Plan Your Next Hill Day with the MunroMapping Route Planner

The MunroMapping route planner is targeted at people who spend their weekends in the hills and adventuring outside. It uses the same topographic map that powers MunroMapping, OS-style contours at 10m intervals, hypsometric colour shading, and cliff detail from OS open data. With the addition of interactive route planning with real elevation profiles on top.

How It Works

Click on the map to add waypoints. Each click adds a numbered marker and extends the route line. Drag markers to adjust your line. Click in the middle of two markers to insert a new point between two existing ones.

The elevation profile updates automatically. It pulls elevation data for your waypoints along the route, then draws a cross-section of the terrain you’ll be crossing. The profile shows total ascent, total descent, distance in km and miles, and an estimated time using Naismith’s Rule, 5 km/hr on flat ground, one minute added for every 10 metres climbed.

That last figure is worth treating as a floor, not a ceiling. Naismith doesn’t account for rough ground, river crossings, or the kind of weather that turns a straightforward ridge walk into something more demanding. But it gives you a baseline to plan around.

Summit Classifications on the Map

Six summit lists are overlaid on the map as colour-coded markers: Munros, Corbetts, Grahams, Donalds and Wainwrights. You can toggle each category on and off from the dropdown.

The markers don’t snap your route to anything, you control the line. But they make it straightforward to plan a route.

GPX Import and Export

Once your route is planned, export it as a GPX file. The exported file includes full elevation data, ready to load onto a GPS device or import into another app.

You can also import existing GPX files, either routes you’ve planned elsewhere or tracks from previous walks. Drop a file onto the map or use the import button.

The route planner is free to use at maps.munromapping.co.uk. No account required. Build a route, copy the URL, and share it directly, the full route is encoded in the link.

A Note on Accuracy

The elevation data comes from SRTM, the same satellite radar dataset used by most topographic mapping at this scale. At 30m post-processing resolution, it’s accurate enough for planning purposes but not a substitute for 1:25,000 paper maps or a properly calibrated GPS on the hill. Use it to understand the shape of a day, not as a precision instrument.

The planner works on mobile as well as desktop. On smaller screens the stats panel moves to a bottom sheet and the controls reposition automatically. We’d still recommend using it on a larger screen for route planning.
