Buggytop Trail and Natural Bridge. Sewanee. 4.5 miles. Moderate. We will hike to Lost Cove Cave on the Buggytop trail. This is one of the plateau’s most impressive cave entrances. The mouth of the cave is carved out of a 150-foot cliff. After hiking the Buggytop Trail, we will stop at the Sewanee Natural Bridge State Natural Area to see the largest known natural bridge in the South Cumberland area. We plan have lunch in Sewanee at Shenanigans Restaurant. For more information or to sign up, contact Sara Pollard at 615-714-3610 or email@example.com.
