This is such an awesome drive. A solid 3 hours from Denver. No service as soon as you get to the dirt part of the road, so its best to have your whole crew riding behind you in a line. A little anxiety when it comes to finding a spot, everyone is right when they say, have someone get there thursday to get a choice spot. But few people know if you keep driving up the canyon, there are more public lands spots you can claim as your site. 

Being there isnt a whole lot to choose from after the place fills up, we had some people literally show up Saturday on Memorial Day weekend, and camp right on top of our campsite, which was pretty annoying, but thats the price you pay at free public land dispersed camping. 

Awesome drive up the canyon to the small mining town of "Victor" which is just an awesome time capsule town, i highly recomend swooping through.
