In many countries this starts in spring; even the desert gets transformed into a sea of flowers. The flower season can also depend on the geographic location.
The wild daffodils are in bloom between the end of March and beginning of May depending on weather conditions the weeks before. Mostly it is best mid- to end of April. In 2017 the wild daffodils were already in full bloom April 9th. It was warm and sunny before.
The different daffodils trails around Monschau/Kalterherberge are very popular. At weekends, many people walk this trails from midday on. If you start early you can beat most of the crowds. It's worth to combine the hike we did with a detour of around 1 1/2 km to get to the Bieley Rocks directly across the border on the Belgium side. This part has not marked the reason for very view people. It’s military restricted zone and sometimes closed due to sharpshooting. Days are listed on a huge sign.
