Clervaux is a town in the northernmost district of Luxembourg. This old town of approximately 1,800 inhabitants lies within the Ardennes, a forest-covered area spreading over Belgium, Luxembourg and even some parts of France. Clervaux is located in a narrow valley at the banks of the River Clerve. The surrounding hills are covered with thick forests.

The region enjoys a moderate climate. Summer is the best time to visit; July is the hottest month with an average temperature of 17.5°C. During winter, the temperature tends to hover around the freezing point.

Though primarily a market town, the city had a rich history owing to its tumultuous surroundings. It was the residence of the powerful knights and counts of the region.
