The Erlenbrunnen (also called "Erlebuhr", "Saurebuhr" or "Eedel" (after a nearby quarry)) is located between Bell and Mendig and was built in 1809. It is on the route of the "Traumpfad - Four Mountains Tour".
On the ridge called "Castellberg" above Wallendorf, near where the Our flows into the Sauer, the Celtic Treveri built a fortified settlement similar to a town in the 2nd century BC. Today, almost nothing of it is visible above ground.
The most popular "Drees" in the town of Daun is the "Hotzendrees", located at the foot of the Burgberg (castle hill) and a stop on the "Drees" hiking trail. The tasty sparkling water "bounces" out of its source.
