The city of Trechtingshausen is located at the foot of the forest "Soonwald" with Sooneck castle close to the nature reserve "Morgenbachtal". At the access to this valley Reichenstein castle, built on the remains of a former Roman fort, dominates the environment.

Worth seeing in this traditional wine city are the remains of the medieval fortifications and the 11th century Clemens chapel, a three-nave Romanesque pillar basilica.

Also Rheinstein castle, the symbol of Rhine romanticism, is located in Trechtingshausen.

Trechtingshausen offers as sportive activities hiking on the trail Rhein Burgen Wanderweg and rock climbing in the nature reserve "Morgenbachtal".
