Highlight: Stony Pass

Situated in the San Juan Mountains near Silverton, Colorado, Stony Pass crosses the Continental Divide and is one of the longest uninterrupted off-road climbs in the entire state. It used to be a major supply route into Silverton from the east until 1882 when the Durango to Silverton Narrow Gauge Railroad made it obsolete. It became just a road utilized for mining before it was abandoned. The road was reopened as a four-wheel drive route by the US Forest Service in the 1950s. Optional side trips are available that allow you travel up to the historic Buffalo Boy Tram Station and beyond up to 13,000' in elevation. Wildflowers, alpine views, and mining history make this a trip worth taking.

Stony Pass can be used as a route from Silverton over to Lake City, Creede, Kite Lake, or simply as an out and back. The route is not technical, but there are several spots that are steep and rocky. The roads are either maintained and unmaintained dirt and cobble depending on which part of the trail you are on. The optional side trip up to the Buffalo Boy Mine would pose the most difficult issue in wet weather where the road is steep and comprised of dirt making it very slippery. In the spring, the east of the Pass is known to have several deep creek crossings which should be traversed with care. Access, depending on the winter snowfall, is usually late May through October. You can couple this trail with either Engineers Pass or Cinnamon Pass to make for a multi-day overland trip.

His want and desire to find passable trails and new nooks and crannies of the Great American West to explore were his reasons behind starting On any given weekend you can find Todd on some obscure 4x4 trail or using his legs to hike to an alpine lake.


Questions & Answers (3)

Q: Hi Todd--we're gearing up for trip this week. Any beta on the timber hill section? We'll be in a stock 4wd 2015 Grand Cherokee. I'm novice/light intermediate w jeeping . . . Grew up in Ouray so I've definitely done some. Any advice appreciated.
–Chris Wood (09/04/2017)
A: A stock 4x4 grand cherokee will make it up Timber Hill just fine. There are only a couple a really rough spots (nothing like Imogene) that need to be taken slowly otherwise Stony is not very difficult.
–L wetherill (02/10/2018)
A: Chris, I am not sure I understand your question. If you mean going up beyond the Buffalo Boy Mine, do not do it when wet. As with all off-road adventures, never go alone and never be afraid to turn around when you are beyond your comfort level. The most difficult part of the trail would be that hill beyond Buffalo Boy Mine when wet, or at waypoint 15 where it was considerably more rocky than the rest of the trail.
–Todd (09/05/2017)
Q: Looking to take my family over from Silverton side to Creede in early September. 2015 Jeep Grand Cherokee 4X4. Any extra advice? Best spot to camp for a couple nights and explore from?
–Chris Wood (08/20/2017)
A: Hey, Chris sounds like you will have a fun time! Right around Waypoint 13, there were some really good camp spots, but my personal favorite was at Waypoint 16.
–Todd (08/20/2017)
Q: Do you think that a 4wd Ford F250 can make the trail without problems? Looking to go from 149 all the way to Silverton
–Christopher (06/10/2017)
A: Potentially if you take the turn left at waypoint 3 to explore the mines you may need a couple multipoint turns. At waypoint 15 the trail got fairly narrow and rocky, and there are a few spots in the area you will have to navigate in between trees while the trail meandered through them. For reference, the guide was written in an 80 series Landcruiser which is 189.8 inches long and had no problems.

I drove the full length of Stony Pass from Silverton to Hwy 149 in my 1988 Isuzu Trooper. The road is open and in good condition. There are a few wet spots but overall dry. From Silverton to Kite Lake intersection (Waypoint 14) I was with a group from Isuzu Wheelers (Facebook group). Together, we drove the spur road up to Buffalo Boy Mine, then back down and over the pass, and up-and-back to Kite Lake. After completing Kite Lake, I proceeded east to Creede and the others went back to Silverton. This is a fantastic connector road with lots of history/mining artifacts and wonderful mountain scenery.

I love Stony Pass for the journey. At 40 some miles, this is just a great adventure. We left Silverton late and camped along the way. The camping next to the Rio Grande to me is one of those iconic moments you just have to experience.
