Visitor info

The Dwingeloo Radio Telescope is located on one of the busiest bicycle routes on the Dwingelderveld and with its 25-meter diameter, the telescope is almost impossible to miss. For passersby there are information boards about radio astronomy next to the telescope. The telescope is open to the public at some Sundays and Wednesdays during holydays, and special national and regional activities if the covid-19 measures allow. It is not yet possible to request group visits. Online demonstrations (in Dutch) are announced here or can be viewed here again.

– Route

Access to the radio telescope is via the former official residence – bungalow -, the Muller House, on the Oude Hoogeveensedijk 6 in Dwingeloo and not via the information boards along the sandy road. See contact en route (Dutch).

– Special openings

CAMRAS cannot yet indicate whether the radio telescope will be opened or closed this year (2022) for the following public activities. That depends on the then current covid-19 measures. At a closed radio telescope, our volunteers will try to provide an online demonstration.

Online demonstrations (in Dutch) are announced here or can be viewed here again.

In case of special openings, other entrance fees or free access may apply.

In case of equipment malfunctions, we give a tour without demonstration.
In case of exceptional weather conditions such as thunderstorms and very strong winds and strong gusts of wind, the tours are canceled.

High school students can do their own research or experiment with the radio telescope, for example for a practical assignment. For more information and requesting this, read the education page.

– Guided group tours on request

Guided tours for groups are possible on request. Real observations are made during a tour. For example, it is possible to listen live to a pulsar or to measure the velocity of hydrogen clouds.

In group tours, depending on the interest of the group, the emphasis can be placed on the technique of the telescope, on astronomy or on applications for radio amateurs. The telescope is also interesting from the point of view of heritage. For more information and to request a tour, read the page about guided tours.

  • For guided tours on request, the radio telescope is still closed due to the covid-19 measures in force. We cannot yet indicate whether the radio telescope will open for guided tours this year (2022).
  • The entrance fee depends on the number of group members together but is always at least € 50.00.
  • We do not organize and guided tours after 18:00 hours (6 PM) and on national and generally recognized holidays.
