Me, DW, DS, DD, are looking forward to camping somewhere new. I am planning to take a 3-4 night trip to Cumberland Gap National Historic Park, for Spring Break, in early April. I am considering staying at the Wilderness Road CG, which is FCFS. Are main camping activities are hiking and swimming. Does anyone have input about the park and cg? Do sites fill up fast? Are their any features or hiking trails that are a must do?
