In reply to Kahti:
I translated the approach for you using one of the links I posted. Hope that helps a bit.
Leave motorway A65 at the exist "Edenkoben". Don't stop for wine just yet, although you a driving through "Riesling-county".
At the end of the motorway exit turn right.
Go straight across the first round about (ideally not literally
)
Turn right on the second round about (1st exist)
Carry on straight until you reach a round about at an "Aral" petrol station. Turn left here into the village of Maikammer.
Drive through the town and look out for small brown signs with white font "Kalmit"
The road leaves the town and climbs in serpentines up the hill.
There is a car park in the forest near the top. Park here and walk southward. The footpath (should be a proper one as it is one of the main hiking path up there).
The path basically snakes through the "Felsenmeer" =sea of rocks. So I'm sure you will see boulders.
Please note that it is local tradition to climb without chalk to preserve the rock.
Too bad I have to work
I think if you look at some of the pictures in the pdfs I linked, you will have no issues to find the place. Ideally download beforehand as you may not have signal in the woods.
