In reply to John Ww:
Hi John,
unlikely to find anything in Goslar for climbing, surprised by Hannover though.
Can photocopy the guide for you, includes Marienwand, and Okertal.
Recommend Savage Crag (Fruhgeburt 7+, Schlappe Socke 8, Bermuda Dreiecke 6) and the Grosse Treppenstein (Falkenweg 7-, Holzweg 8?, Direkter N-Pfeiler 7-).
If going to the Marienwand, park at the Dam near the cafe and walk down the road, takes about 10 mins. It does get heaving in the summer and there is usually a queue for some of the routes.
Failing that, look at the crags deep into the forest, wee bit of a trek but worth it, shelter away from the heat.
If you want a copy, drop me a line, great place to go.
