Hi Ray,
Here is information from the state park:
Yes, dogs are allowed at Fremont Peak State Park but are not permitted on park trails. Dogs must be kept on a leash no longer than six feet at all times and must be cleaned up after. Pets are allowed in developed areas like campsites and picnic areas but cannot be left unattended.
You can bring your dog to the outdoor area around the observatory as long as you follow the park rules. However we do not allow dogs inside the observatory building including the lecture room.
Thanks for your interest in FPOA and hope you can make it on October 15.
