Camp at the trailhead. In front of the tent you can see some Colorado craft beer we are trying out.
We took a road trip to Colorado. After two days of driving we got to Golden Colorado. The next day we had a half day rest there visiting the mountaineering museum, and a Nepalese restaurant. Then we drove over to the Grays & Torreys trailhead.
The trailhead was in a national forest reserve so you could 'dispersed' (or we would call it random) camp there. People obviously did this a lot, and a lot of them, because there were many level tent sized places devoid of underbrush next to fire rings. We chose one near our friends vehicle (the road is more for 4x4's than cars) and set up camp above 11,000 feet.
