The Calmeyn route (4 km) is a small loop through the dune forest on the edge of the nature reserve De Westhoek. The two-way route connects to the Panne route and the West Coast route, and is a worthy alternative in times of high tide.
The Calmeynbos was named after Maurice Calmeyn, a large landowner, who had this dune forest planted in 1902. With this experiment, Calmeyn, who was an agricultural engineer, wanted to prove that it was perfectly possible to grow trees close to the sea and thus prevent sand drifts in the dunes. Despite opposition from renowned foresters, who doubted the success of the experiment, Calmeyn planted no less than 27 tree species on an area of 55 ha. A quarter of a century later, his efforts resulted in a mixed forest consisting of an assortment of some 30 tree species (Elm, Sycamore Maple, Poplar, Ash, Hazel).
