About 30 miles of only tight turns rising through the forest ro the Puerto del Sarrablo. Really good road if you like successive tight twisties.
Driving up to the Col from France was OK but not inspiring-- be aware of free range cows and their end products!! The Spanish side was superb--road surface great, traffic almost absent, brilliant ride down to the foothills and valleys. GPS (Zumo 550) got a bit confused, but you can't really go wrong----great ride.
A good route over the Pyranees, leave Pamplona, then use the N135 toward the hills. The road has a few places where it is easy to get lost, keep using the signs to France. The route goes through quite an easy pass, but the road is interesting and fairly quiet, even in summer, although there are a few of the obligatory mad cyclists. There are a few shops selling food, but these open infrequently, there are no petrol stations! Join the D933 toward St Jean Pied de Port, you seem to be quite suddenly in town. Stop at one of the cafes, no greasy meals, but very good coffee.
Not a very well-known pass but its a beauty. Great tarmac and good visibilty make this pass to one where you can really open the trottle if you get the chance. In the beginning it is pretty straight forward but pretty fast after the Italian border the sharp turns and switchbacks build up rapidly. When descending into Italy, you will arrive at a T-junction. If you want to be thrilled beyond believe go left (i.e. the direction which is forbidden for trucks and campers). You will find a steep descend into various blind corners in and out of tunnels on a narrow road. Not for the faint-hearted or mountain-newbies, but a challenge for the advanced riders.
When arriving in Chiavenna, follow the SS37 back into Switzerland to the Maloja-pass and Julier-pass: both open and insanely fast.
Comments: Among my riding experiences in Switzerland, I would rank this route as Number ONE. If you are lucky to have a clear day to ride this route, expect views for miles and miles. The road winds up and up through a long alpine valley with sky-scraping granite peaks, and then back and forth up the valley wall until all the trees are gone. There is a nice spot at the summit to stop for a coffee and the loo. We spotted a cow behind the restaurant gently chewing its cud so as not to disturb the enormous bell hanging around its neck, briefly enjoying a moment of peace. On the way back down towards the east the road is literally carved into a cliff, providing a bit of the \'whoops\' in your belly as you peer over the guardrail. There is an unbelievable waterfall across the valley that drops several hundred meters into the green abyss, rare these days as most are tapped for electric power generation. The trip ends down near the Vierwaldstaettersee in Altdorf, where there is a monument to William Tell. The ride along the lake to Schwyz is amazing follow-on, but I shall describe it in another entry. Although this website does not support photos of the routes, please go to my travel-log, www.travel-switzerland.net and look for the link \'Klausenpass\' to see more info and photos. Be very careful of your speed, particularly on weekends. We passed many a bicyclist grinding up the 8% grade, plus boneheads like me who are constantly pulling over for photos. This is a road where you could tear around the switchbacks, only to find a motorcop with a radar gun sitting there waiting just for you. I know, I followed him for about 15 km. But then I stopped at nearly every place he did because of the spectacular views. (He used them to watch for likely candidates.)
