Access the new Raspberry Ridge / Blackjack trails by dropping down the Homestead trail and picking up Raspberry Ridge as it peels off to the left.
Raspberry ridge is a technical climb complete with chunky rock sections and steep slickrock that basically functions as an access trail to Blackjack. Be warned: if you can't ride Raspberry Ridge, you are going to have some major issues with Blackjack.
Blackjack is advertised as a technical, black diamond freeride trail. Don't believe it because all of the other trails at Buffalo Creek are so buttery smooth? Believe it.
Blackjack is a gnarly freeride area that is tough in the easiest of spots and downright extreme in the most technical. Major trail features are labeled with ratings going up to double black diamond. Major features include steep chutes, drops up to five feet, chunky rock gardens, and steep slickrock rolls. Some sections have blue or green bypasses (although take note: blue and green by Blackjack standards is black by other standards), but many do not. Always ride in control and be sure to scout out the serious features before you ride them.
