Landmarks and Points of Interest

- Klaasbrug: Early in the hike, you’ll cross the Klaasbrug, a small but historic bridge spanning one of the many drainage canals. This spot offers views of the surrounding meadows and is a popular place for birdwatching, especially in spring and autumn when migratory birds flock to the wetlands. - Onlandsbrug: Continuing along the loop, the Onlandsbrug provides a vantage point over the marshes. The Onlanden area is a haven for wildlife, including herons, storks, and roe deer. The wetlands are also home to rare plant species, making this section particularly rewarding for nature enthusiasts. - Harrevelderschans: Around the halfway mark, you’ll encounter the Harrevelderschans, a historical earthwork fortification dating back to the Eighty Years’ War. This star-shaped sconce was built in the 17th century as part of the Dutch defense line against Spanish forces. Interpretive signs explain its significance and the broader history of water-based defenses in the region.

Nature and Wildlife

The Onlanden reserve is renowned for its biodiversity. Expect to see expansive reed beds, willow thickets, and open water channels. The area is managed to encourage natural flooding, which supports a rich variety of amphibians and aquatic insects. Birdlife is abundant year-round, with marsh harriers, bitterns, and kingfishers among the highlights. Early mornings and late afternoons are the best times for wildlife spotting.

Trail Conditions and Preparation

The path is mostly gravel and well-maintained, though sections can be muddy after heavy rain. Waterproof footwear is advisable, especially in wetter months. There are benches at intervals for rest, and several observation platforms for photography or quiet contemplation. No significant elevation changes occur along the route, making it accessible for most walkers.

Getting There

From Groningen Centraal Station, take a local bus towards Noorderhoogebrug; the journey takes about 15 minutes. If driving, follow signs to Noorderhoogebrug and park near the village center, where the trailhead is clearly marked. There are no facilities directly on the trail, so bring water and snacks.
