BackBone Grande Visual Tour (3) - Custer to Hill City (miles 135-163 & alternative)

If tomorrow all the things were gone, I'd worked for all my life
And I had to start again, with just my children and my wife
I'd thank my lucky starts, to be living here today
Cause the flag still stands for freedom, and they can't take that away.

And I'm proud to be an American, where at least I know I'm free
And I won't forget the men who died, who gave that right to me
And I'll gladly stand up next to you, and defend her still today
Cause there aint no doubt I love this land, God Bless The USA.

The BackBone Grande is my 420+ mile backroad bikepacking route across the State of South Dakota along the spine of the Black Hills and through the surrounding prairie. Inspired by my experience riding the Great Divide Mountain Bike Route, I designed it to create that type of experience here in my back yard. Tracking rough roads that showcase the best of our scenery, history, culture, and wildlife, the BackBone Grande is a great ride on its own and as a shakedown for the GDMBR.  For a collection of my stories all about it, go the BackBone Grande Page.

For those more visual learners, I've selected images along the route from various scouting trips, the first through-ride, and other rides. Here is my third installment of the BackBone Grande Visual Tour, from the town of Custer to the town of Hill City, both the Main Route (miles 135-163) and the Mt. Rushmore Alternative Route (41 miles). 

The BackBone Grande is a rough road bikepacking route across the State of South Dakota along the spine of the Black Hills. It generally follows dirt/lightly graveled USFS roads in Black Hills National Forest, barely discernible BLM roads in Buffalo Gap National Grassland, and county gravel roads out on the surrounding prairie.

The BackBone Grande occasionally uses pavement as a connector, where necessary, and even passes through a few small towns. At its core, however, it is a backcountry road route, like its inspiration, the Great Divide Mountain Bike Route.

So, the BackBone Grande follows the Mickelson Trail out of Custer, climbs up Spring Creek Road (USFS Secondary Road 305), turns onto highly variable Reno Gulch Road (USFS Secondary Road 303) past a Marmot Motel to Coad Hill for Harney Peak views, and then rapidly drops back to the Mickelson Trail for the final few miles into Hill City. Every bit of this stretch oozes the BackBone Grande vibe.

All that being said, people from the world over flock to the Black Hills for more conventional tourist experiences. Many drive paved highways that were actually purpose-built for tourism, including Needles Highway and Iron Mountain Road, aka Pigtail Highway. Being much busier, more developed, and overall more civilized than the roads on the Main Route, these roads provide a significantly different cycling experience than the BackBone Grande.

Nonetheless, in response to feedback from out-of-state bikepackers, earlier this year I added the Mt. Rushmore Alternative for the BackBone Grande stretch between Custer and Hill City. This alternative route climbs paved Sylvan Lake Road (State Highway 89) to Sylvan Lake and then follows paved Needles Highway (State Highway 87) up, through, and down the Needles. To inject a bit of backcountry, the route turns onto Camp Remington Road (USFS Secondary Road 345) and directly onto Iron Creek Trail for a bit of mellow single track with multiple creek crossings. Then it's back to paved Iron Mountain Road, aka Pigtail Highway (U.S. Highway 16A) and up a pitched 2 mile climb on U.S. Highway 244 to Mt. Rushmore National Memorial. West of Mt. Rushmore, the route turns off U.S. Highway 244 onto USFS Low Standard Road 356 to connect with paved Old Hill City Road for the short jog into Hill City.

So, the Mt. Rushmore Alternative is a mostly paved highlight reel of conventional tourist sights, with a smattering of short, rough patches as a reminder that it's still the BackBone Grande.

Choose, you must.

rough Secondary to solid Primary to eventually some pavement.

BackBone Grande Visual Tour (2) - Buffalo Gap to Custer (miles 95-135)

Welcome to the jungle
We take it day by day
If you want it, you're gonna bleed
But it's the price you pay.

Here is my second installment of the BackBone Grande Visual Tour, from the town of Buffalo Gap to the town of Custer (miles 95-135). For the first post of this series, go to Nebraska Border to Buffalo Gap (miles 0-95).


Although but 40 miles, this stretch of the BackBone Grande is stuffed with striking visuals, as the route meanders on ancient migratory paths out of vast grasslands to wintering grounds nestled in the protective terrain and vegetation of the Black Hills. 

Gradually climbing through Buffalo Gap, the route enters Wind Cave National Park and then Custer State Park, where herds of buffalo roam free, along with deer, antelope, wild burro, and constantly chattering prairie dogs. The forest thickens, but does not fully develop until after topping infamous Trail #1, the signature rocky, loose, steep, brutal climb of the BackBone Grande.

Awaiting ahead lies the splendor of French Creek Horse Camp, a delightful creekside single track connector, a ridge line spin overseeing the Cathedral Spires, and a final drop into the town of Custer.

Welcome to the Black Hills of South Dakota.
