Blackjack is the newest trail in the Front Range, and also our first "freeride" style of trail. It was built over the past two years by a partnership with Front Range Mountain Bike Patrol, COMBA (an IMBA partner), volunteers, and the USFS South Platte Ranger district.

Use at your own risk!

The trail consists of 12 "features", which can range from extremely technical  
Slot Machine down
Steep hard start!
to loose but smooth singletrack, typical of the SPlatte area.

Between the features are fun slickrock playgrounds and the typical South Platte decomposed granite surfaces.

The split - more fun right.
Like Moab, except granite.... and almost 4,000  higher.
Moab-like playground.

Trail Description

After the climb up from Raspberry Ridge,  
R.R. and Blackjack intersection
Intersection and the start of Blackjack.
which has its own bit of fun singletrack and technical features, the trail drops from the top of the ridge at 8,140' down to Sandy Wash trail, a descent of almost -700'.

As with Raspberry Ridge, this is a technical trail with very technical features. One should definitely walk the feature before attempting to ride it.

Getting There

Accessed from the Raspberry Ridge trail off of Homestead. See the main Buffalo Creek page for detailed directions to reach both of those trails. NOT recommended for attempting to ride uphill from Sandy Wash. This is meant to be ridden downhill off of Raspberry Ridge.


The shortest possible (and more importantly, least gain) route to access Blackjack is probably from the Miller Gulch Trailhead. From the TH, ride the Miller Gulch trail (old road) to Charlie's Cutoff, then up the short bit on Homestead to Blackjack. To return, take a right at the bottom of Blackjack and go back up hill to either Charlie's Cutoff or continue uphill on Homestead, returning to Miller Gulch.

When to Bike

As on the main page for Buffalo Creek, this area can be brutally hot in the summer (start early!). Snowfall is usually light down in this area, so you can usually ride the entire area almost year round, barring heavy snowfalls.

That said, riding the granite slickrock and features when they are wet/icy/snowy is not recommended, as they are very steep.
