Hahntennjoch is a high mountain pass at an elevation of 1.894 m (6,214ft) above the sea level, located in the Austrian Alps, in the Bundesland of Tyrol.
The asphalted road over the pass, called L266, connects the Inn valley starting in the village Imst with the Lech River valley. The road leads from Imst to Elmen, a distance of 29 km. It is popular with motorcyclists and cyclists.
This road is very exciting and sometimes very exposed and unsecured driveway in innumerable twists and turns. The road is winding and steep, with grades up to 18.9 percent and is closed to traffic over 14 metric tons. The drive is definitely worth it. You can catch views of glacier-carved valleys, daunting peak summits and densely wooded areas.
This infamous road is tightly hairpinned and bumped, an exquisite winding mountain drive with sharp and blind curves and hairpin switchbacks leading the traveler over the mountains. On the Inn valley side the pass road runs in very close turns runs along the cliff. The road is very narrow and in the summer season there are enough crazy motorbike riders that try to pass by in the most dangerous situations. The accident frequency is accordingly high.
This road is usually closed from November to April, but it can be closed anytime when the access is not cleared of snow. The pass is prone to avalanches, falling rocks, and mudslides. In 2004, an automatic system was installed that closes the road in case of blockage.
Avalanches and heavy snowfalls can sometimes block some sections of the road and can be extremely dangerous due to frequent patches of ice. The pass road is extremely endangered by so called Muren. Muren are stone and mudslides, which go off in the mountains with strong rain and thunderstorms. Large warning signs refer to these dangers and on the left and right side of the road, gravel waste piled up talks about past slides and give an idea of which forces of nature is able. There are 2 routes to reach the summit. Starting from Imst, the ascent is 14 km long. Over this distance, the elevation gain is 1.058 meters. The average percentage is 7.6 %. And starting from Elmen, the ascent is 15 km long. Over this distance, the elevation gain is 908 meters. The average percentage is 6.1 %.
