The Regte Heide – Goirle is located a few kilometers south of Tilburg, close to the Belgian border, and is approximately 250 hectares in size. The Regte Heide is a unique nature reserve surrounded by the Oude Leij and Poppelsche Leij stream valleys with heathland and forests. The entire area is home to numerous species of plants, butterflies, and birds. What makes the place a one-of-a-kind preserve are the historic Celtic burial mounds from the Bronze Age that can be found here: indicating that Celtic settlements existed here from 2000 to 700 BC.
