Boschmolenplas is a well-known freshwater dive lake near the village of Heel in the municipality of Maasgouw, Limburg. Fed entirely by naturally filtered groundwater, the lake stretches more than 1 km in diameter and reaches a maximum depth of 32 meters.

Water clarity is exceptional, with visibility frequently exceeding 12 meters, supporting a rich variety of underwater flora and fauna alongside a collection of artificial objects and distinctive clay walls.

The site draws scuba divers, free-divers, and biologists from the Netherlands, Belgium, and Germany year-round. Four entry points are equipped with walkways, stairs, and ramps, including facilities for visitors with disabilities.

Access is managed through the on-site dive centre, and a valid diving licence is required. Solo diving, buddy lines, barbecuing, and pets are not permitted on site.
