Island Park is in Fremont County, not far from Yellowstone National Park. It's a place for trout fishing, two state parks and a big groomed snowmobile trail system. Here's a quick local look for anyone thinking about a cabin, a second home or a full-time move.
From Island Park, West Yellowstone, Montana is about 35 minutes away (about 28 miles). Rexburg is about an hour (about 52 miles), and Idaho Falls is about 1 hour 35 minutes (about 80 miles). Drive times are rough estimates for normal conditions; winter weather can add time. If you'll be commuting, try the drive at the time of day you'd actually make it before you commit to a home.
Island Park Charter School, a K–6 public charter school, is in Island Park itself, according to the state's Idaho Report Card. Fremont County Joint School District 215 runs schools in Ashton and St. Anthony, including North Fremont Jr/Sr High School in Ashton and South Fremont High School in St. Anthony. Ask the district which schools and bus routes serve a specific address. You can look up enrollment, programs and contact details for any Idaho public school on the Idaho Report Card, from the Idaho Department of Education.
Harriman State Park lies within an 11,700-acre wildlife refuge in the Greater Yellowstone Ecosystem and has 22 miles of hiking, mountain biking and horseback riding trails.
Henrys Lake State Park is on the shore of the 6,000-acre lake, about 15 miles from Yellowstone National Park. Idaho Parks and Recreation says anglers fish there for cutthroat, brook and cut-bow hybrid trout.
In winter, Fremont County grooms more than 500 miles of snowmobile trails across Island Park, Ashton and the surrounding backcountry, generally December through March, depending on the weather.
The Fremont County snapshot above covers the whole county, including St. Anthony and Ashton, so it's background rather than an Island Park price. Cabins and second homes up here can be very different from one another. Tell us what you're picturing, and we'll pull the recent sales that truly compare. Whatever you buy, a few questions are worth asking early: how old the roof, furnace and water heater are, whether the home is on city water and sewer or a private well and septic system, and how the street or driveway is cleared in winter. We'll help you get those answers before you write an offer.
Thinking about buying or selling in Island Park? We'd love to help, whether you're just starting to look or you're ready to go. Call or text Ali and Josh at 208-271-4250. There's no pressure, just honest answers.
