Thanks to the excellent description in the guide book, we weren't able to find the ice yesterday. But we had the chance to check out the routes in Parc des Grands-Jardins. And we hiked a trail, just to make sure, it went to the desired climbing crag. So we had a pleasant approach today, without any surprises.
We parked the car at the Visitor Center of Mont du Lac-des-Cygnes. And just accross the road starts the trail.
