Eagle Island State Park has 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.

Attention Visitors:

Park staff will be conducting hazardous tree removal and clean up at Eagle Island State Park beginning November 14-17, 2022

The decision to remove the trees in question was arrived at while working through the hazard tree assessment process that is used to identify potential hazards and maintenance issues related to tree health in the park. The trees that will be removed are at the end of their life, have been stressed due to disease, and are located in areas that present a hazard to the public or the facilities of the park. To ensure visitor safety and allow park staff to complete this important project please do not enter work areas during the tree removal and cleanup process.  

For additional information please contact the park at or by phone at 208-939-0696

Pet restrictions are now in place at Eagle Island State Park. But there are still places to take your dog.

For Your Health

For your health, and to keep this popular recreation area open and accessible for your enjoyment, the Idaho Department of Parks and Recreation (IDPR) has adopted a “no pets in the lake” policy at Eagle Island State Park.

Pet feces (direct, on fur, and paws) is a major cause of harmful bacteria in recreational waterways.

  • Keep pets on a leash when in the park
  • Always pick up pet waste
  • No pets allowed on beach or in lake

Stay Safe

Here are some additional ways to protect yourself, your family and the places you like to recreate:

  • Use swim diapers
  • Never swim when you’re ill
  • Shower or dry off with a towel after swimming
  • Don’t feed the geese or ducks
