Boiseans have a wonderful resource for fun almost at their fingertips. Eagle Island State Park is located just a few miles outside of Boise. Activities here are plentiful: fishing, swimming, horseback riding, disc golf, hiking, zip-lining, or what we did on a recent Sunday afternoon…picnicking.

The Crowd Situation

Rating: 2 out of 5.

This park is busy in the summertime. Expect lots of people. Finding a place to park may be difficult on the weekends. I recommend you start early or choose late afternoon/evening to avoid the crowds. There is a huge parking lot, but I suspect it gets full on busy days.

In winter this park is still used, but is much less frequented. So maybe 4 stars in the cooler months.

Unique to Eagle Island State Park

Where else can horseback ride, zip line, and go on a waterslide all in one location? It’s a weird conglommeration of activities.

The park is quite large, around 550 acres. With that much room, you can fit in a lot of different ways to recreate.

A Little History about Eagle Island State Park

This place has a fascinating history. In 1929, the land was purchased by the Idaho State Board of Prisons. For the next 50 years or so, prisoners lived here and worked on a farm/dairy/slaughterhouse (Crazy, right?!)

In 1983, Eagle Island State Park was dedicated as a state park. The prisoners had moved out several years before.

Our experience(s) at Eagle Island State Park

Picnicking at Eagle Island State Park

We stopped at a grocery store close to the park and picked up some food for a picnic before entering the park. We weren’t dressed for swimming so instead we just put out a blanket and watched as families set up barbecues and splashed around in the beach area.

Taking it easy at the Park


For $5 per car load (zip line not included), Eagle Island is a great option for families in Boise to get outside. With the plentiful activities available, there really should be something to entertain everyone.

We visited Eagle Island State Park as part of our Idaho State Parks Challenge. The challenge consists of visiting all of Idaho’s state parks in one year. We made up this challenge to see a bit more of our beautiful state and help alleviate the restlessness caused by Covid-19 travel restrictions. Feel free to join the challenge!
