Calculate straight-line and driving distance between any two mountain peaks
The Summit Distance Calculator computes the geographic relationship between any two mountain peaks in the MountainFYI database. It provides three distance measurements: straight-line (great-circle) distance between summits, approximate driving distance between the nearest trailheads, and driving time estimate. This helps hikers planning multi-peak trips understand the logistics of getting between mountains.
The tool displays results on an interactive map showing both peaks with a connecting line for the straight-line distance and a road route for the driving distance. Elevation profiles for both mountains appear as markers on the map, providing visual context for the geographic relationship.
Beyond simple A-to-B calculation, the tool supports route planning for peak-bagging challenges. Users can input a series of peaks and see the total driving distance for a road trip connecting them in optimal order.
The calculator integrates with challenge lists — loading the 'National Three Peaks' challenge automatically populates Ben Nevis, Scafell Pike, and Snowdon and shows the optimal driving route between them.
วิธีการทำงาน
- Enter the first mountain name — autocomplete suggests matching peaks
- Enter the second mountain name
- The tool instantly calculates straight-line distance (great-circle on WGS84 ellipsoid)
- View both peaks plotted on an interactive map with a connecting line
- Click "Show Driving Route" to calculate road distance and estimated driving time between nearest trailheads
- Optionally add more peaks (up to 15) for multi-stop route planning
- Click "Optimize Order" to find the shortest total driving distance between all selected peaks
- Toggle units between kilometers/miles and hours/minutes

กรณีการใช้งาน
- • A hiker planning the UK Three Peaks Challenge loads the challenge preset and sees the 462-mile total driving route with per-leg times (Ben Nevis → Scafell Pike: 5h, Scafell Pike → Snowdon: 4h)
- • A Korean hiker wants to know how far apart Hallasan and Jirisan are — the tool shows 238km straight-line and 4.5 hours driving via ferry + highway
- • A Colorado 14er bagger planning a summer road trip selects 8 fourteeners and uses 'Optimize Order' to find the shortest loop starting from Denver
- • A European alpinist comparing Mont Blanc and the Matterhorn sees they are 67km apart straight-line but 230km by road through the Mont Blanc Tunnel
- • A geography teacher wants to show students that K2 and Everest are only 1,360km apart despite being in different countries
