This is the old AES route. From Rock Springs take the paved frontage road and link up with Maggie Mine Rd. This turns to dirt about 5 miles from the start. Stay on this road until the top of Antelope Creek, then ride the BCT all the way back to Rock Springs. It's a 21 mile 'warm-up', then 29 miles of BCT goodness. Don't forget to stop for pie in Rock Springs!

Solid black diamond, the loose Rocky rutted out section can be pretty dangerous.

Nice trail for a self-shuttle ride in and out then continue to Hidden treasure and Bumble Bee trails. The trail is rated blue intermediate but watch out with the exposure sites and loose dirt on the edges will keep you on your toes for sure. Mostly flow with some sketchy switchbacks and decent altitude gain.

My favourite segment of the BCT, you really are in the middle of nowhere with very few (if any) people. Some exposure on parts of this trail but the scenery is just amazing. The trail beautifully meanders the contours of the canyon and below Sunset Point of the highway.

As a hike this is just along the road into (& out of) town. There is enough space off the road (to the side) to walk but it really isn’t much fun.
It’s ok if you’re riding it but again not much fun.

Fun section of BCT. Descent (Southbound) is a blast. Climb (Northbound) is a little bit of work, but mellow grades, non-technical, totally cleanable. Easy Blue.

Fun section of BCT. Southernmost 4 miles is a fun, flowy descent Southbound, and a straightforward, easy climb Northbound. The Northernmost 2 miles of this segment are not particularly exciting, but quite easy.

Also, if you're an out-of-state visitor, this section of the BCT is sort of a transition zone where the Saguaros appear/disappear depending on direction. South of here, Saguaros line the trail pretty much the whole way. North of this section, there are a couple of outliers along the Antelope Creek section, then they're gone. Still pretty desert, but a very different feel.

January 2022, great section. Southbound it's maybe a little bit easier than the section to the immediate North (Arrastri Creek.) Call it "Advanced Blue" (absolutely NOT double black...) Northbound would be tough- there's a 3/4 miles stretch near the Northern end that would have most riders walking a ways... I returned via the Maggie Mine Road, which was quick and easy.

January 2022, loved this stretch of BCT. I'd rate it blue-black. Northbound is more difficult to clean than Southbound. Trail was in great shape, seems well-maintained.

Great trail! But a warning: we rode here after some rain and while the trails were awesome condition and just damp, the roads getting there (Crown King, Antelope Creek) were a muddy mess. In our 2 wheel drive vehicle we almost got stuck multiple places. I’m sure the locals know this but a warning for fellow travelers!

I've been riding dirt for 40 years. This is not even close to a "blue" trail. Black or double black.

This rode more like a black rating. More loose rocks than usual. Tough segment

This is a tough climb. Sustained, somewhat rutted, and loose. It’s all rideable, just tough. Stopped for a few minutes midway in to curse and remove clothing.

December 2019, trail overgrown, blood and pinholes in jersey and shorts. First ride spent walking frequently. I've been dirt riding since 1971 though I'm not a great rider. This is a hard and dangerous trial. Blue is bullshit.

Trail starts out somewhat mellow and gradually becomes more gnarly as you get closer to Maggie mine road. Take the blue rating with a grain of salt, concequnces for crashing on most of this trail are pretty high

This section recently burned. Makes it feel noticeably hotter and less pleasant than other sections. More like hell. More technical than previous blue sections.

Great single track! A bit of exposure, and some technical little bits, but great practice. And the view is grand.
