The townscape of Sonnenberg is characterized by the castle complex with a climbable keep and picturesque castle garden, where summer festivals and castle festivals take place every year as part of the Culture Days. For the Sonnenberg district, the Goldstein Valley is the local recreation area on the doorstep, which is also an important destination for hikes with its excursion pubs. The Rambach system provides an almost continuous green link on foot to the open countryside and forests of the Taunus.
