Set in the remote northern reaches of Quebec, the 4/20 route offers climbers a straightforward yet engaging trad experience that tests your steady footwork and route-finding skills. This single-pitch climb stretches about 25 feet along a clean band of rock, inviting climbers to move with intention across a slab roughly 20 inches wide. The rock face stands unprotected, encouraging a cautious approach to every move, with no fixed gear to rely on. The nature around La Source patiently watches as you ascend, the quiet stillness only broken by the light rustle of the northern wind.

Approach to this climb requires a mindful trek through the boreal landscape characteristic of the Abitibi-Temiscamingue region, where the rock walls rise subtly from the forest floor. The trail itself is unmarked and demands some navigation skills but rewards those willing with solitude and the satisfaction of a self-reliant climb. With a modest 5.4 R rating, the route challenges climbers to factor in the risk of runouts while moving with deliberate precision over solid but unprotected terrain. This makes it ideal for those building confidence in placing protection and mastering foot placements in less forgiving conditions.

Since there’s no protection available along the route, climbers should come equipped with a solid set of nuts and cams suited to thin placements, ready to trust their instincts and protect sections where possible. The rock remains generally sound, but the narrowness of the climbing line demands focus and respect. Time your climb to capture the softer light of morning or late afternoon when the wall is cooler and shadows dance lightly on the surface, reducing glare and allowing better hold recognition.

For someone looking to expand their trad repertoire outside busier areas, this climb offers a raw slice of northern Quebec’s climbing culture. The one-pitch layout doesn’t demand extensive gear hauling but calls for mental sharpness and steady hands. After topping out, climbers can exit easily via a short downclimb into the nearby forest, where the fresh scent of pine and birch settles after a calm day.

Plan your outing to include warm clothing layers and sufficient water, as remote conditions can cool rapidly once the sun dips low. Respect the fragile ecosystem and ensure all gear and waste are packed out. This brief but engaging route provides a perfect taste of northern wilderness climbing, balancing adventure with a clear focus on practical skills and safety.
