Glyderau is a pretty fine launch site for exploring a couple of miles of the South facing slopes of the Glyderau.

Don'ts: 
  • Land in the fields North of Llyn Gwynant campsite.
  • Land south of the main road in the Ogwen Valley between Tryfan and Gallt yr Ogof.
  • Land North of the road between Plas y Brenin and Capel Curig.
Challenges: 
  • Watch out for sea breezes mainly from the West.
  • Make sure you have plenty of height if going over the back.
  • Watch out for power lines in the valley towards Llyn Gwynant.
  • Watch out for valley skimming jets on weekdays if you go. over the back, because chances are they won’t see you!
  • Getting the heather out of your lines if you choose the top take off.
Safety: 

A big hill with lots of rocks…most hazards are obvious. It is worth noting that the ridge to the E of take off is flat topped generally grassy and broad. To the W of take off the top of the mountain is almost completely rock covered with irregular boulders. The extreme W of the ridge top is narrow and drops precipitously into Cwm Idwal.  When there is a dynamic soarable breeze low down (and especially in winter) it can be very windy over the top of the ridge.  On thermic days that start off light, Sea breeze coming up the Gwynant valley can make it windier down in the valley than over the ridge. Often Siabod gives some shelter to the valley in front of the  Glyder (where it is locally less windy than expected). Be aware that winds may be stronger outside of this zone if you go down wind.
