The rare anthodite formations found here are among the best specimens in the world and are nicknamed 'Orchids of the Mineral Kingdom'.
The caverns were discovered by Walter Amos in 1937 while he was prospecting for caves in the area.
Skyline Caverns contains three distinct underground streams that feed into a central subterranean lake.
The cave was formed in limestone deposits dating back over 400 million years to the Ordovician period.
The cavern system is located along the edge of the Blue Ridge Mountains, which influenced its complex geological development.
Skyline Caverns is a karst cave system located near the northern entrance of Shenandoah National Park. It is world-renowned for its rare anthodite formations, which are fragile, flower-like clusters of calcite crystals. The cave features a guided walking tour covering approximately one mile of subterranean pathways. An on-site miniature train operates outdoors, providing a scenic loop through the surrounding wooded grounds. The cavern remains at a constant temperature of 54 degrees Fahrenheit throughout the year. It also houses underground streams and a subterranean lake system.
The Cathedral Hall area, where the largest concentration of anthodites is illuminated.
Bring a light jacket or sweater, as the cave temperature is consistently cool year-round.
Wear rubber-soled walking shoes with good grip to navigate damp cave pathways.
Arrive early in the day during peak summer months to avoid the largest crowds.
Do not attempt to walk the trail without a guide, as the cave system is protected and gated.
Open daily year-round, except for Thanksgiving Day and Christmas Day.
Do not touch the cave walls or formations; oil from skin can permanently damage delicate mineral growth.
