Roughly 14 mile hike from Logan Pass to the Loop including the Grinnell Glacier overlook. It is strenuous. Grinnell glacier overlook is an out-and-back spur off the main trail that ascends 900ft in .8 miles... then you have to come back down and begin a fairly steady ascent to the Granite Park Chalet. Good place to rest, buy additional water, Gatorade, snacks. Then begins what is, in my opinion, the toughest part of the hike...a 4 mile decent to the loop that is brutal on the knees. Descending sounds easy, it most definitely is not. It is STEEP and uneven. Bring your hiking poles, they saved me. And don't believe google maps estimated time to traverse this. Took us 11hrs to complete this 14 mile hike with sufficient rest breaks, lunch, etc. Start early, it will also help with parking.
