• Cash only on board, since each ferryman is self-employed and collects the fare; there's an ATM at the harbor
• No booking needed for the public rides: boats leave every few minutes once full, and the day's routes are posted by the basin
• The 2-hour ride suits younger kids, with a 30-minute stop in Lehde; the 3-hour classic gives a full hour there

Punts are flat-bottomed boats up to 9 meters long, with benches for about 20 people. The ferryman pushes off the riverbed with a four-meter ash pole, no motor, telling stories as the boat passes potato and cucumber fields.

Routes lead to Lehde, a village whose main street is a canal, with a stop for the open-air museum or lunch. Ducks follow the boats; watch for storks and dragonflies.
