AAA Editor Notes
Massacre Rocks State Park is off I-86 exit 28 at 3592 N. Park Ln. Once a popular stop along the Oregon Trail, this area along the Snake River is rich in pioneer and geological history. Travelers called the rocky gorge “Devil's Gate” and “Gate of Death” as it seemed a likely spot for an ambush. Inscriptions made by Oregon Trail emigrants can be seen at Register Rock, 2 miles west of I-86 exit 28.
The 1,000-acre state park offers six hiking trails. One leads beneath the freeway to Oregon Trail ruts. Guided interpretive programs are offered summer weekends. Canoe and kayak rentals are available, and two disc golf courses are on-site.
The large boulders scattered about the area were deposited by the Bonneville Flood, a months-long deluge that occurred 14,500 years ago that drained much of ancient Lake Bonneville, the predecessor of Great Salt Lake.
Pet friendly (call for restrictions/fees.). Recreational activities are permitted. Camping is permitted. Picnicking is permitted. Time: Allow 1 hour minimum.
