Waterland Neeltje Jans

Travelling the N57, you are on the front lines of the Dutch war with the sea as you traverse the massive developments of the Delta Project, a succession of huge dykes and dams designed to prevent floods. Possibly the most impressive stretch is between Noord Beveland and Schouwen-Duiveland, to the north. The long causeway built atop the massive movable inlets is designed to allow the sea tides in and out of the Oosterschelde. This storm-surge barrier, more than 3km long and spanning three inlets and two artificial islands, took 10 years to build, beginning in 1976.

Around the midway point between Noord Beveland and Schouwen-Duiveland on the N57, the Delta Project's former visitor centre has morphed into a theme park, Deltapark Neeltje Jans, complete with a mermaid mascot. Attractions include a 3D film about the devastating flood of 31 January 1953, a seal pool, a tropical salt-water aquarium, and a water park including a water slide, water playground and hurricane simulator. A boat trip takes you out onto the Oosterschelde for a panoramic view of the barriers and beyond.

The island has a long beach at the southern end, which is hugely popular with windsurfers.

The entire region has coastal sections that are part of the National Park Oosterschelde; there are interesting displays in the unmanned information point across the N57 from Deltapark.

Bus 133 follows the N57 and stops at Deltapark on its run from Middelburg train station (€4.40, 40 minutes, every 30 minutes to two hours) or Zierikzee (€5.30, 40 minutes).
