Sheridan to Laramie, WY: Epic Road Trip Guide

Driving south from Sheridan to Laramie along I-25 and US-287 takes you through a landscape shaped by millennia of geologic uplift and glacial carving. The 270-mile journey (approximately 4.5 hours without stops) traverses the northern edge of the Laramie Mountains and the high plains of central Wyoming. A historical quirk: this route roughly follows the old Cherokee Trail, used by gold seekers in the 1850s, and parts of the Oregon Trail branch near Laramie. Watch for the subtle swales of wagon ruts still visible in the shortgrass prairie near Bessemer Bend.
