The Simonside Hills are composed of Carboniferous sandstone, forming a prominent scarp slope that overlooks the Coquet Valley.
The area is home to a significant population of red squirrels, which thrive in the neighboring coniferous woodlands.
The ridge features numerous Neolithic and Bronze Age cup-and-ring marked stones, particularly visible at the adjacent Lordenshaws site.
The summit, known as Simonside, reaches an elevation of 429 meters above sea level.
During the Second World War, the area was used by the RAF for navigation practice due to the distinct shape of the crags.
The hills form part of the Northumberland International Dark Sky Park, offering minimal light pollution for stargazing.
Simonside Car Park Walk serves as the primary gateway to the Simonside Hills within the Northumberland National Park. This trailhead provides direct access to a network of upland trails characterized by craggy sandstone ridges and sweeping moorland vistas. The terrain is defined by exposed rock formations, primarily the Simonside crags, which rise significantly above the surrounding forest and heath. The path leads hikers through a mix of coniferous forestry plantations before ascending into open fell land. It is a focal point for birdwatchers tracking upland species like curlews and golden plovers. The trails are part of a larger interconnected network that extends toward the Lordenshaws prehistoric rock art sites.
The summit trig point offering a 360-degree panoramic view of the Cheviot Hills and the North Sea coast.
Bring a physical map and compass, as mobile signal is unreliable across the ridgeline.
Check the local weather forecast specifically for the Simonside summit, as temperatures drop significantly compared to the valley.
Use the trail markers provided by the National Park to avoid wandering into sensitive boggy areas off-path.
Attempting the ridge scramble during heavy rain or high winds, as the sandstone becomes exceptionally slippery.
Wear sturdy, waterproof hiking boots; keep dogs on leads during ground-nesting bird season; follow the Countryside Code by taking all litter home.
