Organization details

Accommodation in Obergurgl is booked by the organizers, guests stay at the conference venue.

Costs. Accommodation including breakfast and dinner costs EUR 72.50 in a double room and EUR 104.50 in a single room (per night); lunch is approx. EUR 18. There will be no conference fee. The workshop is supported by KAUST, by the Austrian Science Fund, and Deutsche Forschungsgemeinschaft DFG.


We recommend to fly to Innsbruck on Monday, September 20, and fly back on the 25th. You probably cannot fly direct, but there are good connections to Frankfurt and Vienna. You could also fly to Munich, which has a train connection to Innsbruck (and onwards to Obergurgl) directly from the airport.

Fastest travel from Innsbruck Airport to Obergurgl (1.5 hours) is via an airport shuttle. It costs about EUR 200 and makes sense if you share. We are happy to help coordinating shuttles. Cheapest travel to Obergurgl from Innsbruck is to take a train to ``Ötztal Bahnhof'' and a bus to Obergurgl (in total 2.5h).

Touristic Information
Wiese Ötztal  

Ötztal draws many tourists, and Obergurgl is part of this. See e.g. the web page of Ötztal tourist information (summer) and Obergurgl tourist information (summer). Good places for walking and mountaineering are Obergurgl itself and nearby Vent. At the end of september the high country season is drawing to an end, but stable weather is common. Obergurgl is also an area of long-time glacier and climate observation. Geomorphological features include active rock glaciers besides many ordinary ones.
