If you are looking for a unique and mysterious hiking destination, you can visit the Pillar Alignment in the Gâvre forest. This site is made up of approximately 120 quartz blocks arranged in a single line that extends over a kilometer. It is one of the longest megalithic alignments in Europe, dating from the Neolithic or Bronze Age. You can access the site from the Pilier roundabout and the Breuil de la Herse forest path. Prepare to walk for about an hour in the woods and admire the old stones that have stood there for thousands of years.
