It's handy to know if you are coming to Mechelen by coach that there is one place to (dis)embark in the city centre. It is on Veemarkt. You can drive to it along Keizerstraat, let your passengers disembark on Veemarkt and drive out of the city again via Biest and Frederik de Merodestraat. In principle, the coach can wait on Veemarkt for fifteen minutes.
There are free-of-charge parking places on the Douaneplein and on the Vesten adjacent to Het Anker brewery.
If you are coming from Frederik de Merodestraat, turn left. Then follow the ring-road round to the Rode-Kruisplein, where you can make a U-turn to access the parking places on the other lane.
If you want to park on the Douaneplein, continue along the ring-road to the junction with Leuvensesteenweg. Turn right there before taking the first left to the Tangent. At the end of the Tangent, turn right to the N15, direction Douaneplein.
