Planning to spend 2 weeks this summer in southwest England. Want to hike, bird and explore in Exmoor and Dartmoor National Parks. We are seeking solitude! Defintiely want to avoid crowds, kids and "tourist traps". Have read that southwest England is overrun with vacationers in July. Is this true even in early July?? When does the school year end? I thought August was the big vacation month in the UK.
