Other Activities in the Great Smoky Mountains National Park Horseback Riding . About 550 miles of the Park's hiking trails are open to horses. Use of the horse camps requires a reservation. The Park also has five commercial stables within its borders. They are open from approximately mid-March through the Thanksgiving season.
Swimming is a favorite way to escape the summer heat.
However, Park waters are dangerous and caution is a must. Swim at your own risk, and watch children carefully. The Park does not recommend any specific swimming area for this reason. Since Park waters rarely rise above 65F degrees, hypothermia is a year-round risk. Practicing Water Safety is a must while visiting the Park.
