Just a 3.5 hour drive from Calais, the Duinrell Resort is famous for its on-site theme park and Tiki Pool waterpark, making it one of the best holiday parks in the Netherlands for family fun with the kids. It has over 20 thrilling waterslides, as well as indoor and outdoor swimming pools. Finn and Lola adored it – make sure you check out my Duinrell Review to find out more. You get unlimited access to the theme park with rides to suit kids of all ages, and there’s an indoor games room. For days out, there are gorgeous beaches nearby, you can reach Amsterdam in 45 minutes and enjoy a day at Efteling too (if one theme park isn’t enough!). The nearest airports to Duinrell are Rotterdam Airport and Amsterdam Airport – no more than 30 minutes away.
