Many canal tours in Den Bosch are partially subterranean adventures. Of several options, the most popular depart three times hourly from Molenstraat for 50-minute loops. Commentary is generally in Dutch but with a brochure in English. The manoeuvring through narrow spaces and low gaps is memorable in any language.

The ticket office is around the corner in the Bolwerk St Jan cafe, down steps beside the river in a low-slung cafe building incorporating an excavated section of old brick fortification. Online advance ticket reservations, available up to one hour before departure, are worth considering at weekends and peak holiday periods.
