Ashton-Tetonia Trail State Park

Description

The Ashton-Tetonia Trail stands as one of Idaho’s most remarkable rail-to-trail conversions, stretching [nearly 30 miles](https://visitidaho.org/things-to-do/rail-to-trail/ashton-to-tetonia/) through the spectacular Teton Valley. What used to be a bustling railroad line has been transformed into an outdoor enthusiast’s paradise. The trail, which [opened to the public in 2010](https://parksandrecreation.idaho.gov/parks/ashton-to-tetonia-trail/), now offers a unique way to experience eastern Idaho’s stunning landscape.

Key Features

Best Time to Visit

The trail shines brightest from late spring through early fall when the weather is most accommodating. Summer mornings are particularly magical, with crisp mountain air and golden light washing over the valley. Fall brings stunning colors as local vegetation transforms into a canvas of reds and golds. The trail can be accessed year-round, but winter visits require proper equipment and extra precautions due to snow conditions.

How to Get There

The trail connects the charming towns of Ashton and Tetonia, with multiple access points along its length. The main trailheads are located in both towns, with several well-marked parking areas in between. You’ll find ample parking at either end, making it convenient to arrange point-to-point adventures or shorter out-and-back excursions.

Tips for Visiting

Pack plenty of water and snacks – there aren’t many facilities along the trail. Bring bear spray and make noise while traveling, as this is active bear country. Consider arranging a shuttle if you’re planning a one-way trip. The elevation and open exposure can make the trail feel more challenging than expected, so pace yourself accordingly. Bikers should bring basic repair tools and a spare tube. Early morning or late afternoon visits often provide the best lighting for photography and more comfortable temperatures. And don’t forget your camera – the views of the Tetons are absolutely incredible from certain vantage points along the way.

Remember to respect trail regulations – [e-bikes (Class 3), ATVs, and other motorized vehicles aren’t allowed](https://parksandrecreation.idaho.gov/parks/ashton-to-tetonia-trail/info/). The trail’s relatively gentle grade makes it accessible to most fitness levels, but the length can be challenging if you’re planning to cover the entire distance. I’d suggest starting with shorter segments if you’re new to rail-trails or haven’t done much long-distance outdoor recreation.

The trail tells a fascinating story of Idaho’s railroad history while offering a perfect blend of outdoor recreation and scenic beauty. Whether you’re a serious cyclist, casual hiker, or just someone looking to spend a few hours exploring eastern Idaho’s remarkable landscape, the Ashton-Tetonia Trail delivers an unforgettable experience. Just remember to pack accordingly, stay alert for wildlife, and take plenty of breaks to soak in those magnificent Teton views.
