Scenic Drives > Lewis and Clark Back Country Byway and Adventure Road (ID) 
Location
A 39-mile loop road beginning and ending in Tendoy, Idaho, which is 141 miles northwest of Idaho Falls and 20 miles south of Salmon.
 
Description
The byway winds its way up to the Continental Divide through the scenic Beaverhead Mountains of the Bitterroot Range. From river bottoms through sagebrush hills to forested mountains, the drive offers the opportunity to visit portions of the Lewis and Clark National Historic Trail and the Continental Divide National Scenic Trail.
 
Directions
From Idaho Falls, follow Interstate 15 north 24 miles to Sage Junction (Exit 143). Then follow State Highway 33 west 12 miles to Mud Lake and State Highway 28. Follow State Highway 28 northwest 105 miles to Tendoy. From Salmon, Idaho, travel south 20 miles on State Highway 28 to Tendoy, and turn left onto the byway. The byway roads are also known as Warm Spring Wood Road and Agency Creek Road.
 
Visitor Activities
Historic site, interpretation, wildlife viewing, birdwatching, hiking, mountain biking, big-game hunting, snowmobiling, cross-country skiing, motorboating, scenic drives, and swimming.
 
Special Features
Sweeping views of mountain ranges and river valleys are typical along the Continental Divide. The byway includes historic sites, such as Lemhi Pass (elevation 7,373 feet) where Lewis and Clark crossed the Continental Divide, and access to Sharkey Hot Springs, a developed hot spring complex offering two soaking pools. Wildlife includes deer, elk, moose, bears, pronghorn antelope, and many bird species.
 
Permits, Fees, Limitations
The road is usually snow-covered from November–early June. During those months, the roadway is groomed for snowmobile use only.
 
Accessibility
Accessible vault toilets are located adjacent to the Tendoy store, the byway welcome site (3.5 miles north on Warm Springs Wood Road), and the Agency Creek Recreation Site, approximately 5 miles east on Agency Creek Road from Tendoy. Sharkey Hot Springs offers accessible vault toilets and two accessible soaking pools (1.5 miles east on Warm Springs Wood Road). Accessible vault toilets at Lemhi Pass are scheduled for construction in 2003.
 
Camping and Lodging
There are no campgrounds along the byway itself; primitive camping is available at the Agency Creek Recreation Site. Lodging is available in Salmon.
 
Food and Supplies
The Tendoy Store offers gas, some food items, byway information and interpretive services, and a post office. Portable toilets are located adjacent to the store.
 
First Aid
Travelers must possess at least basic first aid skills; assistance is some distance away. Ambulances are available in Salmon and Leadore (25 miles south of Tendoy via State Highway 28). A hospital is located in Salmon. There is very limited mobile phone service along the byway.
 
Additional Information
The gravel road is a single lane, with occasional pullouts for passing. From Salmon, the trip takes at least half a day. Vehicle access is best in the summer, as snow blocks the roads during the winter months. Roads are very rough and at least one inflated spare tire is a must. Brochures and information are available at the Tendoy Store and from the BLM/U.S. Forest Service joint office in Salmon. The byway is a cooperative effort of the Salmon Field Office, BLM, and the Salmon-Challis National Forest. The route has been designated a state Scenic Byway by the State of Idaho.

The Lewis and Clark Back Country Byway crosses Lemhi Pass, homeland of the famous Native American guide Sacajawea. The mountains represented a formidable barrier to the explorers’ Corps of Discovery in their 1805 quest to find the “Northwest Passage” to the Pacific Ocean.
