Glistening in the sunshine in the unspoilt countryside of the Prüm Valley close to Bitburg, is the Biersdorf reservoir. The beautiful wooded hiking paths in this area attract keen walkers all year round. The hotels overlooking the lake provide an ideal holiday retreat, with excellent spa and sports facilities and fine dining in cosy restaurants. In the summer months the area around the lake becomes a hive of activity, its vast area a magnet for watersports fans and anglers. Just a short walk away are the delightfully romantic Hamm Castle and the medieval hermitage at Wiersdorf.
