The only nightlife you should be interested in when surrounded by so much natural beauty is the nightlife around a roaring campfire under the stars. If you're musical then break out your guitar and start strumming the tune to "Stairway to Heaven", or roast some marshmellows as you nurse a good Canadian beer by the fire.
Dress Code: No 3 piece suits, slacks, or techno.
Don't forget to look up at the night sky when it is clear out.
Excellent opportunity to view the heavens at a high elevation. It makes a big difference!
