## Other summits with same name

The state of Colorado actually has four other Grizzly Peaks and one Grizzly Mountain on record. The Grizzly Peak in Chaffee County, which sits in the Sawatch Range, is the tallest of these. The Summit County Grizzly Peak is fourth-tallest of the mountains, and is thus also referred to as "Grizzly Peak D":
| Rank | Mountain | Elevation | Range |
| 54 | Grizzly Peak | 13,995 ft (4,266 m) | Sawatch Range |
| 130 | Grizzly Peak | 13,738 ft (4,187 m) | San Juan Mountains |
| 142 | Grizzly Mountain | 13,708 ft (4,178 m) | Sawatch Range |
| 145 | Grizzly Peak | 13,700 ft (4,176 m) | San Juan Mountains |
| 302 | Grizzly Peak | 13,433 feet (4,094 m) | Front Range |

## Hiking

The trail to Grizzly Peak, which allows hikers to reach the summit of the mountain by foot, is accessible immediately off of a parking lot at Loveland Pass on U.S. Highway 6. The trailhead begins above the treeline at about 12,000 feet (3,700 m) and rises to the peak, but reaching the summit does not necessarily require the use of extra mountain climbing equipment such as ropes. Visitors can also reach Mount Sniktau, a smaller peak, from the same point along Loveland Pass.
From the summit, hikers can see Loveland Pass below them, plus views of nearby Chihuahua Lake and the Arapahoe Basin ski trails.
