We are packing for 7 days of hiking in the Smokys. We will spend the first day in Elkmont and hope to see synchronous fireflies in the evening. Next day from Tremont to Spence Field via West Prong is tough, 14 km and 1300 m altitude gain, but then we hike forth and back on the Appalachian Trail on top of the range (right and left on the Google view), before walking down back to Tremont. Rain and bear activity in the forecast.
