Introduction

Gate of Death, Devil's Gate, Massacre Rocks -- this natural area nestled in American Falls, Idaho is a land of many names. But don't let these grisly epithets deter you from visiting this seriously stunning region!

Back in pioneer times, the narrow gap in the rock formations which characterize the area proved challenging for brave settlers navigating the unique hazards of the Wild West. So challenging, in fact, that successful trailblazers made their mark -- literally -- on the boulder which is now known as Register Rock. Visitors at Massacre Rocks State Park can take a quick trip to view these centuries-old signatures for themselves or get up-close to the well-preserved remnants of the Oregon Trail within the park.

Though the park is named after a deadly skirmish between native tribes and pioneers along the Oregon Trail, visitors won't find any danger here -- apart from the occasional coyote, that is! Outdoor enthusiasts can fish, paddle, hike or simply sit back and scope out the flora and fauna that calls this biodiverse region home.

Planning a camping trip to Massacre State Park? Whether you're simply stopping over for a night or parking the RV to explore all the geological gems this area has to offer, remember, coyotes live in the park. Secure all food, toiletries, and scented items in an animal-proof locker or locked vehicle, or you just might wake up to an unwanted guest searching for a snack!

Driving

Thanks to the park's proximity to I-86, Massacre Rocks State Park is an intriguing spot for RV travelers to stop over on their excursion through the Gem State. The campground loops are paved, with roads wide enough to accommodate big rigs and regular vehicles. The main parking lot and roads by the entrance are gravel. Note that the park is located in a relatively remote area, although provisions can be found in the nearby town of American Falls.

Parking

Visiting Massacre Rocks State Parks for the day? Park the rig in one of three parking areas and let the adventures begin! The main lot is gravel and rather small, so keep this in mind if visiting during the peak season. Other parking areas can be found just outside the campground, near the Trapper's Trailhead, and by the boat ramp. Note that a vehicle entry fee applies at Massacre Rocks State Park.

Seasonal activities in Massacre Rocks State Park

In-Season

Fishing

If you're a fan of fishing, don't forget to pack the rod and reel in the wagon -- er, campervan. Bass is the catch of the day at Massacre Rocks State Park, but trout and carp are also on the menu. Anglers are advised to use plastic crayfish as bait for the best chance of bagging a big bass!

Boating

When you've had your fill of history, unwind with an excursion on Snake River. Watercraft of all kinds are welcome to hit the water from the park's boat launch. Paddlers can use the separate canoe access point. After a day well spent on the water, park your craft at the dock before heading back to the campsite.

Hiking

The trail network at Massacre Rocks State Park is relatively short, and historically significant to boot. Follow in the pathway of pioneers past, quite literally, on the Wagon Rut Trail, just over three-quarters of a mile long and home to meticulously preserved wagon ruts. Respect this route by taking nothing but pictures and leaving nothing but footprints.

Off-Season

Picnicking

Once your inner adventurer is sufficiently tuckered out, why not refuel with a packed lunch? Picnic areas are located throughout the park along the scenic Snake River. While it may not be the best place to host your next group gathering, Massacre Rocks State Park makes the perfect spot for an intimate family picnic, complete with horseshoe pits and a volleyball court to keep the kid campers happy.

Wildlife Watching

Geese, pelicans, and herons, oh my! Birdwatching enthusiasts will relish the chance to step out of the RV and spend the day spotting some of the park's frequent flyers. If you're lucky, you just might see a bald eagle! Other resident animals include beavers, rabbits, and coyotes.

Disc Golfing

Let the games begin! Treat your camping crew to a little friendly competition on the park's new disc golf course. In the park's own words, "This ain't your momma's disc golf course!" Come prepared for a challenge on this wooded course, but don't worry if you forgot your gear -- rentals are available at the park's nature store.
