Nothing much to do haha, it's a veryyy scenic drive there and back. There are a few rest stops by Lillooet that are awesome, you're right by the water and there are tables for you to eat on and enjoy the scenery.
Some more pictures I took while I was by Lillooet, this was at one of those stops where you could eat by the water at. It was kind of like fast flowing rapids
Some very old bridge that's said to have dead human bodies embedded in the rocks or something..
