Aspen Campground is an excellent place for campers looking to relax, hike, fish and enjoy the sounds of nature. The campground sits near Jefferson Creek, a few miles downriver of Jefferson Lake. The lake is one of the highest elevation lakes around, capping 10,685 feet elevation and bordered by steep 12,000 foot peaks Fishing in both the creek and lake offer promising catches of trout. Another noteworthy aspect of the campground is its access to the Colorado Trail.
The campground offers nearby access to two trails. Hiking, biking and horseback riding are excellent on the epic Colorado Trail, a 471-mile trail that stretches across Colorado from Denver to Durango. Also nearby is the West Jefferson Loop Trail, a foot path that goes up to the Continental Divide and loop for 11 miles.
Rainbow, brown, mackinaw and brook trout can be found swimming in the creek and lake. No-wake boating is allowed in the lake and a boat ramp is easily accessible.
Amenities include picnic tables, vault toilets, drinking water from a hand pump and a campfire ring. Parking aprons are gravel and can fit up to two vehicles.
It is difficult to access Jefferson Lake Recreation Area during the winter months. The roads to this site are not maintained for snow throughout the winter.
Aspen Campground, at 9,900 elevation, sits in a valley along Jefferson Creek at the base of Jefferson Hill. The single-loop campground is shaded by groves of aspen and mature spruce. Jefferson Lake, spanning about 182 acres, has deep, cold waters and freezes over in winter.
