St Helena

DSCN1177

Location: 7 mi NNW of Calistoga. Robert Louis Stevenson State Park. DeLorme 83 C7

Elevation: Launch 4,000 ft, top of mountain 4,343 ft MSL.

Launch:  Steep launch, faces SW.  Good in light winds, which are common.
Setup area is steep and rocky.
Park vehicles on State Park property, just east of road to towers.

Season:  Spring and fall.  Thermals in the summer are weak and rough, seldom flown then.

Ratings: H4/P4, H3/P3 if sponsored by SW.
Pilots must be current USHPA (United States Hang Gliding and Paragliding Assn.) members.
Pilots must be members of Sonoma Wings, or be a sponsored guest. Sponsors must be H4/P4 Sonoma Wings members, are responsible for their guests, and for ensuring that they are familiar with the rules.

Speed wings are prohibited.

Cautions: Locked gate on road to launch, 6:1 glide out; vineyards abound.
There are few safe places to land on the way out to Knights Valley, so don’t get low on the mountain.
Bailout LZs, such as they are, are for emergency use only.

Speed wings are prohibited.

Flying: In summer the marine airmass usually dominates, so soaring conditions are not good here at this time.
Best times are spring and sometimes in the fall.
5,000 – 6,000ft MSL is typical over the mountain, 7000 is good, 8000 is the record. Over the back, 11,000ft at Crazy Creek.
Thermals can be rough over the big rocks at the North Peak.
Early in the year, the valley and LZ can be very good and smoother than the top.
XC south down the Napa Valley is possible but not recommended because of the scarcity of LZs.
Pope Valley is a better route to Lake Berryessa and the Blue Ridge.
The record is over 100 miles to the eastern Central Valley, watch out for restricted airspace near Travis, Sacramento, etc.

Landing: Large field in Knights Valley, privately owned.
We are VERY lucky to be able to use this field – everywhere else is vineyards.
Gate is usually locked – do NOT climb OVER gates or fences.
There are usually cows, and some bulls, in this field. Not a problem when landing but can be a nusiance when breaking down.
Conditions are usually light winds out of the W or NW
The LZ can be floaty so land a ways out there.
Spring winds can sometimes be strong and turbulent, especially on the ground. Watch out for wires and turbulence from trees.
