It's a great route. Thanks for posting (Grazie, complimenti).
This is a really interesting part of Europe to visit as it's a meeting point between three different languages and cultures.
If anyone is thinking of doing this route, there are some options/variations that are worth knowing about:
- there's a spectacular cyclewaye (the FVG1) which follows the old railway line to Resiutta south from Tarvisio. This won an award for being one of Europe's best cycleways. It's well worth doing as a side-trip (or you can continue following the Ciclovia Alpe Adria Radweg to Grado on the Adriatic coast);
- the upper section of the Drauradweg is also worth exploring.This starts at Toblach (Dobbiaco) in Italy where it links to other international routes - so for example you could come into Italy by the Brenner pass and then follow the PusterBike cycle route through the PusterTal to Toblach and then cross back into Austria. Note though that Drauradweg has some long sections of unsurfaced cycleway - definitely do-able on a decent touring bike;
- in Carinthia there seems to be a network of good well-signposted routes around the lakes between Villach and Klagenfurt which looked like it would have been worth a detour to explore;
- there are a couple of projects to promote cross-border cycle routes between Slovenija and Italy. For example there's the
AdriaBike route which runs from Kranjska Gora to Ravenna and the
Bike Alpe Adria (unfortunately there are a number of projects with very similar names) which promotes a number of routes mainly to the south of The Trglavski Narodni national park including a circular route linking Tolmin, with Cividale del Friuli and Gorizia.
(Note to cyclingovereurope - I couldn't get the links from the index/sommario page to work on my iPod - presumably because it uses Flash animations. did I miss something? It might be worth putting in some normal links as a back up - otherwise there doesn't seem to be any way to navigate through the articles).
). In the meantime this is the link to first stage (http://cyclingovereurope.blogspot.it/p/season-2-stage-1.html) I will try to improve the smartphone version soon (Hoping to find time!!!
