The Oolderplas is a lake located near the village of Ool, southwest of Roermond in the Netherlands. It sits in the Limburg region and is accessible by car, with a short walk from the parking area to the water's edge. To reach it, drive southwest from Roermond toward Herten, then head west on Maasstraat to Ool. From there, turn left onto Groeneweg, then right onto Broekstraat and continue west to the end, crossing the dam to reach the parking lot. Paid parking is available on site.

The water character ranges from flat to choppy, depending on wind conditions. Water clarity is generally cloudy. The shoreline is predominantly grassy, offering ample space to prepare gear before launching, though a few trees are present along the water's edge and should be noted as a minor hazard. The lake is tide-independent, making it accessible at any time without tidal planning.

Wind at the Oolderplas is primarily frontal in nature, driven by westerly weather systems. The prevailing wind directions are southwest through northwest, with WNW considered the best direction. The most favorable months for wind-dependent activities are March, April, May, September, October, and November, with spring and autumn generally offering the most consistent conditions. Summer can also be suitable on warm days, though winds may be less reliable.

Water temperatures follow a typical northern European seasonal pattern. During warmer summer days, a shorty or light wetsuit may suffice, though a full wetsuit is recommended on cooler summer days. Outside of summer, a wetsuit is always advisable, and during winter months a thick wetsuit is necessary.

On-site facilities include a kite school, rental equipment, food service, and parking, making it a reasonably well-equipped destination. The lake accommodates paddlers and water sports enthusiasts across a range of skill levels, from beginners to experienced riders.
