgate Road at the 1000′ elevation. Often considered the most technically challenging designated LZ, It is also the closest to the Juniper launch. A moderately sloping hill allows uphill landings in SW and W directions.

Mitchell Canyon: Located at the end of Mitchell Canyon Road in Clayton, this LZ is one of the easiest designated LZs. A gently sloping field allows uphill landings in N,NW,W and SW directions. It is a 6:1 glide from the American Towers launch.

There are a variety of other alternate / bailout / emergency Landing Zones designated.  Additional information is in the Site Procedures.

LZ Characteristics
Macedo Ranch Located at the end of Green Valley Road in Alamo, this LZ provides excellent landing approaches to a tall hill. Moderate hillside slopes allow uphill landings in N,NW,WNW and NE directions. See site procedures for more details.
Athenian School CURRENTLY CLOSED Located at the beginning of Southgate road in Danville, this LZ requires a relatively short final approach to a moderately sloping hillside. Landings are in the N to WNW direction. See site procedures for more details.
Curry Point Located along Southgate Road, this seldon-used LZ provides an effective bail out for pilots who misjudge the glide to Blackhawk Ridge. This is a technically challenging LZ, with a final approach heading south to land on a small hill at 1800 feet. See site procedures for further details.
Morgan Territory This is a rarely used LZ that is valuable to pilots attempting to soar North Peak. Located on Morgan Territory Road at the eastern base of North Peak, this LZ consists of a moderately sloped hillside allowing a westerly approach and landing at 800 feet. See site procedures for further details.

The common radio frequency is 147.405 Mhz and should be used for safety and logistics with respect to other pilots and non-pilots as this is a simplex frequency that is available to all ham radio users.

Use the common radio frequency to alert other pilots of any related to a possible accident or imminent EMS situation.

Visiting Pilots

Flying Mt. Diablo as a visiting pilot requires you have an advanced rating (H4/P4 or IPPI-4 or above), you must be a current USHPA member, and you must get a site introduction from a member of the Site Committee so you can sign the waiver, sign in, and given a comprehensive introduction. Please contact the Site Committee Chair for additional information.
