We participated in this activity and found it too late that it's not a hike, it's just a ride to a lake. Keep this in mind. Both guides were nice and friendly, safely picked us up and brought us back at the front door, and the food around the campfire was also fine. But the trip was less informative in itself and we had to ask for the information, which was a pity. Also, the campfire takes place in the tipi - you don't freeze, yet it can get a little smoky.
So despite everything, I can't give more than 3 stars.
