This is a great opportunity to get a taste of the mountains, just a few kilometers east of Salzburg. Gaisberg Mountain rises some 2,600 feet, with several hiking paths leading to the summit. For runners, there’s a 5.2 km circuit called the Gaisberg Rundwanderweg (“balcony of Salzburg”), that starts at the Hotel Zistelalm. It is a combination path/boardwalk type trail, which has great views of Salzburg, Wallersee Lake, and the surrounding mountains. From the hotel, just follow the road/path called Oberwinkl. This is a reasonably challenging run, with 730 foot gain, with one significant climb of 600 feet over the first 1.4 miles, with an average grade of 8%. NOTE: Might not be runnable in winter.
If you’d like to summit Gaisberg, from the hotel it is 2.3 km one-way, with an elevation gain of 900 feet and VERY steep grades! A road does lead to the summit, so you could always have a partner take you to the top and you can run down!
