The Thumb Open Space is named for the thumb-like rock outcrop on the south side of the property. For decades this property was a popular, but privately owned, hiking and climbing destination. The first known climber of the Thumb was the legendary Tom Hornbein, who began frequenting the area in the late 1940s. The Thumb Open Space features were later used by professional climber Tommy Caldwell as a training ground. The property now offers nearly 50 routes from 5.0 to 5.13, as well as high-quality bouldering.
In June 2022 the city of Estes Park officially opened this area to the public. There are 65 acres. The area is also known for its great hiking, trail running and dog walking. You cannot miss the spectacular views of Longs Peak, Mount Meeker, and Twin Sisters. You don't have to walk far up the trail for the views.
The Thumb Open Space is open for wildlife and public enjoyment. The public access trailhead can be reached by traveling west one mile on Peak View Drive from the intersection of Peak View Drive and Colorado Highway 7.
