September, October, and NovemberRed, orange, and yellow leaves decorate the forest canopy and reveal rolling hills and cliffsides as they fall. Late fall may bring frost flowers, delicate ice crystals emerging from plants, that appear in the cold morning temperatures, only to melt away by the afternoon. Cooler temperatures on the surface are welcomed by hikers and the popularity of cave tours remain high during the autumn season. NPS Photo/ Jackie Wheet Cave ToursThe shoulder season of autumn brings changes to cave tour variety and frequency, but visitation to the park can remain high — especially in the early fall. Tour tickets oftentimes will sell out in advance on holidays and during local schools' fall breaks. Reservations are always recommended since purchasing your cave tour tickets in advance is the only way to ensure a spot is available for your party. Availability of walk-up tickets is not guaranteed. Camping and LodgingAs the busy summer season starts to wind down, the park campgrounds take on a quieter pace. The Mammoth Cave Campground and Maple Springs Campground close for the season on November 30 and will not reopen until March 1. The Houchin Ferry Campground near the town of Brownsville, Kentucky remains open year-round.

During the first half of the season temperatures are still comfortably warm with daytime highs averaging in the 70s Fahrenheit (21.1°C) and nighttime low in the 50s Fahrenheit (10°C). As the season progresses the temperatures continue to drop bringing lows closer to freezing (32°F/0°C) in the latter half of the season. See Fall ColorsThe changing colors of leaves are often sought out by photographers and sightseers, but in this area of the state that annual color show doesn't usually begin to occur until late October. Taking a ridge-top hike to Sunset Point along the Heritage trail can give you easy access to a view of the colorful hillsides or taking a scenic drive to one of the three remaining historic churches in the park will give you a front row seat to the pops of color throughout the park. ![]() NPS Photo/ Kait Evensen Things To DoAutumn is a popular time for hiking, with sparser foliage and cooler night temperatures ticks are much less plentiful, making the sunny days and changing colors even more worthwhile. More comfortable weather means a good time for longer visits to the backcountry on bike, horseback, or on foot. Make the Most of Your Visit
