Forellenvijver aan de Grens is a trout-fishing venue located in Baarle-Nassau, Noord-Brabant, right on the Dutch-Belgian border — a setting that gives the site its name.

The facility comprises three trout ponds nestled against a woodland edge in the Brabantse countryside, near the Merkske river area.

Visitors fish in flexible time blocks, with the option to start a four-hour session at a time of their choosing within the venue's operating hours. The ponds can also be hired exclusively for groups by arrangement.
