My wife and I visited Kletterwald on a Saturday. The place is reachable from the Meinendorfer Weg U…read morebahn station. The entrace to Kletterwald is just opposite to the U bahn station. One needs to walk a little inside to find it. We had bought tickets online, so at the shop, I just had to buy a pair of gloves (€3). A mask must be worn at the shop. They also provide a locker free of charge but with a €5 refundable deposit. There are portable toilets near the back of the park next to the car parking lot. The staff were very friendly and spoke English. They helped us wear the harness and gave us instructions. They also gave us the helmets. We didn't need to wear masks while doing the courses. They kindly showed us the way to course 1. We did courses 1, 2 and 4. Courses 3 and 5 were available only in the presence of an instructor. Course 1 and 2 have a zip line at the end. Course 4 does not have it; there's a simple wooden staircase at the end. Overall it was easy and doable. I struggled a bit on one of the bridges in course 4. It needed a lot of upper body strength. We finished course 4 and were too tired to go for course 6. We returned back to the shop area and returned our harnesses and helmets. We emptied our locker and bought some ice cream in the hot summer weather at the shop. We spent about 2 hours at the place. Overall it was a fun experience and we'd love to visit Kletterwald again!
