On the outskirts of Canon City, where the pavement gives way to dusty roads and the skyline broadens into Colorado’s wild hinterlands, Four Mile Creek Bouldering offers a real frontier experience. This expanse of Dakota sandstone sits just off the approach to Shelf Road, stretching in every direction beneath the wide western sky. Here, boulders pepper the landscape among hardy tufts of grass, patches of cactus, and the occasional wary steer, providing the perfect backdrop for a day of gritty, no-nonsense sending.

What makes Four Mile Creek truly distinct is its genuine, untamed energy. The stone you’ll find here runs the gamut — from bullet-hard patinas that inspire confidence under your fingertips to crumbly, chossy faces that demand caution and respect. Classic lowballs and daring highballs await those keen to test their limits, and because much of this area remains undocumented, there’s a heady sense of exploration in the air. You won’t find crowds or polished circuits; instead, you step into the unknown, carving out your own lines among the plunging washes and broad ridges. For those with a pioneering spirit, the potential for new or rediscovered problems seems almost endless.

Oil Well Flats and Dakota Dam mark the two main concentrations of boulders, but smaller clusters dot the arroyos and hillsides for miles. Oil Well Flats, especially, is a worthy day-trip, offering a wealth of boulders within clear sight of posted signage. The Dakota Dam area appears early on your drive, easily identified by a rusted old pipe perched above a dilapidated retaining wall beneath a congregation of giant stones. This is not just a bouldering destination, it’s a choose-your-own-adventure—each visit feels fresh, unfiltered, and just a little bit wild.

Of the existing climbs that have entered local lore, "The Prize (V4)" stands out as a must-try, earning high marks for movement and setting alike. Yet, grades here are as subjective as the day is long; what feels like V4 to one climber may feel a grade harder or softer to the next. Most of the landings are packable, and while some of the boulders demand spotters and multiple pads, the variety ensures there’s something for every style and ambition.

Conditions tend toward the favorable, particularly in fall and winter — the southerly exposure welcomes the sun and keeps the area climbable while other domains battle freeze-thaw or persistent snow. Yet, climbers must heed the sandstone's vulnerability: after rain or snowmelt, routes become friable, easily damaged, and sometimes outright closed to protect the stone (especially at Oil Well Flats). Best practice is to approach with patience and always prioritize preservation over tick marks. Hazards are not to be underestimated in this raw environment. Beyond sketchy rock, a roster of classic high-plains dangers awaits: rattlesnakes, ticks, cactus needles, mountain lions, stray shards of glass, and occasionally difficult four-wheel tracks. Stay alert, give livestock a wide berth, and respect private land boundaries. The nearby Dinosaur Flats Shooting Range is a loud reminder to be aware of your position. Even so, the sense of openness and freedom here reminds many why they fell in love with climbing in the first place.

After a full day, stories are best traded over coffee or a meal at local favorite Cafe Belay — a low-key spot where the climbing community often gathers to swap beta and plan the next outing. Four Mile Creek Bouldering is not a polished destination — it’s rough around the edges, full of surprises, as much about the adventure as the ascent. Those who come prepared and stay humble will find plenty to challenge and inspire.
