Construction is Coming:

Work on the new campground will begin in mid-September and is expected to last until late August 2024, impacting area traffic. For safety, construction traffic — including dump trucks and heavy equipment — will utilize Eagle Island Parkway off State Highway 44/State Street; public traffic generally will not be allowed. Keeping construction equipment out of the residential area will reduce conflict and noise impacts.

Park visitor traffic will be rerouted to Hatchery Road/Trout Road off of Linder Road for the duration of construction. Project updates will be posted here throughout the work. The Idaho Department of Parks and Recreation is working with the Ada County Highway District and the Idaho Transportation Department on the project to mitigate the impacts to the greatest extend possible.

Historic Building Renovations:

The park will also be working on historic building renovations. Please be mindful of workers in the area.

Eagle Island State Park in mid-2022 enacted a new policy regarding dogs off-leash and has designated an area and trails that are open to off-leash dogs that are under the demonstrated control of their owners. Click here for details.

New Eagle Island Dog Policy:

Pilot Program Creates Off-Leash Areas and Trails But Requires Dogs To Be Leashed Everywhere Else

The Idaho Department of Parks and Recreation has implemented a pilot program to create off-leash areas within the park, after considering the constructive feedback from the public following a May 12, 2022 open house.

Per state law (IDAPA, dogs must be on a leash at State Parks, but the department has the ability to designate off-leash areas.

Dogs are now allowed to be off-leash on designated, off-leash trails and in the newly designated Dogs Off-Leash Area (please see map) – but only if the owner demonstrates control over their animal(s). Having control of an off-leash dog means the owner prevents the pet from disturbing other park visitors and wildlife, and the owner has the ability to recall the animal at any time.

The 212-acre, Dogs Off-Leash Area will be south of the main access road, and south of the old Slaughterhouse and Warden’s House (blue shaded area on map). Please note that the area remains a working farm, so dog owners can expect flood irrigation. Two areas where dogs have formerly been allowed off-leash, north and south of the Prison Dormitory Road, will no longer be available because of the new campground and associated pond, which will break ground in fall 2022.

  • Off-Leash Area Requirements: Dogs cannot harass people, wildlife or other pets. Owners must carry a leash, waste bag, and clean up after their animal(s).
  • Off-Leash Trail Requirements: An unleashed dog must be within 30 feet of its owner and under voice control. Dogs cannot harass people, wildlife or other pets. Owners must carry a leash, waste bag, and clean up after their animal(s).

Note: Dogs are only allowed off-leash in the Off-Leash Area and on the designated, off-leash trails. In the park’s core area – near the waterslide, the picnic areas, the disc golf course and zipline attractions – dogs must be leashed. The lake and beach will continue to be off limits for canines.

The department will closely monitor the pilot program, which is subject to change at any time. Common sense and respect for others can make this pilot a success. Thank you for your support of Eagle Island and for your efforts to ensure a safe and pleasant experience for everyone.
