Starting Point: Bison Viewpoint

At the start of the trail, you may see the small herd of bison, that has been an attraction to the area since 1920. The original herd came from Yellowstone National Park and Wichita Mountains National Wildlife Refuge.

For your safety, please do not enter the fenced area.

The trail is a loop that leads you through prairie grasslands, lush stream bed growth along Rock Creek and mixed deciduous forest. This contrast is especially noticeable when you take the Bromide Hill branch and ascend to one of the highest points in the area. Bromide Hill, also called Robber's Roost because of its alleged use by outlaws in the early days, rises 140 feet above Rock Creek and gives a panoramic view of the Platt Historic Area. From this point the town of Sulphur lies to the north, the Rock Creek corridor winds south to the Arbuckle Lake, and the remnants of the Arbuckle Mountains rise in the west

Also accessible from this loop is the cutoff to Rock Creek Campground. The campground is open year round and provides many well shaded camp sites.
