My family is always looking for a good road trip — one that combines education with outdoor recreation. We want to learn and have fun doing it.
If you’re seeking a road trip that combines the allure of history, the wonders of nature, and a bit of adventure, Idaho’s Pioneer Historic Byway is the perfect destination.
Spanning approximately 127 miles through the southeastern part of the Gem State — from Franklin through Soda Springs to the Wyoming border— this scenic route retraces the paths of early pioneers and presents a remarkable tapestry of Idaho’s past and natural beauty.
Buckle up and join us as we set out on a journey along the Pioneer Historic Byway, exploring captivating stops along the way.
1. Franklin Historic District
Our journey begins in the Franklin Historic District, Idaho’s oldest permanent European settlement. This well-preserved town exudes a quaint charm, with a collection of historic buildings that offer a glimpse into the past. Delve into the town’s pioneer history at the Franklin Relic Hall Museum, where artifacts and exhibits narrate the stories of the intrepid settlers who established the town in the mid-1800s.
2. Preston
Continuing along the byway, we reach Preston, a delightful small town with a warm welcome. Visit the Oneida Stake Academy, which is the oldest surviving Latter-day Saints church-sponsored education building. If you are feeling more inspired by pop culture than history, you can see many of the spots used in the filming of Napoleon Dynamite, including the Napoleon Dynamite house (which is privately owned, so please be respectful and don’t trespass).
3. Bear River Massacre Site
As we journey further, we arrive at the Bear River Massacre Site, a place of somber historical significance. This site commemorates the tragic event that occurred in 1863 when the U.S. Army clashed with the Shoshone tribes, resulting in one of the deadliest Native American massacres in the country’s history. Take a moment for reflection amidst the serene surroundings.
4. Red Rock Pass
Nature takes center stage as we venture through Red Rock Pass, a geological wonder that bears witness to millions of years of natural processes. Red Rock Pass is at the outlet of ancient Lake Bonneville. There are interpretive signs at the bottom of the hill that describe the ancient geology and how early Latter-day Saint leaders designated it as the northern edge of the proposed State of Deseret. Climb the 73 steps to a memorial to Mormon soldier Joseph Hunt and an incredible view.
5. Niter Ice Cave
The Niter Ice Cave is beneath the earth’s surface and once provided refrigeration of the farm above it. This unique cave provides a cool respite from the summer heat. Be sure to bring a light as it is quite dark not far from the entrance.
6. Soda Springs Geyser
You don’t have to go to Yellowstone to see hot springs and geysers. The Soda Springs Geyser was formed when a drill struck a carbon dioxide gas chamber 315 feet underground. It’s now on a timer and erupts hourly. The geyser propels water up to 100 feet in the air, creating a mesmerizing spectacle against the backdrop of Soda Springs.. From Soda Springs Geyser, you can walk to several other mineral springs: Octagon Springs, Hooper Springs, and Lover’s Delight.
7. Grays Lake National Wildlife Refuge
Nature enthusiasts will find solace in the Grays Lake National Wildlife Refuge, a haven for diverse bird species and wildlife. This protected sanctuary offers excellent opportunities for birdwatching.
Bonus Stops on the Pioneer Historic Byway
Lava Hot Springs, Bear River Hot Springs, and Maple Grove Hot Springs: As a special treat, take a detour to one of three hot springs resorts within a few miles of the Pioneer Historic Byway. Unwind in natural hot pools, have fun on water slides, and soak away your cares amidst stunning natural settings.
Beyond the historical significance of the Pioneer Historic Byway, the route offers stunning vistas and diverse landscapes. As you traverse the path, you’ll be treated to picturesque views of rolling hills, towering mountains, lush valleys, and pristine waterways. The byway’s charm lies in its ability to transport you through time while simultaneously captivating you with the beauty of Idaho’s unspoiled nature.
