Eastern Idaho Byways
Fort Henry - See the first white settlement marked by the Fort Henry Monument, from which this byway gets its name. A new monument now replaces the old one at the original site. The old monument relocated in an adjoining field can be viewed from the original site. This route trails along BLM land, desert and mountain ranges; where herds of deer and elk, as well as Sharp Tail and Sage Grouse can be seen as you journey along the Red Road...
Lewis and Clark | Printable Booklet - Two hundred years ago, Meriwether Lewis and William Clark stood high on a ridge-line that divides continental waters, and began the discovery of the Pacific Northwest. Stands of fir and oine trees, high-mountain meadows and rolling, jade-colored hills look much the same today as when the famous explorers journeyed to the crest of Lemhi Pass in 1805...
Lost Gold - This loop travels southwest along the desert-lava rolling hill terrain where cattle and wild game peacefully share spring and fall months grazing. This early-day Gold Trail closely follows Beaver Creek towards the Montana gold mines. At Spencer the Gold Trail of yesterday becomes the Opal Trails of today and passes several high grade Opal Shops within the original Wood Livestock town site. Leaving Spencer, the trail heads east to Idmon. This early day Nez Perce Trail has spurs off of its main roadway to private opal mines, Caribou-Targhee Forest fishing and primitive camping areas, and an old cemetery, connecting again to the Fort Henry Historic Byway at the old Idmon town site...
Mesa Falls - The Mesa Falls Scenic Byway begins where the Teton Scenic Byway reaches its northern end in Ashton, at the junction of U.S. 20 and Idaho 47. From there, the route travels through the town of Warm River toward its main attractions: the Upper and Lower Mesa Falls. The Mesa Falls are the only major falls in Idaho not used for irrigation or hydroelectric projects, and as such maintain a look and feel of nature undisturbed. At 110 feet and 85 feet, respectively, the Upper and Lower Mesa Falls offer equally spectacular views in a beautiful forest setting...
Oregon Trail-Bear Lake - Bear Lake straddles the Idaho-Utah border and boasts sandy beaches, great water sports, fishing, boating, and the famous Bear Lake State Park. This byway follows Bear Lake north on U.S. 89 to Montpelier, then north on U.S. 30, where you leave the Cache National Forest and enter the Caribou National Forest...
Pioneer - On this route, travelers can retrace some steps of Idaho’s early pioneers and follow the historic path taken by early-day Yellowstone Park visitors. From Franklin, Idaho’s oldest settlement, this byway heads north to Soda Springs and on to the Wyoming border. This route offers the shortest distance and time between Salt Lake City and Yellowstone Park...
Sacajawea - Sacajawea, an "Agaidika" Shoshone woman born around 1788, is known around the world as a trusted and valuable member of the famed Lewis and Clark Corps of Discovery. A lesser-known fact, however, is her historical tie to Idaho's Lemhi Valley where she was born and raised until the age of twelve. Captured by the Arikira Indians and forced to live among them in the Mandan Villages of North Dakota, Sacajawea would not see her home again until becoming part of the Corps of Discovery in 1805. It was during this expedition that she would help Lewis and Clark find the Salmon River and revisit her people...
Teton - The jagged teeth of the Teton Mountain Range are actually in Wyoming, but Idahoans prefer “the quiet side” on the western slopes, along the Teton Scenic Byway. At nearly 10 million years young, the Tetons are the newest mountains in the Rockies. In fact, they continue to grow today at the snail-like pace of about an inch every hundred years. In fact, the largest peak on the range, Grand Teton, now stands at 13,772 feet...
