Donner Lake

Donner Lake is a glacial alpine lake on the eastern slope of the Sierra Nevada, just west of Truckee, California, and about 20 miles northwest of Lake Tahoe. Donner Lake Inn sits steps from its western shore — on Gregory Creek, one of the lake’s own tributaries — making it one of the closest places to stay to the water. The lake is the namesake of the Donner Party, the emigrant wagon train stranded here through the winter of 1846–47, and today it’s a quieter, less-crowded alternative to the Tahoe shoreline for swimming, boating, fishing, and hiking.

The lake at a glance

Donner Lake sits at 5,936 feet and runs roughly three miles long by about half a mile wide, covering around 1.3 square miles, with a maximum depth of about 238 feet measured by the California State Lands Commission. It was carved by glaciers during the last ice age — a terminal moraine at the eastern end forms a natural dam, and the modern water level is held by a small dam built in 1928. The lake is fed by Summit Creek, Gregory Creek, and mountain springs, and drains east through Donner Creek into the Truckee River, whose waters eventually reach Pyramid Lake in Nevada. The cold, clear water holds some of the largest lake trout (mackinaw) in California, along with rainbow and brown trout and kokanee salmon.

A short history: the Donner Party

The lake was originally called Truckee Lake. It was renamed for the Donner Party — a wagon company of roughly 87 pioneers led by George Donner and James Reed — who left Illinois in the spring of 1846 bound for California and were trapped by early, heavy snow near the lake’s eastern end that winter. About half the party died before relief reached them in 1847, and the survivors’ ordeal made the name lastingly famous. The eastern shore is now Donner Memorial State Park, established in 1928, where the Pioneer Monument stands on a pedestal 23 feet tall — said to mark the depth the snow reached that winter. Long before, the Washoe people used the lake and surrounding canyons for thousands of years; the green, well-watered ground near the lake’s outlet, now the state park, was a long-established gathering place.

Swimming, boating, and the shoreline

Yes, you can swim in Donner Lake. It warms enough for comfortable swimming from roughly July through early September and stays bracingly cold the rest of the year. West End Beach, a sandy public beach with a seasonal boat launch, is a four-minute walk from the inn. There’s also a public boat ramp on the north shore, run by the Truckee Donner Recreation & Park District, and the Donner Lake Marina rents kayaks, paddleboards, and canoes through the summer. A flat shoreline trail begins steps from the inn, and the Donner Lake Rim Trail and other area hikes climb the ridges above the water.

Getting there and orientation

Donner Lake is about three miles west of downtown Truckee, reached from Interstate 80 via the Donner Pass Road exit. It’s roughly a 20-mile drive — about half an hour — from the north shore of Lake Tahoe, close enough for a Tahoe day trip but with its own quieter character (see Donner Lake vs. Lake Tahoe for how the two compare). The inn sits on the west end of the lake, the closest residential shore to the water. The road along the north shore and past the inn follows the original Lincoln Highway — the first transcontinental highway, opened in 1913 — which climbs from the lake up to Donner Summit (more on that historic corridor). For a sweeping view of the whole lake with the Sierra crest behind it, the Donner Lake Overlook on old Highway 40 (Donner Pass Road), above the west end, is worth the short drive up.

The lake through the seasons

In summer the lake is the center of life here — swimming, paddling, boating, and fishing, with the warmest water in August. Fall brings quiet, cooler days and good fishing as the crowds thin and the aspens turn. Winter transforms the shoreline: the surrounding hills fill with snow, the quiet beaches make for serene walks and snowshoeing, and Donner Pass just above the lake is one of the snowiest places in the Sierra — the same geography that trapped the Donner Party. Spring runs high and cold, snowmelt feeding the creeks before the summer season begins again.

For guests of the inn

Because Donner Lake Inn sits right on the western shore, the lake is effectively the back yard: West End Beach and the shoreline trail are a short walk, the marina and boat ramp a few minutes away, and places to eat range from an ice cream shop directly across the street to a lakeside pub. The full guide to things to do around the lake covers the rest of the season’s activities. For how the inn compares with the other lodging around the lake — the lakefront condos, the historic lodge, vacation rentals, and camping — see where to stay at Donner Lake. The same Gregory Creek that feeds the lake runs past the inn’s hot tub, with its headwaters protected just upstream in Johnson Canyon.
