Situated half an hour southwest of Groningen, Posta 7 is an all-embracing activity centre suitable for groups of all themes and sizes, be it family or work events. With over a dozen programmes from escape games to bowling to outdoor tours, it's all up to your definition of fun. For the essential bites and drinks, the historic De Postwagen restaurant provides a variety of options including high tea, buffets and barbecue. It's advisable to enquire beforehand about opening hours and availability, including those of the restaurant, as they may be subject to large group bookings.

The iconic blue-domed mosque is one of the country's most recognisable attractions, a place of worship as much as a national landmark and even somewhat of a museum: a few archaeological finds and personal items of King Abdullah, who inaugurated the mosque, are also displayed here. Unlike at most other mosques, non-Muslim visitors are welcome inside, provided they follow the rules of attendance.

White Pines Park and Lake, adjacent to the town of Arnold on scenic Ebbetts Pass, provide families with a multitude of outdoor recreational opportunities. The lake itself is quite the hidden gem: plan a picnic by the lakeside for a lazy Sunday. For those seeking an active weekend, take to White Pines Community Park for BBQs, paths, a playground, a group area, a beach, and a softball field.
