It is 8:20 pm in June and we are about to enter the twilight zone. Join me on this trip around the Zuger lake near Zug, Switzerland, from daylight to dusk. We are starting in Oberwil bei Zug, taking a clockwise route with the lake always on our right. On the first section we are moving South and towards the Rigi mountain, easily visible with its characteristic slope and the tower on top. We pass the town of Walchwil and enter Arth where we turn West and towards the Rigi which is now looming large in front of us. Another right and off we are towards Immensee and later Cham and Zug. Bonus points if you spot the tractor with broken axle in the field to our right. We eventually leave the busy road and enter a small limited access road enjoying rolling hills in the country side. Eventually we enter Cham, and follow the bike path to Zug where our ride ends at the Katastrophenbucht, with the lake fountain in sight.
