Why not rent a pedalo or a rowing boat and take a cruise on lake Zurich to enjoy the sun - and the water, maybe. You can’t miss the rentals: two of them are situated on platforms on the lakeshore between Bellevue and Zürichhorn, one on the river side of the Quaibrücke at Bellevue and one on the Enge side of the lake. Prices: pedalos 20 - 35Sfr/h, motorboats (6 - 8 HP) 58 - 70Sfr/h. No reservations, just show up and wait for one.
