Wild Horse Island State Park

Located on Flathead Lake, Wild Horse Island is the largest island in a freshwater lake west of Minnesota.

While most of the island is a state park, be aware as there is still private shoreline, therefore visitors are prohibited from using the boat docks.

Wild Horse Island is said to have been used by the Salish-Kootenai Indians who would pasture their horses on the island to prevent them from being stolen by other tribes!

Wild Horse Island used to be farmed and in the 30s even hosted a lodge. Visitors can still find apple and pear orchards, so if you’re feeling peckish, grab a snack!

The island even has a Palouse Prairie ecosystem, one of only three of these biomes in Montana!

Did You Know

Curious what other visitors have had to say about the park?

"Beautifully untouched for the most part. There are 5 horses currently on island and 1 bear, that we saw neither of. Lol. However it was abundant with bald eagles, osprey, deer, and bighorn sheep. Most of which you can view from a boat offshore if you have a keen eye. If not get a guided tour. But no tours are given on island, just to and from."

"Great place to boat to and relax. Beautiful water and fun rocks to skip!"

"Beautiful island to cruise around and we caught the 5 wild horses on the Western side!"

"Island in flathead lake with a few hiking trails and animals. Worth a visit during the day, or coming over by boat closer to dusk to see the deer, sheep, and possibly horses as they come down to drink."
