The unpaved road to Klammljoch
Klammljoch (Passo di Gola) is an international high mountain pass at an elevation of 2.288m (7,507ft) above the sea level, located on the border of Austria and Italy. The road to the summit is unpaved and closed to motorized vehicles, but can be traversed by bicycle.
Klammljoch (Passo di Gola) connects the Austrian state of Tyrol with the Italian province of South Tyrol, being located between Sankt Jakob in Defereggen and Sand in Taufers. This climb is a very nice one in fine weather. The surface on this gravel road is often loose, especially along the sides of the road. It's a scenic impressive trip, but requires a good level of fitness. Technically not particularly sophisticated, all the paths and roads are well developed. The round is traversed in a counter-clockwise direction.
Exercise extreme caution when passing on-coming traffic, over-taking and around corners. The gravel road is in a good state and possible to use with a road bike with 23 mm tires. It is up to 12% and thus somewhat hard going with a road bike. The views on the Austrian side are much better. At the top there is a closed toll both. The gravel road down the Austrian side to Erlsbach (1549m) is of similar quality (slightly less good lower down).
