Rainbow Springs has a bunk house, showers, laundry, and a store. For ya'll that have read "A Walk in the Woods" they are not the rat infested shiesters the book tries to portray them as.
Right beside the river with a nice front porch to dry your stuff under while you do laundry and eat a pizza, they are conviently located 1 mile from the trail.
Of course it is a bunkouse, not a Hilton, so don't expect room service and hot tubs.
