Travelers who want to take a step into Montana’s past should take a trip to Wild Horse Island, a state park on the large island in Flathead Lake. The Salish-Kootenai once pastured their horses on this primitive island, and five wild descendants of those animals remain today, along with bald eagles, bighorn sheep, and other iconic North American wildlife.

With extensive trails, rare and beautiful plants, and a scenic shoreline, the 2,200-acre island is a must-visit for visitors to the Flathead Valley. Montana may be most known for nearby Glacier National Park, but Wild Horse Island is proof that there’s much more in the state deserving of your vacation time.

How to get to Wild Horse Island, Montana

Wild Horse Island State Park is exclusively accessible by boat. There are six designated boat landing sites (Skeeko Bay is the most widely used) plus public beach sites where boaters are welcome to pull up. All the island’s docks are private and cannot be used by day visitors.

Guests can either bring their own boats to Flathead Lake (remember that you’ll need to stop at the state’s checkpoints upon entry to Montana to check for hitchhiking invasive mussel species), rent a boat at various locations around the lake, or book a shuttle service from the nearby town of Big Arm to the island. Hiking and walking are the only ways to explore once you’re on Wild Horse Island; even bikes are prohibited.

When to go

Montana’s Wild Horse Island is open to visitors year-round; however, winter presents certain logistical challenges for access, including the fact that Flathead Lake is usually frozen over and boat rental and booking options are unavailable. The shoulder seasons are the best time to visit for balancing comfortable temperatures with reduced crowds, but summer remains the most popular time to go.

As the name suggests, this island is home to wild horses, but it’s also rich with other wild animal species. Bighorn sheep, mule deer, bald eagles, and waterfowl are some of the other creatures visitors can expect to see. While some sources will claim the island has no bears, there have been sightings of at least one resident bear in the past few years, so do come bear aware. Remember: it’s illegal to approach within 100 feet of any wildlife, including the horses.

Wild Horse Island is home to one of the last short-grass prairie ecosystems in Montana, despite the non-native grass species introduced by homesteaders in the 1900s. There is also an old-growth ponderosa pine forest on the northern side of the island. In late spring, expect to see photographers out capturing shots of the bright yellow arrowleaf balsamroot and other vibrant wildflowers.

Camping is not allowed in order to protect the wildlife, but visitors are encouraged to take advantage of the four miles of established hiking trails, though visitors can also explore off trail. The two main trailheads are near the Rocky Bar and Eagle Cove boat landing sites, and the trail system connects the two.

Fishing

There is abundant opportunity for fishing on Flathead Lake, including from Wild Horse Island. Expect to catch lake trout, whitefish, kokanee salmon, and rainbow trout, among other species. Make sure to read up on current regulations for catch and release.

Fishing on Flathead Lake is managed jointly by Montana’s department of Fish Wildlife, and Parks, and the Confederated Salish and Kootenai Tribes, so visitors need both state and tribal permits to legally fish these waters. If you don’t plan to eat what you catch, consider donating them to local food banks or community kitchens. You’ll need to buy a tribal fishing permit in person at one of the many tackle shops around the lake.

Where to eat and drink

It’s best to bring your own provisions as there are no restaurants or food options anywhere on the island, and creating a fire of any kind is prohibited. However, visitors are free to forage apples or pears leftover from orchards planted on the island in the early 1900s. Fishing with the proper permits is also allowed, though catches will need to be cooked elsewhere. There’s a vault restroom along Trail 2.
