Dog Mountain

Download Waiver

Located near Morton and Glenoma, WA,Dog Mountain is probably the most used hang gliding site in western Washington and it’s no wonder given the spectacular views of Mt. Rainier, Mt. Adams and Mt. St. Helens from above launch, and the consistently soarable conditions throughout the year. Dog Mountain is a USHPA-insured site, and all pilots must be current USHPA members to fly it. Additionally, the landowner maintains a locked gate at the bottom of the access road, and pilots must obtain a key and sign a waiver each year. Dog Mountain is H-2 friendly, especially now that the landing zone is accessible year round, but novice pilots must be accompanied by a H-3 or higher rated pilot who can explain site protocol and potential hazards. Dog Mountain is the Cloudbase Country Club’s “home” site and many pilots spend their weekend there with kids and dogs and all the outdoor toys, camping near the landing zone a.k.a “Dogpatch” when the lake is low enough, and sharing tales around the driftwood bonfire.

Paragliders rated USHPA P-3 and higher are welcome after signing a waiver. However, launch is difficult for paragliders due to extremely restricted launch space and abrupt grade change behind the short and steep launch faces. No Paraglider tandems.

When H-2 flights are in progress, Pilots are required to yield the appropriate soaring face to the H2s and stay out of their way.

Spring, Fall, Summer, Winter.


Gravel, 2WD, locked gate at bottom, road has one narrow and dangerous curve on cliff face. While environmental mitigation is in progress on the lake bed, parking and vehicular access will be restricted to the roadside parking lot and no camping is permitted.

    Only launch within your rating and skill levels; When in doubt, don’t set up or launch.

    If you’re in the air and the sky starts to look threatening, get out of the air immediately. Also be aware of nearby terrain and potential for rotor. (Yes this is common sense H1/P1 stuff and we feel silly for needing to say it, but rest assured it’s here for a reason!).

    All incidents should be documented via the current USHPA incident reporting protocols with a courtesy copy to the site contact. Any incident involving non-pilot property damage, injuries or assistance from non-pilots(EMS, police, public bystanders etc) must also be reported as soon as practical to the site contact.

    In an emergency, Call 9-1-1 first.
