Overview: This is one of the most beautiful hikes in the entire National Park. The wonderfully maintained park trail will take you past beautiful lakes onto steep hillsides with sweeping views of waterfalls and glaciers all around you. You will probably see a lot of wildlife on the trip as well so be ready with your camera. When you get to Grinnell Lake you will see icebergs (no joke) floating in the lake from the rapidly retreating Grinnell Glacier. It is not advisable to walk on the glacier as there are crevasses but if you are careful and are there during the late summer the crevasses should be very visible and you can take a very cautious stroll onto the ice as I did in the gps track in this guide.

Tip: Please see the linked site to this guide before going on this hike. It will be worth it. If you can't find the link just go to Wikipedia and type in Grinnell Glacier to see how the glacier has changed over the past 75 years.


Tips: Grinnell Glacier Trailhead Directions:
From the park you will need to take the Going to the Sun Highway north through the entire park to the small town of St. Mary and the intersection with Route 89. Follow Route 89 north to Babb and then take a left onto the Many Glacier Road. Follow that road to the end and find a place to park. I don't believe there are parking fees for day hikes. Just before the official end of the road you will see a parking area for the trail. Use the gps track in this guide as a reference.

There is a $20 fee to enter the park last time I checked.

Views From Above Grinnel

During this mile or so stretch of the trail you will be blown away by the views. I'm not going to put a sepearte POI for each viewpoint as there are so many but will include all the photos here of the amazing views you will see along the way. The turquoise blue of the glacier water is just amazing. Your destination will be the source of the water flowing over the edge of the glacial cirque at the head of the valley.

Upper Grinnell Lake

This is just an amazing area. From the satelite image you can see how the glacier has left folds of rock behind as it has retreated uphill draining into the glacier lake below it. I (the writer of this guide) got my masters degree researching the retreat of glaciers in the western U.S. I urge you to please please look at the linked Wikipedia page I've put in this guide to see the unbelievable retreat this glacier has undergone in just the past 75 years. It will blow your mind.

Venturing onto the Glacier

Again, this is not advisable during any season besides deep summer or early fall before any snowfall as there may be hidden crevasses you could fall into = death. Be very careful as the ice obviously is slippery and stay far away from any edges if you decide to try this. Also - DO NOT DO THIS ALONE. When you are done exploring and taking photos head back out the same way you came. I almost walked directly into a big horn sheep around a corner on the way out so keep your eyes open!
