Billing itself as the only national park to feature a city - lovely Norwich, this Norfolk national park has plenty of contrast too, with open wetlands and rural villages all along its length. Campsites in the Broads are the perfect resting place, letting you cruise more waterways than even the watery city of Amsterdam has to offer. As you take it all in, stop for fishing, regular jaunts on land and stargazing among these perfectly dark skies.
