Grand Lake

Colorado's largest and deepest natural lake, wrapped by Rocky Mountain National Park's quiet west side.

About Grand Lake

Grand Lake is both a lake and a small boardwalk town in Grand County, sitting at about 8,370 feet at the western entrance to Rocky Mountain National Park. The park surrounds the town and lake on three sides, and Trail Ridge Road climbs away just north of town.

The lake itself is the largest natural body of water in Colorado and its deepest natural lake, reaching about 389 feet. It connects directly to Shadow Mountain Lake, and together with Lake Granby to the south they form the Three Lakes area at the headwaters of the Colorado River.

Compared with Estes Park, the west side feels slower and wilder. You get calm-water reflections, wooden docks and boathouses, moose in the Kawuneeche Valley and easy access to East Inlet and Adams Falls, all within a few minutes of the town's boardwalk.

Colorado's largest natural lake, sitting at the headwaters of the Colorado River on the west side of Rocky Mountain National Park, with a boardwalk-lined historic downtown right on the water. Ice breaking up in spring creates a genuinely striking two-tone effect across the lake's surface — open water alongside still-frozen sections — worth watching for specifically during the shoulder-season thaw.

History

The lake formed during the Pinedale glaciation, when a glacier's terminal moraine dammed the valley. The Ute called it Spirit Lake, believing the cold water was home to the souls of the departed.

The town grew in the late 1870s and early 1880s as a supply point for mining camps such as Lulu City, Teller City and Gaskill, served as the Grand County seat from 1882 to 1888, then turned to tourism. Since 1937 the lake has been part of the Colorado-Big Thompson Project, which sends West Slope water under the park and the Continental Divide through the Alva B. Adams Tunnel. Grand Lake incorporated as a town in 1944, and the 2020 East Troublesome Fire burned to the edge of town.

Photographing Grand Lake

Best light: Sunrise from the town side and west shore lights the peaks of the park to the east and north, and early morning is when the lake is most likely to be glassy. Mid to late September brings gold aspens on the surrounding slopes, and winter turns the lake into a frozen white plain.

Shots to look for

Glassy morning reflections of the peaks off the public beach and boardwalk area in town, 16-35mm
Wooden docks and boathouses leading into the lake, low angle with a long exposure to smooth ripples
Adams Falls on the East Inlet Trail, a short walk from the trailhead, with a slow shutter
Moose in the willows of the Kawuneeche Valley north of town at dawn, 100-400mm from a safe distance
Sailboats on the lake under summer storm clouds in the afternoon

Photo tips

Morning wind is usually calmer; reflections often disappear by mid-morning
Moose are common on the west side; stay well back and never get between a cow and calf
The East Inlet trailhead lot fills on summer weekends; arrive early
Burn scars from the 2020 fire are visible in places; they can add mood to a frame or be something to compose around
Bring a polarizer to control glare and see into the clear shallows along shore

Know before you go

Entering Rocky Mountain National Park requires a park pass, and the park has used seasonal timed-entry reservations; check nps.gov/romo for current rules
Trail Ridge Road over to Estes Park closes seasonally, typically from fall into late spring
The lake is very cold year-round even in midsummer
