Takeoff description
Main launch sites: -'Eggli' (1650m): about 200 meters to the SE of the top of the cable car; - 'Hoernli' (1800m): on top of the mountain about 20 Minutes uphill. Both sites are easy and large enough for many pilots. HG's use 'Eggli' Alternative launches: -'Mast 4' preferred by HG, as easily reached by car -'Plandadein' -outside vegetation period only!!! (turns on only in the (late) afternoon)
