The hike to Grinnell Glacier is one of Glacier National Park’s most beautiful hikes. This hike has it all…stunning alpine scenery, waterfalls, emerald green lakes, wildflowers, the chance to see wildlife, and of course, a glacier.

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.

Please practice the seven principles of Leave No Trace: plan ahead, stay on the trail, pack out what you bring to the hiking trail, properly dispose of waste, leave areas as you found them, minimize campfire impacts, be considerate of other hikers, and do not approach or feed wildlife.

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 (before 8 am) 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.

PRO TRAVEL TIP: If you are not staying overnight in the Many Glacier area, try to get to Many Glacier no later than 8 am. Once the parking lots fill, park rangers turn visitors away at the entrance station. This happened during our visit, not to us, but to other visitors.

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.

Big Steps

 

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 had 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.

Glacier Travel Guide

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.

Grinnell Glacier Boat Shuttle

The boat on Lake Josephine.

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.

Boat shuttle map Grinnell Glacier

Map of the hiking trail and boat shuttles. The main hiking trail is yellow. The boat shuttle routes are white. The red lines are the short hikes between the two lakes and the hike to get to the main trail from Lake Josephine.

The ticket price is $35.25 for adults and $17.50 for children (in 2022). This price includes your round trip journey on the boat shuttles. At specific times of day, this also includes a ranger-led hike to Grinnell Glacier.

You cannot book a one-way ticket from Many Glacier Hotel to Lake Josephine. However, if there is availability, you can ride the shuttle one way from Lake Josephine to the Many Glacier Hotel. This really depends on how much open seating these boats have, so you run the risk of walking to the dock and learning that the boats are fully booked for the day.

PRO TRAVEL TIP: Book your tickets in advance because they can sell out. It is possible to purchase your ticket the same morning that you want to do this hike, but most likely you will have to wait in a long line. We tried this, but the line was so long that we gave up and hiked the entire trail instead.

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.

What to Bring on the Hike

  • Food and water
  • Sunscreen. There is very little shade on the trail.
  • Bear Spray

    About how long would it take to hike from where the 2nd boat lets you off to Grinell Glacier? If I take the 2:00pm boat leaving from Many Glacier, would I be able to complete the hike in time to catch the 5:15 return boat?

    Thanks!

      You will have about 7 hours of hiking. If you hike at 2 miles per hour (which is average hiking speed), you will need 3.5 hours. You could make the 5:15 boat if you hike fast and don’t linger long at Grinnell Glacier. Cheers, Julie

        Hi Julie – thanks so much! I take it that you meant 7 *miles* of hiking. Either way, sounds like maybe the 1:00pm boat is a safer bet for me to hike and catch the 5:15 return.

          Oops, yes, you are correct. The 1 pm sounds great. It gives you more time to take your time. It’s a beautiful spot, maybe the prettiest we have seen in Glacier NP, so the extra time will be wonderful. Cheers, Julie
