If you speak mostly English and are looking for volunteer work, there are a surprising number of opportunities that require little knowledge of Dutch.
It takes some knowledge of Dutch to navigate the websites, which are all Dutch, to find such gems as: carpentry work, feeding animals in children’s farms, helping at a festival, working in a garden that produces food destined for a food bank, delivering meals, and doing English guided tours in museums.
Here are some places to look:
Humanitas could have opportunities to teach English. Also, every two weeks they run a training course for volunteers. https://www.humanitas.nl/
Check a museum website for openings. They might need tour guides in different languages.
Vrijwilligerswerk.nl, has openings for jobs such as taking someone from a village to a hospital appointment, and a number of one-time only jobs. https://vrijwilligerswerk.nl/
At Onlinevrijwilligerswerk.nl, one of their listings seeks volunteers to work for Oerol, (a festival). http://onlinevrijwilligerswerk.nl/category/organisaties-groningen/
Here are some local suggestions for Groningen:
Vrouwencentrum Jasmijn sometimes have opportunities to teach English. http://www.jasmijn.info
Hortus Haren often need people to help with weeding, pruning, painting, electrical and carpentry work. Currently they are looking for a volunteer to translate their website into German. Since it is not in English either, perhaps a volunteer could offer to do it. http://www.hortusharen.nl
