The road conditions info is written for summer conditions. If you are going now in early spring, the roads haven’t been graded yet and can be muddy.

Any of the routes up high will start to have snow in October. Early October may still be snow-free in some years but you’ll have to check and see as snow can fall at any time in October – it’s a variable month. If you are prepared with warm and waterproof clothing as well as microspikes and are comfortable navigating without trail markers (which can be covered by snow) October can be an ok month to go as there usually isn’t enough snow for avalanche danger yet. But in October I would stick to trails closed to the valley bottom such as Lost Lake, Rainbow Falls, Riverside, Crater Rim, Cheakamus Lake, Whistler Train Wreck, Brandywine Falls, Ancient Cedars, Parkhurst, and Nairn Falls.

My picks are all in my Vancouver hiking books post – unfortunately there is no one guide book for the area but there are a few that I recommend that cover that region.
