A great day out on the river Isar with DER Touristik & Incentive München
Raft trips on the Isar take place from May to mid-September. DER Touristik & Incentive München offer perfectly organized raft trips in the heart of Bavaria. A trip on an ethnic log raft is an adventure you will never forget. Originally, log rafting was a way to transport bulky goods, but now it is a fun activity popular among young and old people. The rafts are built exactly in the same way as a hundred years ago. Today, however, they are taken apart in Munich and transported back to Wolfratshausen, so that our log raft service and the fun can start all over again on the next day. Choose to take part in one of these raft trips, and you’re in for a great day out on an ethnic log raft, with draft beer, a traditional Bavarian breakfast, Bavarian music and lots of fun! www.isarflossfahrten.biz
