Trail Information


Hall Valley is a quick, relatively easy, scenic 4x4 trail that is close to Denver, Colorado. It leads you through aspen, pine, and finally into an open basin where you can explore the old structures of the Missouri Mine by foot. There are other four-wheel drive trails nearby such as Red Cone, Webster, and Beaver Lakes along with the Gibson Lake and Whale Peak hiking trails. Hall Valley is named after Colonel William Jairus Hall, a local mine owner.

Recent snow storms have blanketed the trail creating dangerous driving conditions and rendering the trail impassable.

Trail was open and clear. Head all the way down to the end to get a view of the Whale Mine. I think it was used to mine Radium. There is some cool signage that makes for some cool pictures.

Overall great little trail. We camped and hiked up to Gibson lake. Pretty decent little water crossing just past the second waypoint but no problem at all for any truck/off road capable suv. Agree with the last review the road gets pretty rough/rocky quickly and I was shocked to see a few crossovers (rav4, crv) and even a Corolla…? My stock JKUR with KM2s @ 20 psi was fine but would not attempt this in a “cross over” with street tires…

Drove to the gate at 11500 feet, which is the end of the FS Trail. You can see a couple modern buildings of what appears to be an active mine just past the gate. No snow on the trail, but plenty around near the top. See the photos taken at the gate entrance. Lots of people camping all along the trail, but the two official FS campgrounds were closed. River was running very full and quickly, buts its generally no more than a couple feet deep at most. Keep the little ones away, for sure.

Ran this trail yesterday as part of the hike to Whale Peak, no snow yet. Nice little trail that leads to a mining area, although you can’t get too close to the mine as there’s a gate blocking the area due to high radiation. Okay views, seems like it’s really just used to get you to camping/hiking. I’d probably give this trail closer to a 3 rating just due to how rocky it is. No problems in a lifted 4Runner on 33s at 18psi, but I’d be worried about a puncture/sidewall blowout in a vehicle with a smaller profile tire.
