Sightseeing

The "Kalmthoutse Heide" is a big natural park in Kalmthout. It is open to the public and has more than 15 different routes that can run for tens of kilometers.

The first synagogue outside of a city in Belgium was built in 1928 on Leopoldstraat in the village of Heide. This pre-dates the Catholic church St. Jozef's and can be seen on the local walking tour. The Jewish community played an important part in local history, with the first Belgian yeshiva also being built in Heide. Many architecturally innovative villas from the community still stand and can be seen during walking tours guided by local historians.
