I will have a work trip in Whistler, British Columbia, Canada early June, and I'm seeing if I can combine this with a backpacking trip in the nearby coast mountains for 2–3 nights. However, it's very early in the season and from the presence of big glaciers I deduce the Coast Mountains are very snowy, so I expect alpine routes in e.g. Garibaldi Provincial Park will be inaccessible due to deep snow, perhaps down into the forest.
What are some backpacking trails in the area, that are accessible in the spring/summer shoulder season (early June)? As I have only 2–3 days, I don't want to be more than 2–3 hours of travel from either Whistler or Vancouver. I prioritise solitude over having the most spectacular scenery.
