De Gronselenput is a small, car-free nature campsite situated on a narrow peninsula-like strip of land almost entirely encircled by the river Geul, at the foot of the Keutenberg in the rolling hills of Zuid-Limburg, near the village of Wijlre.

The roughly 2-hectare site has a history of nearly a century and is run by volunteers affiliated with Nivon.

Pitches are spacious and set on open grassland bordered by trees and shrubs, with the Geul visible but separated from the camping area by vegetation and a fence — a reassuring arrangement for families with young children.

Wildlife along the river includes beavers and the occasional kingfisher. The campsite is well suited to walkers and cyclists, with numerous routes through the surrounding South Limburg landscape of half-timbered farmhouses, roadside chapels, and gentle hills.

Facilities include a small paddling pool, playground equipment, and a covered cooking area for wet weather. Two fully equipped four-person safari tents are available as rental accommodation.
