Diablo Pilots: No Landing Until Further Notice for the Athenian LZ

Athenian School has asked that we not land at the school.

Until further notice, please do no land there.

We will post any updates here.

Mt. Diablo

Last updated on September 25th, 2022 at 7:18 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.

Launches are steep drops from the edge of the level set-up area.

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.

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.

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.
