Eagle Island State Park

PARK UPDATE:

Know before you go: Flush restrooms, sinks, and drinking fountains at Eagle Island State Park are not currently available. Portable restrooms and handwash stations are available. Visitors: Please bring your own drinking water. This information will be updated and is current as of April 19, 2025.

Construction Update:

The Idaho Department of Parks and Recreation will close the entrance from Linder/Hatchery Road at Eagle Island State Park on Tuesday, April 1, returning park operations to the original configuration utilizing the main entrance from State Street.

The Linder/Hatchery Road access point was opened to support construction activities and ease traffic during the campground expansion project. At this phase of the project, the Park will resume using its primary entrance on State Street. Visitors will need to use the State Street entrance going forward and the Linder/Hatchery Road entrance may be opened for events or other Park needs in the future.

Please be aware that construction is still on-going and we ask that all visitors be careful and follow the signage and the speed limit.

The shop road/horse trailer access road is currently closed but will reopen when it is safe to do so. We ask that horse trailers please use our overflow gravel parking lot for the time being!

The park’s water slide will remain closed and is scheduled to be removed in 2025. Originally constructed in 1983, it has been idle since 2023 due to equipment failures, which now make it unsafe to operate. Fixing the equipment will cost too much to be feasible, given the age of the structure.

Park management is evaluating alternative uses for the space once the waterslide is removed.

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.
