30 minutes · Henry’s Fork country
Island Park: Trout Water, Mesa Falls & Winter Trail Country
Island Park is where the fishing, snowmobiling, and Mesa Falls day trips live. Three Peaks is the private lodge 30 minutes south — one roof for 40, a commercial kitchen, and evenings that aren’t a motel parking lot.

Why Go
Most groups lose the trip to lodging math
The usual Island Park plan looks like this: three cabins on three different roads, someone sleeping on a pull-out couch, and half the group eating cold pizza because nobody wants to cook in a closet kitchen. You came for the outdoors. You spend the trip managing logistics.
Three Peaks flips that. You put the whole crew — family, church group, snowmobile club, reunion — in a 9,600 sq ft lodge on 100 private acres in Saint Anthony. Island Park’s recreation is a short drive north. Your nights are exclusive, quiet, and actually together.
The Destination
What makes Island Park worth the miles
Island Park sits on the Henry’s Fork of the Snake River — famous trout water, Harriman State Park meadows, Mesa Falls overlooks, and in winter some of the best snowmobile trail systems in the Rockies. Guests don’t come here for “vibes.” They come to do something outside.
What they underestimate is lodging for a group that size. Cabin inventories fragment fast. Resort rooms don’t hold three generations. And when the weather turns (it will), you need indoor space that isn’t a hotel lobby.
That’s the job Three Peaks was built for: 10 bedrooms and 1 bunkroom, a commercial kitchen that can feed a crowd, indoor slides and playrooms for kids on storm days, a hot tub and fireplace when the day is done, and parking for snowmobile trailers when winter is the point.
You’re close enough to Island Park to ride or fish hard. You’re far enough south that evenings feel like a private house — because they are.
- About 30 minutes to Island Park recreation corridors
- Henry’s Fork fishing access in season — day trips, not motel shuffles
- Winter: stage snowmobiles and park 10+ trailers on-site
- Sleeps 40 across 10 bedrooms and 1 bunkroom — exclusive use of the lodge
- Commercial kitchen + indoor fun when the weather refuses to cooperate
By Season
When Island Park shines
Summer & fall
Fish the Henry’s Fork, walk Harriman, hit Mesa Falls, and still cook dinner for 30 without fighting over one Airbnb stove. Peak reunion months book early — hold dates before you finalize the picnic.
Winter
Treat Island Park as your trail system and Three Peaks as headquarters. Trailer parking, washer/dryer for wet gear, hot tub after the ride. Many groups mix a Targhee ski day (~1 hour) when powder is calling.

Trip Notes
Practical details before you go
- Drive time is typically about 30 minutes north from the lodge (conditions matter in winter — plan daylight returns).
- Grocery and big supply runs are easier via Rexburg (~15 min) or Idaho Falls (~45 min) before you settle in.
- Fly into Idaho Falls (IDA), rent cars, drive about 45 minutes to Three Peaks, then day-trip Island Park from the lodge.
- Ask Dave about trailer parking and wet-gear space when you inquire for winter.
Drive time from Three Peaks Lodge in Saint Anthony: about 30 minutes.

Why groups base at Three Peaks for Island Park days
Island Park is the adventure. The hard part for reunions, church groups, and snowmobile clubs is keeping everyone together when cabin inventory fragments across three roads.
Three Peaks Lodge — about 30 minutes south in Saint Anthony — gives exclusive use of one private lodge: commercial kitchen for dawn departures, beds for up to 40, indoor play when weather turns, and winter trailer parking when riding is the point.
You’re close enough to fish or ride hard. Evenings feel like a house, not a motel row.
