15km-circular hike through Kreuzberg/Tempelhof, including museum

Sunday will be a partially sunny day. We meet at 10 am at the U-Bahn station Mendelssohn-Bartholdy-Park at the corner Reichpietschufer/Köthener Straße and walk the following route - https://www.komoot.com/tour/2660606976 - passing by some monuments and the like.
After three quarters of the hike, we visit FHXB Friedrichshain-Kreuzberg Museum for approximately an hour (free entrance) and/or have a coffee.

If you need to contact other participants during the hike (for example, to find out where to meet us if you are running late), please use the Signal group link that I will send to all participants via private message three hours before the hike. This timing is intended to prevent non-participants from misusing the link for unwanted advertising, which has happened in the past. Signal also allows us to share our locations during the hike without involuntarily forwarding this information to the intelligence services of authoritarian or non-authoritarian states. For all other purposes, especially socialising and posting photos, please use the Telegram subgroup 'Event Chat & Photos': https://t.me/addlist/KAOk2PA4BDE0ZTY8 .

The hike will take place if at least 6 people sign up. As long as there are more than 6 people, you can sign up and cancel as many times as you like. If there are 6 or less people, please avoid cancelling, as this might make the other participants feel insecure about whether the hike will take place (or whether there is something wrong with the hike and they should cancel as well --> Matthew effect - Wikipedia). If there are less than 6 participants, the hike will also take place unless the majority of the participants are in favor of canceling the hike.
