The other photos have been geo-tagged as on or around the summit. For less busy mountains, it can be a little hit and miss.

Notes
- Data: Database of British and Irish Hills v18.2
- Maps: We use OS mapping for England, Scotland, Wales, and the Isle of Man. Sadly, Channel Islands, Northern (OSNI) and Southern Ireland (OSI) mapping isn't available online, so we use Openstreetmap.
