Fort Nassau, Kievitte Polder and Het Zwin Loop

Starting from the outskirts of Terneuzen, near the historic Fort Nassau, this 14 km (about 8.7 miles) loop offers a flat, easy-going route with virtually no elevation gain, making it accessible for hikers of all abilities. The trailhead is conveniently located near the Fort Nassau parking area, which is easily reached by car via the N61, or by public transport with buses from Terneuzen’s main station stopping nearby.

Historical Highlights and Fort Nassau

The hike begins at Fort Nassau, a star-shaped fortress dating back to the Eighty Years’ War. Built in the early 17th century, the fort played a crucial role in the defense of the Scheldt estuary and the surrounding Zeeland region. Remnants of the fort’s earthworks and bastions are still visible, and interpretive signs provide insight into its military past. The area is dotted with old cannons and reconstructed ramparts, making it a fascinating spot for history enthusiasts.

Kievitte Polder: Wetlands and Birdlife

Heading north, the route enters the Kievitte Polder, a reclaimed landscape characterized by wide-open fields, drainage ditches, and grazing livestock. This section, stretching from about 2 km to 7 km (1.2 to 4.3 miles), is renowned for its birdlife. In spring and autumn, the wetlands attract migratory species such as avocets, spoonbills, and various ducks. The flat terrain and open vistas make it easy to spot wildlife, so binoculars are recommended. The polder’s network of dikes and canals is a testament to Dutch water management, and information panels along the way explain the engineering feats that keep the land dry.

Het Zwin Nature Reserve: Coastal Beauty

At around the 8 km (5 mile) mark, the trail enters Het Zwin, a cross-border nature reserve straddling the Dutch-Belgian border. This tidal estuary is a mosaic of salt marshes, mudflats, and dunes, supporting a rich diversity of flora and fauna. Expect to see wildflowers in summer and large flocks of waders and geese in winter. The reserve is also home to rare plants adapted to saline conditions, such as sea lavender and glasswort. Wooden boardwalks and observation hides allow for close-up views without disturbing the habitat.

Navigation and Trail Conditions

The entire loop is well-marked, but carrying a digital map on HiiKER is recommended for real-time navigation and to check for any seasonal detours. The path consists mostly of gravel and dirt tracks, with some paved sections near villages and farmsteads. Waterproof footwear is advisable after heavy rain, as some stretches through the polder can become muddy.

Facilities and Access

There are several rest areas and picnic spots along the route, particularly near the entrance to Het Zwin and at small hamlets like Retranchement. Public toilets and cafes can be found in Terneuzen and at the visitor center near Het Zwin. Cyclists and dog walkers also frequent parts of the trail, so be mindful of shared sections.

Getting There

For those arriving by car, parking is available at Fort Nassau, just off the N61. If using public transport, buses from Terneuzen’s main station stop at Fort Nassau, making it a straightforward journey from larger cities like Middelburg or Ghent. The area is well-served by regional bus lines, and schedules can be checked online for the latest updates.

This loop offers a blend of history, nature, and Dutch engineering, with easy terrain and plenty of opportunities for wildlife observation and cultural discovery.
