Brilliant, top 5 hike for me. We had some laughs and I am sure some swearing while crossing the endless Garibaldi Lake, but overall a fantastic adventure with a wonderful group of people.

Conditions: We crossed the lake on micro spikes and returned on snowshoes only because the sun was softening it a bit and it seemed an easier go... skiies would be your best bet, faster and safer too... but it is going to be solid for a few weeks even at these temperatures I would think.
The Lesser Garibaldi and Barrier Lakes... definitely stay off of them.
Have fun out there, stay safe and see you on the trails!
