An abundance of wildlife call Lava Beds their home, including many species of mammals such as bats, squirrels, bobcats, or mountain lions. Over 15 species of bats inhabit the caves. Park staff works year-round to monitor and protect the bats and their habitat, the lava tube caves.

Reptiles including snakes and lizards, amphibians like the Boreal and Pacific Tree frogs may also be spotted as you explore the caves.

This is a birder's paradise where you may spot prairie falcons, purple martins, sage thrasher and great-horned owls. Located along the Pacific Flyway, early spring and summer are great times to see waterfowl such as Canada geese. The Lower Klamath Lake Refuge borders the park and offers spectacular bird watching as well.
