The route will start and finish in downtown Boise’s north end in historic Hyde Park at 13th and Eastman.  There will be a neutral rollout heading south through town and to the Greenbelt, which parallels the Boise River.  The Greenbelt is narrow and will have bikers and runners so the pace needs to be casual as you head east – consider it social hour.  It’s a beautiful river and the Greenbelt meanders through several parks as you head toward Lucky Peak Reservoir.  At the Lucky Peak reservoir continue east up two track Lydle Gulch to Bonneville Point and on to Blacks Creek.

The route continues on Blacks Creek for a few miles on pavement and then transitions to a dirt road with multiple steep climbs and descends along the South Fork of the Boise River.  After topping out, look for the Y-Stop General Store to your left, or head a few miles into Prairie on the route to the Mercantile for good grub.

From Prairie there are multiple climbs and a fast descent through the woods on Forest Service roads to Anderson Ranch Reservoir and the town of Pine.  Pine has a restaurant and a mini mart for resupply.  Continue on to Featherville along the S. Fork of the Boise River.  Multiple camping and hot spring opportunities are available.  Featherville has a saloon, general store and a restaurant – great food, drink and people in this out of the way micro-town.

From Featherville the route goes to Ketchum on rolling dirt Forest Service roads paralleling the river for most of the way. Due to wash outs from floods, there are several boulder fields that must be navigated along with a narrow trail as you roll into Smokey Bar. Then a long climb up to Dollarhide Summit in the central Smoky Mountains with majestic views of the vast Idaho wilderness.  A long rocky switchback descent through the recent fire burned forest takes you to the town of Ketchum.  Excellent camping on the river and several hot springs are in this area.  Wildlife is abundant and black bears forage between the road and the river.  Be bear aware!

Ketchum is a great mountain town nestled in the Wood River Valley with all services and a bike shop close to the route.  The route goes north on exceptional single track before you access the scenic two-track Harriman Trail, named after Averill Harriman, the man who conceived and built Sun Valley.  There’s plenty of camping in this area with imposing views to the east of the Boulder and Pioneer Mountains.   The Harriman Trail spits you out at the base of Galena Summit, where you then grind/hike up to the top of this high mountain pass via Titus Lake on single track.  Big panoramic views are to the north of the glacially carved Sawtooth Mountains and Sawtooth Valley.

The route descends on the Idaho Centennial Trail (primitive dirt road) to the valley floor where mountain streams come together to form the headwaters of the Salmon River, also known as “The River of No Return”.   The route follows the Centennial Trail and the views of the valley are immense.   Smiley Creek Lodge is a short distance off route for resupply.   The route continues north on the Centennial Trail and pops out to the highway for a brief paved section and then to Fisher Creek for singletrack through the forest and a burned moonscape. A big uphill is followed by a screaming fast and dangerously smooth downhill and back to the valley, with terrific views of the jagged Sawtooth range to the west.  Back on Highway 75 you double-back and ride more Centennial Trail along the edge of the Sawtooth wilderness.

The route takes you to pristine Redfish Lake, named for the brilliant sockeye salmon that once returned from the ocean in such massive quantities that the lake shimmered red during spawning season.  These fish are now on the endangered species list.  This striking mountain landscape features a chaos of crags and razorback ridges.  At Redfish there is a small store, restaurant, rustic lodge, beach and camping available.

The route takes you back to the highway via sweet Fishhook Creek and on to the mountain town of Stanley where services are available.  Stanley is consistently one of the coldest spots in Idaho and frost can occur any time of year.  Be prepared for cold night time conditions and unpredictable weather.  The route heads north to Lower Stanley and then toward  Stanley Lake via Nip and Tuck Road and the base of McGowen Peak and on to Elk Meadow for some excellent singletrack after a climb up a primitive road.  Descend a rocky section through a lodgepole forest and then drop into a massive, boggy meadow.  Ride through the evergreens on singletrack and eventually a fire road back to Highway 21.

After a short stint on the highway you follow the rolling Centennial Trail along Marsh Creek and the Cape Horn region, featuring a landscape mosaic of riparian, meadow, sagebrush and conifer vegetation.  Marsh Creek supports waterbirds and there is a high density of Sandhill Cranes.  There is another stint on the highway before grinding up to Cape Horn summit and on to Bear Valley, which is a series of meadows surrounded by timbered mountains.  The road skirts the boundary of the Frank Church –River of No Return Wilderness.  Deer and bear are the most common big game animals here, but one could see elk, moose, and wolves.  Many camping opportunities exist through this area.

The route continues on forest service roads to Deadwood Reservoir – expect washboard conditions.  The road continues onto Scott Mountain Rd. and climbs a narrow and steep road to the summit for considerable views of the Sawtooth range to the northeast.  Scott Mountain lords over Garden Valley to the south at an elevation of just over 8,000 feet.  A long and fast descent takes you to the scenic highway, heading east next to the Payette River toward Garden Valley, which is a mile off route for resupply.  Enjoy a few old forgotten roads, affectionately referred to as Mordor, as you head toward the charming semi-ghost town of Placerville, where one tiny convenience store may or may not be open.

Out of Placerville, the road connects to the Harris Creek Road, which is a major connector through these hills.  From a high saddle the route goes to Boise Ridge Road, an unassuming backcountry road with crazy steep climbs winding from ridge to ridge.  You will see Shafer Butte and Moore’s Mountain off in the distance.  These landmarks comprise Bogus Basin and mark the final summit before descending towards Boise.  Before topping out, the route skirts around the mountain on single track through old-growth forest and lush meadows, eventually tying into Ridge Road.

Ridge Road is a rolling dirt road that sits above Boise across the top of the foothills with panoramic views of the city and the valley.  From Ridge Road begin the flight down singletrack that is long, fast and well groomed to the sagebrush-covered lower foothills.  Singletrack punches out a few miles above Boise onto Bogus Basin Road, which is followed back to Hyde Park at 13th and Eastman.  The ride ends here to much fanfare!
