where do groundhogs hibernate

Groundhogs hibernate in underground burrows that they dig themselves, usually in well‑drained soil at the edge of fields, pastures, or woodlands.

Quick Scoop: Where Do Groundhogs Hibernate?

• Groundhogs spend winter in deep underground dens, often 20 inches to 3 feet below the surface, where the temperature stays more stable than above ground.

• These winter burrows are usually separate “winter dens,” often placed in wooded or brushy areas and dug below the frost line so they stay above freezing.

• Inside, the hibernation chamber is lined with dry leaves and grasses, forming a cozy, insulated nest.

• They plug the entrance with soil, leaves, and other material, which helps keep out cold air and predators.

• You’ll often find burrow entrances near trees, fences, stone walls, field edges, or building foundations where the soil is easy to dig but still stable.

A Tiny Winter Bunker

Think of a groundhog’s hibernation den like a small, hidden underground bunker.
One main entrance (about 10–12 inches wide) leads down through tunnels to a special hibernation chamber, lined with plant material and sealed against the worst of winter weather.

During hibernation, the groundhog curls up alone in this chamber, its body temperature and heart rate dropping dramatically while it sleeps through the coldest months.

TL;DR: When you ask “where do groundhogs hibernate,” the answer is: in deep, well‑insulated underground burrows they dig in open fields and woodland edges, often in a special winter den below the frost line.
