Hike the Cinder Flats in Garibaldi Park

Enter from the Cheakamus Lake side, which mean a steady climb up the Helm Creek Trail, but you won't battle the crowds coming up the Rubble Creek side. Plan for a full day in the mountains - it's ~25k total with quite a bit of climbing in the beginning. Bring lots of water, as it can get pretty hot once you're out of the trees! If you want to turn it into a multi-day, the Helm Creek Campground is a fantastic place to set up for the night, 9.5k from the trailhead.
