Adopted Trails

CORE has adopted the following Trails:

Salida Ranger District

Grizzly Lake - FS 296

Grizzly Lake is a difficult rock crawling trail that takes you over one demanding challenge at the start to steal your attention, and then never gives that attention back till the trail run is over. This trail combines all aspects of rock crawling into less than 3 miles. With ledge climbs, water crossings, shelf roads, off camber leans, and tight squeezes between trees, the trail finally rewards you for your courage by providing epic Rocky Mountain views at its ending point. Bring your camera, bring your fishing rod, but most importantly, bring a well equipped vehicle as the trek to Grizzly Lake is certainly an adventurous one. 

Tincup Pass - FS 267

Cutting through two National Forests and crossing the Continental Divide at 12,154 feet, this off-road trail offers beautiful high alpine views while following the same route used by miners and prospectors searching for their fortunes in the late 1800's. This relatively easy route takes you from one historic mountain town, right into another. St. Elmo is a true ghost town that was built during the mining boom of the 1880's, while Tincup, originally called Virginia City, has been resurrected as a popular summer destination with many historic buildings still in use today.Hancock Lake - FS 295

Pomeroy Lakes - FS 297

If you enjoy mining history, alpine fishing and camping then this trail is a must do. You will gain a glimpse of the areas mining history as you begin the trail at the old townsite of Romley. You will then pass several arial tram towers that are still standing before you reach the Mary Murphy Mine area, which offers an opportunity to explore several of the old structures that are still standing. After the mine you will continue through meadows and heavy timber before you reach the parking area at an elevation of 12,109' with a view of Lower Pomeroy Lake. Upper Pomeroy Lake is about a mile hike farther up the basin along an old road and is situated below Pomeroy Mountain (13,151').

 Hancock Lake - FS 295

Alpine tundra, pristine lakes, epic fishing and high mountain valleys are just some of the rewards that await at the end of the Hancock Lake Trail. The trail begins at the old townsite of Hancock, Colorado and from there heads south into the Chalk Creek Pass Valley. You will traverse through conifer forests, willows and tundra on your way toward the parking area that sits at just over 11,600' of elevation. A short hike from the parking area brings Lower Hancock Lake into view, and a more focused hike will take you to Upper Hancock Lake that sits just a bit higher in the valley. Be sure to respect this pristine area and pack out everything you pack in.

Hancock Pass - FS 299/266

Situated near the famous ghost town of St. Elmo and within the San Isabel National Forest, this trail will lead you up and over Hancock Pass and the continental divide at an elevation of 12,140'. You will also travel through some of the most historic and beautiful country that Colorful Colorado has to offer. If alpine passes, turn of the century railroads, mining history, and ghost towns are what you are looking for, this entire area will not disappoint! It is a must do.


Leadville Ranger District 

Champion Mill - FS 110

South Halfmoon - FS 110J

Tucked between two goliath fourteeners, Mount Massive & Mount Elbert, here the views are jaw dropping. There are so many things to explore on this trail it could take an entire week.Halfmoon Creek is a favorite of many Trailsoffroad members. There is a mix of both easy and difficult terrain, a few water crossings and plenty of spots with fire rings for dispersed camping. It is common for the trailhead to be very congested with hikers attempting to summit Elbert and Massive, but as you cross the creeks you get the feeling you might be the only one out there.

Clohesy Lake - FS 381

The Clohesy Lake Trail is one of the few remaining roads that has access to the Collegiate Peaks Wilderness area. The trail follows the Lake Fork Valley and ends within walking distance of Clohesy Lake. Once a private lake that was the site of a fish hatchery in the late 1880s, it has now been returned to the Forest Service and is part of public land. The lake is situated in Lake Fork Valley between Mt. Missouri (14,075') and Mt. Huron(14,003'). The views are spectacular and the fishing is equally as impressive. This area also offers access to several popular hiking trails. Stay on the road at all times to avoid causing damage to the area, and to help us keep this trail open!

Lost Canyon - FS 398

Situated in the San Isabel National Forest, halfway between Leadville and Buena Vista, Lost Canyon is a fantastic day drive for any 4wd vehicle. Home to some great primitive camping, this off-road trail delivers some of the best overall views you can find in the area. You can observe multiple, 14,000+ foot peaks on this drive and also gaze down on several of the largest bodies of water in the area including Clear Creek Reservoir, Twin Lakes, Mt Elbert Forebay, and even Turquoise Lake. During the fall, this trail provides spectacular aspen viewing because of the plethora of Aspen all along the trail. If scenery really isn't your thing, try your luck at gold panning and hope to strike it rich in the popular Cache Creek.

Slide Lake - FS 145
