Extending the length of Vermont, the Green Mountains rise toward Mount Mansfield at 4,393 feet, where rare alpine tundra survives along rugged cliffs. The Long Trail, established in 1910, follows this range’s ridgeline. It highlights its role as Vermont’s defining natural corridor and most recognizable mountain environment.
Virginia's The Great Channels
Although Shenandoah National Park anchors Virginia’s mountain scenery with its Blue Ridge vistas and a 105-mile stretch of protected wilderness, the Great Channels highlight an even more unusual geologic setting: narrow sandstone passageways carved by ancient forces atop Clinch Mountain. Their maze-like corridors create one of Virginia’s rarest natural features.
Washington's The Enchantments
High in the Alpine Lakes Wilderness, the Enchantments basin holds dozens of glacial lakes surrounded by sharp granite peaks and bright alpine meadows. Its turquoise water and fragile high-country terrain make this the premier wilderness destination in Washington, accessible only through a demanding permit-controlled trail system.
West Virginia's Dolly Sods Wilderness Area
Dolly Sods rises above 3,000 feet as a high-elevation plateau marked by heath barrens and boggy mountain meadows. Its alpine-like terrain contrasts sharply with the state’s river gorges for panoramic views and rare plant communities.
Wisconsin's Cave Of The Mounds
Cave of the Mounds reveals stalactites, stalagmites, flowstone, and clear underground pools shaped within Wisconsin’s karst limestone. Year-round guided tours explore chambers filled with colorful mineral formations, highlighting the slow geological processes that created the state’s most celebrated show cave.
Wyoming's Yellowstone National Park
Designated in 1872 as the world’s first national park, Yellowstone National Park spans more than 3,468 square miles.
