Create an itinerary including Grinnell Glacier
A challenging hike will allow you to see Grinnell Glacier, probably the most famous and certainly the most photographed glacier within the park. You'll be able to see the glacier best if you take the trailhead that is just over 5 mi (8 km) long, with 1,600 ft (480 m) of elevation gain. Most of the hike will take place along watery areas, where mosquitos thrive in warm weather. Dress appropriately and be sure to bring plenty of bug repellent.

  • Beautiful hike. Quite a bit of elevation gain. Recommend you plan your trip well in advance and book your space on the boats from Many Glacier. The boats will cut out 4 miles of the 11 mile trail.....  more

  • One of the best hikes inside Glacier National park. The hike is strenuous and slightly dangerous since towards the end we have to hike along the slopes on ice. We were followed by a group of Grizzly bear and it’s cubs on the trail. It was scary. But the views were just breathtaking and beautifully serene.
  • Aug 2021. The best trail in Glacier. Hands down. Views are spectacular throughout and breathtaking at the top. It’s a difficult trail and long. But so worth it. Sadly, the Glacier will be gone too soon so take the opportunity if you can. The hike is approx 11 miles long round trip from the Many Glacier Hotel. There is an option to take a boat trip to shave off about 1 1/2 miles each way but we walked. The first few miles aren’t hard as you gradually climb up but the last few miles to the top are difficult especially the last 1/2 mile. Well worth the push at the end. Don’t turn around until you get to the top. The hike took a group of 6 a little over 3 hours on the way up as we stopped to take pictures (and take a break). The trip back down took us 2 1/2 hours. Water, bear spray and good shoes are needed. Trail is narrow with steep drop off throughout. You will get water run off from the mountain side so it will likely be slippery in some areas. Leave plenty of time to get back - we saw a number of individuals and pairs heading up around 4:30 and with the sun setting behind one of the peaks, the return trip in dusk or later can be dangerous (wildlife, gravel, slippery sections, etc.). We were fortunate to see a family of mountain goats on the return trip and wisely backed up to a wider section to let them pass as they had the right of way…and also saw a pair of Rams near the top. It is not uncommon to see grizzlies about 1 1/2 miles in - and on the day we went, one side of the trail around Lake Josephine was actually closed when we started because of bears so be alert. Highly recommended.
