Veni-vidi-ski-i... I checked P12 with low expectations and was pleasantly surprised to be able to ski to the Fire Tower with only 4 portages each way.
Spring skiing for sure: ice, obstacles (debris, gravel patches, run off trenches, rocks...) and some leaf-running across shorter bare patches, but also some long stretches of very good skiing, mostly past Wolf trail. The climb up 40 is icy and unpleasant but I've seen it worse and things improve past 38. Best sections a little before Wolf along the beaver pond, and between Wolf and McKinstry, as usual. A thin layer of fresh snow from overnight Thursday slowed things down but provided some nice support in icier sections.
Main portages: top of 40 before 38 (200m); 40 at bench just before 24 (50m); small rise after Blanchet (50m); Wolf (200m). Other smaller bare patches can be walked or stepped across with skis on.
Overall, that's a pretty good ratio for the season.
Gatineau Park is ski paradise! The network of ski trails offer machine groomed skate skiing and classic skiing as well as little groomed backcountry trails. Multiple access points allow skiers to access a variety of terrain and scenery. The NCC offers season or daily pay rates.
