Brougham Castle is a red-sandstone castle standing near the site of a Roman fort, guarding a river crossing south-east of Penrith. It was founded in the early 13th century by Robert de Vieuxpont, and his great keep still dominates the site. The powerful Clifford family later added more buildings, including an unusual double gatehouse and the Tower of League.

Tip: Head up the spiral stairs to the top of the keep for panoramic views over the Eden Valley.

Lowther Castle is a ruined country house near Penrith, built in the early 19th century and left as a dramatic shell after the roof was removed and the building demolished in the 1950s. You can explore the ruins, then wander the 130 acres of gardens, which include the Parterre, the Garden-in-the-Ruins, the Rose Garden, wildflower meadows and rambling woodland.

Tip: Walk out to the Western Terrace for a spectacular view over the Lowther Valley to the Lake District mountains, and dress for all weathers.

High Force is a waterfall on the River Tees, near Middleton-in-Teesdale in the North Pennines Area of Outstanding Natural Beauty. The whole river plunges 70 feet over a cliff edge in two stages. After heavy rain the river also flows over the usually dry right-hand channel, making two falls. In harsh winters the falls have been known to freeze into cathedral-like ice formations.

Tip: The southern bank is free via the Pennine Way; the northern bank is a private Raby estate path with a fee. Visit after heavy rain to see the extra side channel flowing.

The Bowes Museum is an art gallery in Barnard Castle, County Durham, built in the style of a French château and set in landscaped parkland overlooking Teesdale countryside. It was purpose-built to house the collection of John Bowes and his wife Joséphine, and opened in 1892.

Tip: Check the museum's website for the current Silver Swan showing times before you go, as they differ on bank holidays and school holidays.

Carlisle Castle guarded the western end of the Anglo-Scottish border for hundreds of years and survived seven sieges by the Scots between 1174 and 1461. It was later adapted for artillery, and in 1568 it held Mary Queen of Scots prisoner. It stayed in military use well into the 20th century.
