Old quarry with four steps which are connected with ladders and wire ropes. Nice view. Up to 30 metres high. Many routes are well bolted, but some need additional protection. Some clean routes are there, too. Climbing is restricted because of nature conservation. The allowed areas are marked with arrow signs. Please do not leave any litter there. Camping and fire making is strictly forbidden! A campsite is somewhere near the city of Schriesheim (I saw some signs).
Almost all routes have a solidly bolted ring or karabiner at top for rappeling or for installing a toprope. To minimze the wear of these please use a locking carabiner for toproping and rappel at the end. It is not a bad idea to bring a helmet, because at some routes there are loose rocks.
Coming from Darmstadt/Frankfurt drive highway A5 until exit Ladenburg and then to Schriesheim. You may also drive the B3 to get there. In Schriesheim drive in direction Wilhelmsfeld/Schönau (at a traffic light to the left over a railroad track). Then at the first traffic light turn right into Bismarkstrasse, then the second street left (Bahnhofsstrasse). At the end of this road turn right and immediately left into Kehlweg. Before the road turns right at top you'll see a sign at the left which shows a footpath to the remains of the Strahlenburg (Fussweg Strahlenburg). Park here and walk up to the castle. You don't have to follow this exactly, this only one possibility. Only drive up the hill towards the widly visible remains of the Strahlenburg and walk trough the wineyards up to the parking lot of the castle. You can also drive up there, but on weekends the parking lot ist only for visitors of the castle remains (and the pub of course).
At the parking lot of the Strahlenburg you see a signpost. On this sign is a map, where you can see the quarry already. Walk up the non-asphalt street right of the sign until you see a commemorative plaque on the left. Walk up the steep and stoney footpath between the wineyard and the forest. You will cross a non-asphalt road twice. Stay on this road if you hit it the third time and walk up in the forest until you see a wooden bench on the lefthand side. Turn right towards south on the flat foot path (big one). Walk about 500 metres until you see a sign, some kind of old gate and a path heading upwards to the left. Take this path and walk to the quarry. For those with a GPS here are some coordinates: N49.4745902 E8.6706534 Parking at the Strahlenburg (very limited space, mostly reserver for visiters of the Strahlenburg ruin).
