The circuit (which is 1.2 km long) starts from the parking lot in front of the quarry entrance, following the road to the old exploited area. It passes near the climbing spot and then sneaks to the left, entering the spruce forest, heading to the access road to the quarry. At the junction it continues to the left (on the main road) and here we are at the entrance again.
The marks consist in green spots on the rocks and on some trees. However, the blaze is not so evident all the time because of the lack of the trunks or blocks that could have been marked.
All in all, the trail follows large roads, so it's impossible to get yourselves lost. :)
