No special access issues
Park on either of the parkings. Remember to use the park disc. From the parking head up to the hill side in the direction south west and stay on the obvious wide path, after about 100m the path goes a bit down a "tiny valley", stay to the right of the next "hill" and follow this path for around 50m. Now you should be able to see the first boulder. For easiest access, use the map and stick to the recorded GPS track.
Basic rules of outdoor climbing ethics apply. Leave no trash behind. Brush holds and tick marks. Be friendly to other people in the forest. Keep noise level down etc..
