Introduction

Mammoth Cave National Park preserves the cave system and a part of the Green River valley and hilly country of south central Kentucky. This is the world's longest cave system, with more than 365 miles explored. Early guide Stephen Bishop called the cave a "grand, gloomy and peculiar place," but its vast chambers and complex labyrinths have earned its name: Mammoth.

However rough you "rough it", Mammoth Cave National Park has dozens of campsites for your adventure – in three campgrounds, in the backcountry, and along the rivers.

No matter the season, you'll love Kentucky's mild climate. Summers can be very warm with average temperatures in the upper 80s (upper 30s Celsius), but cool evenings are not unusual. For spring and fall, it's a good idea to bring a light jacket. In the winter, we get a moderate amount of snow, and highs average in the low to mid 40s (4°-7° Celsius). The wettest seasons are spring and summer, and the driest is the fall. Annual average precipitation 48 inches, including an average snowfall of 13.7 inches.
