Located in the Breadloaf Wilderness of the Green Mountain National Forest, its summit is in the town of Lincoln in Addison County.

The mountain is named after Ulysses S. Grant, former president of the United States.

Mount Grant stands within the watershed of Lake Champlain, which drains into the Richelieu River in Québec, the Saint Lawrence River, and then eventually into the Gulf of Saint Lawrence.

The south and west sides of Mount Grant drain into the New Haven River, thence into Otter Creek, and into Lake Champlain.

From the summit, there are views south across the Breadloaf Wilderness towards Bread Loaf Mountain.
