Grays Peak is the tenth-highest summit of the Rocky Mountains of North America and the U.S. state of Colorado.

Grays Peak is located in Arapahoe National Forest, 3.9 miles (6.2 km) southeast by east (bearing 122°) of Loveland Pass on the Continental Divide between Clear Creek and Summit counties.

The trail, well-marked and well-trodden, begins by following the gulch for a slow rise in elevation, before hitting the steeper slopes.

Wildflowers that bloom in the tundra area on the Continental Divide of the Americas include moss campion (Silene acaulis), alpine forget-me-not (Myosotis alpestris), sky pilot (Polemonium viscosum), sea pink, old-man-of-the-mountain (Rydbergia grandiflora), and mountain gentian (Gentiana).

Below the tree-line, the blooms of monkshood or wolfsbane, blue columbine, fireweed, and paintbrush (Castilleja) can be found.
