May 30, 2024 Construction Update:

The main park entrance off Highway 44/State Street will reopen June 4th, 8 a.m., about a month ahead of schedule. But this is a temporary reopening, lasting through July 7th, and will end to allow the completion of a water-line-and-paving project on the entrance road. During this time:

  • The secondary entrance off Hatchery/Linder roads will remain in operation.
  • The entrance road will be gravel, and the posted speed will be 10 mph.

The main entrance is expected to open permanently by early October, at which time the Hatchery entrance will again be closed.

Attention Park Visitors: Please adhere to trail closure signs during the construction process. 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!

Note: The completed campground will not impact trail areas, this is only temporary while work is being done. Thank you!

The park’s water slide will remain closed and is scheduled to be removed later this year. 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.
