Poisson Blanc regional Park is a must-see destination for climbers looking for a unique setting to ascend. What sets it apart? You can only access the crags here by boat. Most of the routes start right in the water, and you literally climb right out of your canoe. On top of that there’s a huge variety of climbing, from deep-water solo to multi-pitch trad, and it’s all dotted by campsites on the surrounding islands and peninsulas. Book a campsite, rent a canoe, set up camp, and then spend days paddling right to the wall of your choice, rising directly out of the deep waters of the réservoir.
