Callahan State Park receives more than 100,000 visits each year by a wide range of users, including hikers, equestrians, mountain bikers, runners, bird watchers, skiers, senior citizens, small children and others. Parents with small children need to be aware that more than 85% of these visitors are people with dogs.

The park is open to recreational uses consistent with resource protection. So consideration for others and polite behavior are essential to ensure the enjoyment of all park users.

Off Leash Rules

With off-leash freedom comes responsibility. Please be a responsible dog owner/walker. The existing signs on Callahan’s trails are misleading. These are the facts:

  • On-leash: Dogs are to be leashed in all parking areas and on all trails that abut private property. Dogs must not enter private property – ever!
  • Off-leash: romping is permitted on most interior trails and in the Eagle Pond area.
  • Voice Control: Off-leash dogs must be supervised and under strict voice control.
  • Scoop the Poop: Pick up after your dog and discard the poop bag in a trash barrel (located in all parking lots year round, and at Eagle Pond in the summer months). Do not leave poop bags behind on trails, in the woods, at Eagle Pond, or…anywhere!
