Each year in mid- to late April, the Great Smoky Mountains National Park hosts the Spring Wildflower Pilgrimage. It attracts wildflower enthusiasts from all over the country for five days of wildflower and natural-history walks, seminars, classes, photography tours, and other events. Instructors include National Park Service staff, along with outside experts. Most activities are at various locations in the park, both on the North Carolina and Tennessee sides, but registration
is in Gatlinburg at the Mills Conference Center. Begun in 1951, the pilgrimage has grown to more than 150 different walks, classes, and events. Advance registration online begins in February of the year of the conference, and some events quickly sell out. Check the website for current details and dates.
