This is what all gravel trails should aspire to! A good, long, pristine gravel trail with some surprising twists and turns, scenic mountain views and full of history. Along the way, the trail is marked with kiosks that provide information about the area’s history and environment. Well worth the stop at each. We have not marked all the kiosk sites on the map below; instead, we recommend that you print or shoot a photo of this map.

This ride was even more fun and enjoyable than we expected. Though close to the highway, the trail quickly draws you into wide meadows, shaded forests, and sweeping mountain views, making the outside world fade away.

Highlights & Remarkable Spots

Sawtooth National Recreation Area

Cyclists in Sawtooth National Recreation Area, ID

Established through bipartisan effort in 1972, the Sawtooth National Recreation Area covers 756,000 acres of incredible wild lands. National Recreation Areas are loosely defined as an area of terrain (land or water) that has been protected by an act of Congress due to the area’s natural resources, scenic attributes, and recreational opportunities. While there is no one set of laws guiding the management of these areas, the main intention was designed to get Americans out onto their public lands for recreation and enjoyment.

Sawtooth Visitor Center/ ~ Start/End

The Sawtooth National Recreation Area Visitor Center features a wide range of engaging informational services, including video presentations, audio tours, natural history exhibits, and informational kiosks. With parking, bathrooms, exhibits, and a gift shop, this is a great place to start/end your ride.

Boulder Peak View/ ~ Mile 5

Boulder Peak comes into view along the route. At nearly 11,000 feet in elevation, Boulder Peak is the most visible of the Boulder Mountains. The area drains to the Big Wood River via creeks like Boulder Creek. While it is only the 127th tallest peak in Idaho, it is steep and rugged and provides a stunning view into the deep wild areas of the Sawtooth National Recreation Area.

Easley Hot Springs / ~ Mile 7

Open seasonally from Memorial Day to Labor Day, Easley Hot Springs have soothed aching muscles for a very long time. Originally dug out by John V. Easley, there was a log house to provide miners a place to stay and clean up. With the decline in mining, the hot springs fell into disrepair. Then, in 1919, a Baptist Convention noticed the hot water in the river, and eventually petitioned the Forest Service for a permit in order to rebuild the facilities. Over the next century, Easley Hot Springs has seen many renovations as time and nature have taken its tolls. Nevertheless, it’s worth a stop to feel the warm water.

Galena / ~ mile 19

Founded as a mining town in 1879, Galena served the Wood River Valley with several hotels, stables, a meat market, and the Daisy Saloon. But when the veins of ore dried up in the 1890s, Galena was abandoned and left virtually a ghost town. In the early 1900s, with interest in outdoor recreation growing, the Galena Store served folks coming to visit the “Switzerland of America.” It became a Lodge in the 1960s, catering to skiers and other visitors. Continuing this tradition today, Galena Lodge offers guests a quiet place to enjoy the scenery, eat good food, rent gear, or stay overnight.

Pioneer Mountains View/ ~ Mile 29

The Pioneer Mountains are home to America’s first Backcountry ski hut. Built in 1937 by Averell Harriman, the Pioneer Cabin was modeled after the high-country touring huts used in the European Alps. Around the same time that the cabin was built, Harriman also began construction of Sun Valley Lodge and Resort, complete with groomed trails, and the world’s first modern chair lifts.

Late spring and early fall are ideal. In late May, when we rode this, the wildflowers were in bloom, the trail was free of snow, and the Big Wood River was running strong.

In the early fall, the early miles of the route would be spectacular with the change in the color of the leaves of the Cottonwood and Aspen trees.

Terrain & Riding

The Harriman Trail winds gently through the heart of the Sawtooth National Recreation Area, following the Big Wood River beneath towering peaks. The trail is dirt and gravel double track that rolls fast climbing gradually all the way to Galena Lodge. You will encounter wide-open stretches and pass through shady forest corridors. The views shift between alpine meadows and rugged ridgelines. It’s feels both expansive and intimate.

Notes & Options

Route Options

If a 38 mile ride is not what you’re interested in, there are many options to choose from.

For a shorter option, we like parking at the Baker Creek Rd on the north side of Highway 75 (coordinates: 43.784161, -114.556546). There is a pit toilet and ample parking. You’ll cross over highway 75 to get to the Harriman Trail, and then it will be a 20 mile out and back ride to Galena Lodge.

For a longer option, and more of a climb, there are 2 trails that take you up to Galena Pass Summit. The Titus Lake trail is a single-track on the south side of the road, and the Galena Summit Toll Rd is a single-track on the north side of the road. For more information about the trails around Galena Lodge, check out this map.

The Harriman Trail exists because public agencies and local groups joined forces—but their resources are stretched thin. Stewardship cannot be left to them alone. It belongs to all of us.

As riders and trail users, we each have a role to play: give your time by volunteering, share your talent to strengthen trail programs, or contribute your money to support those doing the day-to-day work. Organizations like the Wood River Trails Coalition and the Blaine County Recreation District depend on our involvement to keep this place open and thriving.

We’re asking every Dirty Freehub community member to give back one hour for every ten hours you ride. It’s simple. It’s doable. And it matters. The Harriman Trail offers us beauty, connection, and joy—let’s return the favor with our time, energy, and support. Together, we can ensure this trail thrives for years to come.

Make sure you leave some time to visit the Sawtooth National Recreation Visitor Center (check hours by calling (208-727-5000). Here you will learn about:

The Tukudeka (Mountain Sheepeaters): A band of the Shoshone, the Tukudeka were known for their deep connection to the mountainous terrain, subsisting on bighorn sheep and other native resources. Their name translates to “Eaters of Mountain Sheep,” reflecting their primary food source. Today, their descendants are part of the Shoshone-Bannock Tribes of the Fort Hall Reservation in Idaho and the Eastern Shoshone of the Wind River Indian Reservation in Wyoming.

Beavers, black bears, bobcats, elk, moose, mountain goats, mule deer, and the reintroduced gray wolves.

Trees along the ride including Douglas fir, lodgepole pine, subalpine fir, Engelmann spruce, cottonwood, and aspen.

Wildflowers along the ride like lupine, fireweed, elephant’s head, and alpine forget-me-nots.

And endemic and sensitive species unique to the region, including the Stanley Whitlow Grass , Stanley Thalaspi , and Guardian Buckwheat.

Bigwood Bread and Cafe, Ketchum, Idaho

Keep it Local!

Ketchum is a small town with a big town food scene. From casual burgers to fine dining Italian, you’re sure to find what suits you. We like Bigwood Bread for an amazing breakfast and lunch selection. Grumpy’s is definitely “home of the best damn burgers in town!” And the pizza, wine, and pesto asiago meatballs at Enoteca create a cozy upscale experience.
