Emmons Glacier View Trail Professional Review and Guide
"The rewards are grand views, wonderful lessons in geology, and easy hiking. The only drawback of the route is the potential for crowds—the hiking is relatively easy, leading out of a popular car campground, so the masses flock to this scenic trail.
Fortunately, the broad trail can handle the pressure. In fact, it once handled hordes of tourists in Model Ts and Park Service buses, so a bit of foot traffic won’t be a problem. The road-turned-trail offers easy walking for the most part, close to the river. Look up at the hulk of Rainier looming to the southwest as you hike, and you can enjoy the towering wall of Goat Island Mountain to the south."
