Situated about 50km East of Amsterdam, Six Flags Holland is accessible by car or bus and train, and can make a really fun day out for the kids. Prices are usually around 23.00€ for adults, and 18.50€ for kids, although these prices can vary as they often have special discounts so check out their website for the latest details. Virtually all the rides are free once you're inside the park, and there's plenty to do. Excellent roller-coasters include the enormous Goliath, and thrashing Superman. Go-carting and various arcade type activities are not included in the entrance price and must be paid for separately.
The food is mostly mass catered Burgers & Fries, ices and the like, but you can easily take along something tasty as there are plenty of places to picnic.
