The Montana State Parks reservation system is up and running. Twenty of Montana's 54 state parks are now in the ReserveAmerica reservation program. Visitors can phone a toll free number or use the internet to reserve a space up to 9 months in advance...or in my "last minute" case ... as close as 2 days before the visit.
There is a $10 processing fee and the call center staff can help with details such as camper size and pre-pay fees. Not all sites at the campgrounds will be on the reservation plan and the remaining sites will be for "walk-in" folks on a first-come, first-serve basis.
The toll-free number is 855-922-6768. The website is and more information about the parks is at the Montana State Parks site at
