Early Midsummer Night Hike, Swimming and Picnic

It is a bit too early for a midsummer night party, but on the weekend the weather forecast predicts thunderstorms. On Friday evening, we will celebrate midsummer night with a hike through Königswald and a picnic, including swimming, at Sacrower Lake. We’ll meet at the Wannsee ferry terminal (near Wannsee S-Bahn station) at 17:55 and take the ferry to Alt-Kladow at 6 pm. The ferry ride is covered by a standard BVG ticket (Zone B). (The next ferry leaves an hour later, so please allow about 5 minutes to walk from the S-Bahn station to the terminal.)
From Alt-Kladow, we’ll follow freely this Komoot route: https://www.komoot.com/de-de/tour/1585149981 . I aim at a hike duration of 2 1/2 hours. After 12 km, we want to arrive at Sacrower Lake. Bring swimwear, food and drinks and, if you like, champagne to celebrate the best time of the year. At around 22:30 we leave the lake and head for the bus station in Alt-Kladow.

For communication during the hike, I will send a Signal group link to all participants via private message a couple of 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 allows us to share our locations during the hike without involuntarily forwarding this information to the intelligence services of authoritarian or non-authoritarian states, but unfortunately the location sharing function does not include tracking, i.e. no continuous updates.
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.
