If you're hiking the Appalachian trail, Caledonia is an oasis. Take a moment to cool off in the shallow river, or even pay to go into the pool (real shower and bathroom included!). Continuing northbound on the AP will bring you to the nicest shelter on the entire trail (IMO). If you can make the additional six miles past the rocky mountain shelter, do it. Caledonia itself has camp sites with hot showers if you want to detour a little off the trail for the day.
