The Ultimate Guide to Wild Horse Island State Park
As a young person, I spent a lot of time on Flathead Lake, which meant that we would occasionally make the trip over to Wild Horse Island State Park. Not only is it one of the best things to do in Kalispell, MT and the Flathead Valley, but it’s one of the most unique parks in the area (and yes, there are wild horses on the island). You will want to keep in mind that the park is only accessible by boat, but if you can make that work for you, then you should absolutely add it to your list of things to see while you’re in Montana.
