What is the best time to explore Northumberland National Park?

Visitors can enjoy tranquility and seclusion year-round in Northumberland National Park, though the sights and delights of summer still bring their fair share of holidaymakers. Adventurers who aren’t put off by a cold wind will find plenty to explore during the winter season, which begins in October, when wintering birds arrive in the dozens and the remote landscape is blanketed by the occasional falling of snow.
