What Makes Black Bear Pass the Ultimate Off-Road Test?
Black Bear Pass (F.S. Road 648) isn’t just another trail—it’s a rite of passage. Winding its way from Red Mountain Pass to the heart of Telluride, Colorado, this high-altitude route cuts across the San Juan Mountains with hair-raising switchbacks, unforgiving ledges, and views that rival any national park.
Every year, off-roaders across the country flock to Black Bear when it opens in late July. But this isn't a trail for beginners. Its narrow shelf roads, thousand-foot drop-offs, and blind turns have earned it the nickname "Colorado’s Most Dangerous Trail."
For those who brave it? The reward is unparalleled: panoramic mountain views, a front-row pass to Bridal Veil Falls, and the sweet satisfaction of conquering a true Colorado legend.

Must-Have Gear Before You Drop In
RSG Offroad doesn’t just talk gear—we test it on trails like Black Bear. Here’s what we recommend before committing to that first descent:
🔧 Critical Trail Equipment:
-
Trail-Rated Tires
-
High-grip, low-PSI-ready tires are non-negotiable. Sidewall damage is common on rocky shelves.
-
-
Functional Brakes
-
Brake fade can turn deadly on steep, wet descents. Fresh pads, bled lines, and no funny business.
-
-
Locking Differentials
-
For added traction and control during slow-speed maneuvers over loose terrain.
-
-
Rock Sliders & Skid Plates
-
If you love your oil pan or frame rails, protect them. Expect underbody scrapes without armor.
-
-
Air System
-
Deflate tires before the climb and re-air once back on pavement. Portable air compressors are a game-changer.

Pro Tips for Surviving the Trail
“No shame in spotting. Lots of pride in surviving.”
— The RSG Offroad Crew
This trail is legendary for a reason. Here’s what else you need to know:
🌦️ Weather Moves Fast
Afternoon storms roll in like clockwork, turning dry dirt into slick mud or sudden rockslides. Start early.
👀 Blind Switchbacks
Use a spotter. Even if you're experienced, visibility is limited and there's no room for error.
⛓️ Bypass Culture Doesn’t Apply
There are no easy outs. Once you commit to Black Bear, you’re committed. Make sure your crew and vehicle are ready.
📸 Take It In (Safely)
Pull over only where it’s safe to stop. And don’t forget to grab a shot at Bridal Veil Falls—Colorado’s highest waterfall.
