Seven species of reptiles and amphibians are found in the park. Although they are widespread through the park at elevations below 7,000 feet,
their numbers are few.
The valley garter snake is the only species of snake which occurs naturally in the park. It is relatively uncommon and generally inhabits the shores of Crater
Lake, Wizard Island, and other watercourses and bogs within the park.
The Crater Lake newt (Taricha granulosa mazama) is the only amphibian in the park that is considered to be rare. It is a subspecies of the rough-skinned newt and is
found only within the shoreline ecosystem of Crater Lake.
