Takeoff description

The top Greylock is the highest point in Massachusetts. The mountain is a state park opening in the middle of May and closing late October. Greylock has a paved road to the top with a parking lot. There is a $2.00 fee for parking in this parking lot. There is also a lodge open to the public which has bathrooms, serves food and sells souvenirs. Please keep in mind that there could be a lot of non flying visitors to the park and respect should be given to them at all times. The park is also patrolled by a park ranger. Greylock rating is H4/P4 site. H3/P3 are allowed to fly there with a USHPA advanced observer, examiner or advancer instructor. The pilot observing must be present every time the H3/P3 launches. If you need an observer, please make arrangements with them prior to showing up. The pilot must sign in and show their current USHPA rating card at the front desk of the lodge. Pilot must sign a waiver the first time they fly Greylock every year. Pilot must also sign in every time that they fly there. Don’t forget your USHPA card. No card, no flying, no exceptions. Launch is located on the peak of the mountain facing southeast. The mountain can be flown in south to northeast conditions much of the time. Hang gliding set up area in the mowed grass area near the monument. The hang gliding launch is a short flat slope located just off the mowed grass area on the southeast side of the mountain. The paragliding launch is a large flat area above and behind the hang gliding launch on the mowed grass. Caution is needed when launching due the close proximity of the other winged pilot and the non flying public. After launching, be respectful of other pilots trying to launch and the viewing public. PLEASE NOTE: No top landing. Since top landing will put the site at risk for everyone, anyone caught top landing will permanently lose their right to fly Greylock.
