A walk in Halle Woods is a must all year round, but between mid-April and early May, it's even more special. At this time, the bluebells are in bloom. These spring flowers create a magnificent purple carpet. It depends on the weather, of course, but fortunately lasts for two or three weeks. This gives you plenty of time to admire the carpet of flowers.

A picture of the pastor's path between Oudenaken and Sint-Laureins-Berchem. In earlier times there was only one pastor for both parishes. He resided in the only rectory that was located in Oudenaken. The pastor's path was the fastest connection on foot between the two parishes.
