Located at the northern edge of the Green Mountain National Forest in Washington County, the summit of Mount Ellen is in the northwest corner of Warren but the mountain extends into Fayston to the north and Lincoln to the west.

Together with Lincoln Peak to the south, the slopes of Mount Ellen are home to the Sugarbush Resort.

Another theory is that the mountain was named for Ellen Douglas, the heroine in Sir Walter Scott's poem The Lady of the Lake published in 1810.

On the west side of the ridge, Mount Ellen drains into the New Haven River, thence into Otter Creek, and into Lake Champlain.

[1] Part of Mount Ellen's eastern face is used for the ski trails of Sugarbush Resort.
