The 8,344-foot (2,543 m) peak is located 8.1 miles (13.1 km) south by west (bearing 196°) of downtown Boulder, Colorado, United States.

The City has a policy that restricts public access to this part of its holdings, and there is no trail going to the summit.

[4] Near the top of the mountain is a large antenna field with two buildings overlooking the steep slope on the east.

The site is reached by a private dirt road that starts further south in Plainview (a small community with less than a dozen homes) and then climbs the steep southern flanks.

On the east flank of Eldorado Mountain is its largest cliff, Mickey Mouse Wall.

When viewed from the north, two buttresses at the top of the cliff look like a pair of mouse ears.

Within the Park is the Rattlesnake Gulch Trail that climbs about halfway up the north flank of Eldorado Mountain.

About twenty miles (32 km) to the west, this line continues through the Moffat Tunnel under the Continental Divide.

[6] Near Eldorado Mountain, the aqueduct is mostly hidden in tunnels, but in three short sections it emerges above ground as a large pipeline.

After being abandoned by the railroad, the grade was used by the public as an access route to the west side of the canyon.

The grade continued to be the only such access until 1927 when the present road at the bottom of the canyon was built.
