Poster session

For the trip you will need comfortable walking shoes, water and (hopefully) sun protection. Don't forget your camera. We go by tram to the vine growing area at the hills in the north of Vienna.

We will walk some nice paths through the vineyards. There is a bit of uphill walking, 2h walking in total if you go slowly.

The more ambitious walkers can go to the top of Kahlenberg which is also offering nice views over Vienna.

After the walk we will meet in Nussdorf at "Steinschaden" where we have dinner. This is a typical Viennese "Heuriger", a basic "restaurant" where the owners of a winery sell their products. At night the tram line D will bring you back to the city
