Eagle Island State Park is a must-see!
This is a huge 545-acre park west of Boise. Bordered on the north and south by the Boise River, Eagle Island features a swimming beach, grassy picnic area and more than five miles of trails for horseback riding, hiking or just walking. They have a water slide that opens Memorial Day weekend and is open generally until Labor Day.
In the winter, they have snow hill with inner-tubing too!
Autumn is family photo time and many families find the old farm buildings along with rustic river scenes to be idyllic for just such occasions.
All year round, there is a 19-hole disc golf course, pavilions, playgrounds, and quite a bit of learning opportunities.
