A 7 hour hike will reward you with one of the most incredible alpine lake scenes you'll ever see! Almost nobody knows about this hike, despite such close proximity to Vancouver. What i love about this hike is that you get great views all the way up, looking back over the valley towards Squamish.
You'll need either a 4x4, or a 2 wheel drive that you don't really care about to get up to the trail head. Pack for a full day's hike, take a head torch and cell phone, and be sure to tell someone where you're going.
