In reply to Adrien:
Hi,
Not having a second makes the logistics quite a bit harder in some (most) routes, because the rappel stations can be on the other side of the towers.
Dahn is good.
Other things to do: go to a Weinhof (https://www.pfalz-info.com/die-deutsche-weinstrasse/) and try the wine... Bad Bergzabern is a nice small town, also Trifels.
For cracks you are in the right place. Good ones are:
Jubileumsriss (Nonnenfels) (rappel over route possible)
Grosse und Kleine Suedwandriss (Pferdfechtfelsen) (don't remember the descends)
Goetterverschneidung (Fladensteine) (rappel over route possible)
Grosse und Direkter Suedriss (Fladensteine) (rappel over route possible)
Grosse Suedverschneidung (Backelstein) (don't remember the descend)
Schnappsweg und Falkendach (B. Geierstein) (rappel over route possible)
Lots at Hochstein and Asselstein (don't remember the descends)
If those are too easy, try Rote Wand at Backelstein
Easy and fun:
Braut und Brauetigum
Byzantinerweg (Hundsfels) (definately needs a second, but only III)
Normalweg (Hochstein)
