A packtrain of llamas is used to carry bed linens and supplies to Mt. LeConte Lodge. The llamas are easier on the heavily used Great Smoky Mountains National Park trails than horses.
In the picture below the llamas are passing behind Grotto Falls. Normally, the packtrain makes the trip from the Grotto Falls Parking area on the Roaring Fork Motor Trail on Monday, Wednesday, and Friday. Departure is often just around daybreak, and return between 3:00 and 5:00 in the afternoon.
