Tell me more about the Col de la Faucille. It won't be snowing in May will it? Or is it not that high? I would love to go through the Swiss Alps.
Col de la Faucille is not in the Swiss alps. It is in the Jurra Range which is a belt of mountains north of Lake Geneva in southern/central France. there are some spectacular roads in the Jurra, but the weather can get seriously gnarly, very quickly, so care is required, particularly on unprotected (no guardrail) roads. La Col is the pass up into the range from Fernay Voltaire - just west of Geneva on RN5.
It is very, very steep in places, with numerous switchbacks (though nothing as wonderfully engineered as Stelvio, Brenner or Susten). It climbs through a forest, with some superb views of Lac Leman and Mont Blanc in the distance and has a ski resort at the peak, with some great restaurants and stunning views, in all directions. There could well be snow on the ground in May, at the top.
It is a challenging road (tougher descending), but a lot of fun, if not too busy.
My brother Dave H has CYCLED up the damn thing (bet he couldn't do it now, eh Dave?)
Hope this helps.
