The Green Mountains are located in the northeastern United States, specifically in Vermont, and are part of the Appalachian Mountain range.

The Green Mountains are a prominent subrange of the Appalachian Mountains in Vermont. Known for their dense forests and scenic beauty, they play a significant role in the state's identity, even lending their name to Vermont ("Vert Mont" meaning "Green Mountain" in French). This range includes notable peaks such as Mount Mansfield and Killington Peak, which attract hikers, skiers, and nature enthusiasts. The Green Mountains are distinct from other Appalachian subranges like the Adirondacks or Blue Ridge Mountains, as they occupy the northeastern segment of the range and are characterized by a cooler climate and unique ecosystems.
