Great Smoky Mountains National Park – Tennessee and North Carolina
Literally within a day’s drive of half the U.S. population, the Great Smoky Mountains is the most visited national park in the country. Along with over 800 square miles of terrain and hiking trails spread across some of the oldest mountains on Earth, the 62nd annual Spring Wildflower Pilgrimage, April 25-28, features 134 walks and programs led by rangers, botanists, entomologists and naturalists.
