Pilot comments
H4 or P4 rating required, contact Wings of Rogallo (www.wingsofrogallo.org) for site introduction and sticker. Also contact BAPA (https://www.sfbapa.org), who coordinates paragliding flights. There are two primary launches, and numerous LZs, but it is very important to only use designated launch/LZs. This site offers excellent flying, but it requires a thorough site introduction, and because it is in a sensitive State Park, the rules are important to preserve the site.
