Steel Rigg & Sycamore Gap loop from The Sill — Northumberland National Park

Embark on an easy 3.7-mile (6.0 km) hike along the Steel Rigg & Sycamore Gap loop, offering a blend of Roman history and dramatic landscapes. You will gain 294 feet (90 metres) in elevation over approximately 1 hour and 37 minutes, traversing varied terrain including footpaths, grassy banks, and some steep stone steps near Hadrian's Wall. The undulating path leads you to the iconic Sycamore Gap, a dramatic dip in the landscape, and provides sweeping views overlooking Crag Lough. Expect sections of dirt, grass, and rocks, with some parts potentially boggy, so wear appropriate walking boots. You will encounter stiles and kissing gates along the way, adding to the classic countryside experience.

This popular route starts conveniently from The Sill National Landscape Discovery Centre, a modern visitor hub that provides facilities and exhibitions before you set out. The trail is generally considered easy, making it suitable for those with a reasonable level of fitness who want to explore one of Northumberland National Park's most celebrated areas. Plan for a leisurely pace to fully appreciate the continuous views and historical points of interest.

The trail is highly notable for traversing one of the most spectacular sections of Hadrian's Wall, offering a tangible connection to Roman history and impressive ancient ruins like Milecastle 39. Despite the felling of the famous Sycamore Gap tree, the location remains iconic, still providing a dramatic landscape feature framed by sheer crags. You will also enjoy panoramic views across the Northumberland countryside, including the striking Crag Lough and rugged Whin Sill crags, combining historical interest with diverse natural beauty.
