Frequently Asked Questions: Hills & Mountains
The distinction between a hill and a mountain isn't always clear-cut and often depends on local traditions and conventions. In the UK, many consider peaks over 2,000 feet (610m) to be mountains, but this isn't a strict rule.
Prominence measures how much a hill or mountain stands out relative to surrounding terrain. It's calculated as the vertical distance between a peak's summit and the lowest contour line encircling it but containing no higher summit.
Hills and mountains are grouped into classifications based on height, prominence, and other criteria. These classifications help hikers and mountaineers identify suitable peaks for their skill level and interests.
Trig points are concrete pillars installed by the Ordnance Survey to map the UK. They were used as fixed surveying points and are often found at the summits of hills and mountains, though many are now primarily historical landmarks.
Heights are typically measured using modern GPS and altimetric surveying techniques. Professional surveyors use precise equipment to determine elevation above sea level, often combining satellite data with ground measurements.
Many hills and mountains have names derived from different languages, such as English, Welsh, Scots, or Gaelic. These multiple names often reflect the rich cultural and linguistic history of the British Isles.
A summit refers to the highest point of a hill or mountain. It's the ultimate destination for most hikers and can range from a distinct peak to a broad plateau.
Most hills and mountains in the UK are accessible due to open access land laws, particularly in Scotland's right to roam. However, some may have restricted access during certain times or require specific permissions.
Unclassified hills and mountains don't meet the criteria for established classifications like Munros or Marilyns. This might be due to insufficient height, prominence, or other technical factors.
Use our filter to search for hills and mountains with shorter distances, lower heights, or gentle gradients. Look for well-marked paths and good access points, and always check weather conditions before setting out.
One of the steepest climbs is on Ben Nevis' Tower Ridge. For roads, Rosedale Chimney Bank in Yorkshire is among the steepest, with a gradient of 33%.
The highest mountains in each country are: Scotland - Ben Nevis (1,345m), England - Scafell Pike (978m), Wales - Snowdon/Yr Wyddfa (1,085m), and Northern Ireland - Slieve Donard (850m).
Topographical isolation refers to the distance to the nearest point of equal elevation. It helps indicate how distinct or independent a peak is from surrounding terrain.
Many hikers enjoy completing challenges such as the Three Peaks Challenge (climbing Ben Nevis, Scafell Pike, and Snowdon), Munro-bagging in Scotland, or regional peak-bagging lists.
Weather can significantly affect hiking conditions. Strong winds, rain, or snow can make hikes more challenging and potentially dangerous. Always check weather forecasts and be prepared for sudden changes in mountain weather.
