Concierge.com's insider take:
To escape the congestion of Ambleside and Langdale, head to this well-preserved fort. Known in Roman times as Mediobogdum, it was built at the same time Emperor Hadrian began his great coast-to-coast wall to the north. The fort commands a vast panorama from the mountains to the sea, and the lichen-mottled foundations are still a good vantage point for viewing the River Esk below. The site is owned by the National Trust and administered by English Heritage.
