Would you rather spend a day on the lake or a day in the mountains? Being from Minnesota, I have to choose a day on the lake, but my favorite thing about Glacier National Park is that you don’t have to choose!
Aside from hiking, The Crown of the Continent is perfect for kayaking or boating on Lake McDonald, the largest lake in the park. If you plan to check out this park in the summer, here are a few things I’d recommend:
- Get there early, or make your reservations in advance, especially for water activities. I ended up using a kiddie kayak because this was all they had left by the time I got there.
- Check the trails ahead of time. A lot of hikes I wanted to do were closed due to bear activity or unsafe conditions on the trail, so make sure the route you have planned is actually open to the public.
- Plan to spend between three to five days exploring Glacier. I only had time for two days, and I wish I had dedicated more time to this park as there’s really just so much amazing scenery to explore!
Do note that many of the mountain passes close from fall to spring, so make sure to check ahead of time what's open if you're planning to visit outside of the warmer months.
