How to Hike to Grinnell Glacier in Glacier National Park

On this hike, we spotted moose, mountain goats, and bear. The wildlife sightings and the gorgeous scenery made this was one of our favorite experiences in Glacier National Park.

Here’s how to do it.

There are two ways to do this hike. The hiking stats listed above are for the round-trip hike from main trailhead on Continental Divide Trail.

You can shorten this hike by taking the boat across Swiftcurrent Lake and Lake Josephine. Taking the boat shaves off 3.4 miles, for a grand total of 7.2 miles of hiking. This is a great option if you are traveling with kids, want to add a scenic boat ride to the hike, or just don’t like the idea of hiking over 10 miles.

In this article, I cover both ways to hike to Grinnell Glacier. First, learn what to expect along the trail, from the trailhead to Grinnell Glacier. Then, learn how to use the shuttle service across the lakes.

How to Hike to Grinnell Glacier 

Step-By-Step Trail Guide

Getting to the Trailhead

The Grinnell Glacier trailhead is located on Continental Divide Trail, the road that connects the Many Glacier Hotel with Swiftcurrent Motor Inn and the Many Glacier Campground. On Google Maps, it is labeled “Grinnell Glacier Trailhead.”

There is a small parking lot here. Get here early (by 7 am although even earlier is better) to ensure that you get a spot. If you can’t get a parking spot, you will either have to park along Continental Divide Trail or at one of the lodges and walk to the trailhead. This could add on quite a bit of mileage and time to your day.

From the Trailhead to Lake Josephine

For those of you planning to take the shuttle boats, this is the section of trail that you will skip.

From the trailhead, it is a 2.1 mile walk to get to the far end of Josephine Lake. It is a mostly flat walk so it goes by fast. For the most part, you walk through a pine forest with nice views of both lakes. This is not the most exciting walk, so if you choose to take the boat shuttles, you really are not missing out on much. However, we did see moose from this part of the trail.

Lake Josephine to Grinnell Glacier

The main trail and the trail from the Lake Josephine boat dock join up at the far end (the western end) of Lake Josephine. This is where the climbing begins and the views really start to get good.

It’s just over 3 miles, one way, to Grinnell Glacier from this point. Three gorgeous miles.

From Lake Josephine, it is a steady, uphill walk to Grinnell Glacier. The higher you go, the more the views open up. On a clear day, this hike is literally jaw-dropping. You stop to take a photo, walk another twenty feet, and stop again. Just when you think the view can’t get any better, somehow, it does.

Here is the trail in photos.

Hiking up alongside this waterfall is the “trickiest” part of the hike. It’s not so bad going up, but coming back down, it can be slippery.

The steepest part of the hike comes right before you get to Grinnell Glacier. You’ll climb several sections of staircases made of giant rocks and boulders. But once you get to the top, it’s a short walk to the Grinnell Glacier viewpoint.

Once at the lake, enjoy the view. This is a great spot for a picnic (just pack out everything you bring in).

Ending the Hike

To finish the hike, return the same way you came. It’s faster hiking back, now that it is mostly downhill.

This is the view looking back to Many Glacier Hotel.

This is when we had our best animal sightings.

About a half mile from Grinnell Glacier, we spotted several mountain goats at different locations along the trail.

Not five minutes later, as we rounded a bend, a black bear and her cub walked right up onto the trail.

The trail was very busy now. It was approaching midday and there just happened to be a park ranger leading a large group on a hike out to Grinnell Glacier. At the advice of the park ranger, Kara and I joined their group and backtracked at least a quarter of a mile back to Grinnell Glacier. After a brief wait, and yet another mountain goat sighting, it was safe for us to continue on our way.

What a thrill to see so much wildlife in such a short period of time. But you must always be on alert for bear when hiking in Glacier National Park, even on a crowded trail. Keep up a conversation, carry bear spray, and keep a lookout for bear, not only in front of you on the trail, but also in the brush and the trees along the trail.

Using the Boat Shuttles

The boat shuttle consists of two separate boats: one from Many Glacier Hotel that crosses Swiftcurrent Lake and a second shuttle that crosses Lake Josephine. These shuttles are operated by Glacier Park Boat Company.

From the Many Glacier Hotel, you will take the shuttle across the Swiftcurrent Lake, a journey that takes about 10 minutes. Disembark this boat and walk 0.2 miles to Lake Josephine. Board a second boat and then it is a 12-minute ride to the far end of Lake Josephine. From the boat dock, you will walk 0.4 miles to the main trail to Grinnell Glacier.

There are three options: out-and-back from Many Glacier Hotel to Lake Josephine to Many Glacier Hotel, out-and-back from Many Glacier Hotel to Lake Josephine to Many Glacier Hotel plus a guided hike to Grinnell Lake, and a one-way ticket from Lake Josephine to Many Glacier Hotel.

All tickets must be purchased in advance. You will not be able to purchase a ticket at the last minute for the one-way trip from Lake Josephine to Many Glacier Hotel. It’s best to purchase your tickets at least one day in advance because they can sell out. Learn more on the official website.

Important Note: If you don’t want to hike with a big crowd, skip the boat shuttle and start your hike early. The first shuttle leaves Many Glacier Hotel at 8:30 am, so these hikers join the main trail between 9 and 9:30 am. We were able to stay ahead of the crowds on the way out to Grinnell Glacier, but we saw them on our hike back to our car. And crowds can be huge. This is a very popular hike in Glacier National Park.
