Campers wishing to reserve a campsite can make a reservation up to six months in advance for arrival dates of May 15 through October 15 by calling 1-877-444-6777 or you can make your reservation online.
Platte River Campground is open year-round and offers a wide variety of camping styles. You can find back-in and pull-through sites for RV's, including electrical hookups; but it also offers beautiful tent sites, walk-in sites for the slightly more adventurous, and group sites (hike-in, tents only) accommodating up to 25 people. There is even a nearby backcountry campground for those who enjoy a great backpacking experience, but don't have the time to head for the Manitou Islands.
