We just used the campsite for a short stay so didn't explore Luxembourg but there are enough activities on site to keep the family entertained. Swimming pool, playground, tennis courts are all excellent. The couriers were very welcoming and knowledgeable.
Stayed for two nights before moving on to Germany. Lovely location, good walks into town with great views. Enjoyed a walk to the castle, then a good value and tasty meal in town. Kids aged 8 & 10 enjoyed the play park and the pool. We went without a car but found site accessible if you don't mind using buses and trains.
only stopped for an overnight stay on route to switzerland - accommodation was very clean,courier was very good. Pool was nice and food in restaurant was good and not too expensive. Nice walk into town ( a bit of a hill on way back) but not too much in the town.
