Reopening: Great Smoky Mountains National Park reopened select roads, trails, restrooms, and picnic areas on May 9. The park is also issuing backcountry permits, and the LeConte Lodge, the park's official lodging option, will reopen May 18. However, visitor centers and campgrounds remain closed. The park also canceled its popular synchronous firefly viewing event, when shuttles take ticketed visitors to the Elkmont section of the park in late May and early June to witness tens of thousands of fireflies.
