How to get to Cabauw by car

View the map for the main route to get to Cabauw. Note that you have to leave the 'N210' road at the traffic lights at the western border of the village "Lopik". After leaving the 'N210' turn immediately left again on to the smaller road parallel to the 'N210' but on the other side of the small waterway.

If you want to take your time, the scenic road from Haastrecht to Schoonhoven or the small winding road from Linschoten to Oudewater are worth the detour. Oudewater is nice scenic town with some canals and old buildings.


How to get to Cabauw by public transport

From Central Railway Station in Utrecht take bus 195 in direction of Rotterdam. On weekdays the bus leaves almost every half-hour at approx. hh:06 and hh:36 from the station. It takes about 35 minutes to get to Lopik. Leave the bus at the last bus stop in Lopik (just after the last traffic lights), ask the driver if you are not sure about the correct bus stop. From the bus stop it is a 15 min. walk to the tower itself. You need a "strippenkaart" which you can buy amongst others from the bus driver, or at the service shop at the bus station. The bus ride to Lopik will cost 7 "strippen". For the exact present time schedule of the bus see the website of the bus company (click here).
