We spent a fortnight at de Molenhof in the middle of August 2013 with our 6 year old son. A quality 5-star site set in the beautiful area of Twente on the east side of Holland, close to the German border. It's a fairly large campsite (approx. 450 pitches) geared towards family camping with children under 12.
As is quite common on Dutch sites, the campsite is spread across several smaller fields, each with a little playground in the centre. That gives it the impression of being a much smaller site than it is. This site does allow cars into most of the fields, but there are a couple of fields where vehicles aren't permitted at all (this is quite typical of a lot of Dutch sites). Our field did allow cars but there wasn't an issue with heavy or fast traffic at all.
There's a very relaxed feel to the campsite, and the facilities are amazing and meticulously clean. Each pitch is spacious (min 100m2) and all have their own water supply, EHU (10 amp but never tripped), drainage and cable TV. As it's a site geared towards kids, there are an abundance of things for them (at no extra cost). Apart from different playgrounds in each of the fields, there's a daily program of activities and include shows/activities in the on-site theatre, an undercover play barn (great if the weather's duff), a large outdoor playground, air trampoline, sand/water/digger play area as well as an outside paddling pool/water slides and a covered indoor pool and water chute.
Bike hire is available (take advantage of the loads of bike trails in the area). There's a well stocked, reasonably priced shop, which also bakes their own bread/cakes, etc. On site throughout the day (croissants are particularly delicious). Additionally there's a bar/restaurant (we didn't eat there) and a snack bar/pizzeria. A limited menu but the food was alright and average prices. Another plus is free WiFi across the whole site - just ask when you check-in for the WiFi password. We found the overall service not too bad. We found it a bit of a hike to the bins (unless there are others dotted around the site) and they recycle. Even the bins are situated behind a lovely purpose-built wall to hide them away!
There's a laundry area with 4 washers, 3 huge dryers and an iron/ironing board as well as handwashing sinks. I think they're a bit pricey at 5 euros for a wash, but this included 2 soap powder tablets. You might want to take your own and some fabric conditioner if you plan on washing. Dryer is around 2 euros for 30 mins but didn't use them. Iron is 20 cents for 5 mins.
There are more wash/shower blocks than you can shake a stick at, all very clean. Pot washing facilities are undercover within the sanitary blocks. Piping hot water, which is great, but no plugs, so take your own! Showers are free but are on a 7 minute timer. I particularly liked the private sink cubicles, in case you wanted a wash without having a shower. In the larger wash blocks, there are also some special children's showers, bathing, sinks and toilets, all decked out in fun styles. There are also some family bathrooms which include a normal and smaller shower.
There are several wooden bungalows to rent, which looked fantastic, along with some huts that are used mainly for cyclists/bikers passing through and need somewhere to sleep for the night (great idea). It's an extremely safe, child-friendly site. It's a family business and it's incredibly well run. The owners are friendly and are English-speaking. The site even has it's own working windmill, which can be visited on certain days.
Note that the campsite caters mainly to the Dutch and German market, so don't expect there to be many Brits there. In fact, we didn't see any British until we hit Rotterdam on the way back to the UK. Apart from emergency numbers, all the campsite literature and notices are in Dutch, so finding out about the local information was a bit challenging lol! I'd recommend you brush up on some words before arriving, especially those where food/drink are concerned. Even eating in cafes posed a challenge in the area as none of the menus we found were in English.
There's plenty to do in the area of Twente. If you're wanting a beach, there's Hulsbeek recreation park (6km) which has 3 beaches set round a lake. The German town of Bad Bentheim (complete with castle) is only 25km away too. There are pretty market towns of Oldenzaal, Ootmarsum and Tubbergen, as well as cities of Hengelo and Almelo. Usefully, there are a couple of large camping shops within driving distance (Hiddink Caravans in Tubbergen is cheaper). The nearest village is Weerselo, which is within walking distance and has everything you need including butchers, bakers, a large supermarket, off-license and cafe/restaurant. There's a fabulous bar/restaurant directly facing the campsite called Antje & Billies. We had a lovely meal there (try the traditional apple tart - it's to die for).
Highly recommended for a great family campsite with plenty for the kids to do. We're considering returning next year.
