Greenwich Meridian Trail

A long-distance walk that follows the line of the Prime Meridian. Inaugurated in 2009, to coincide with the 125th anniversary of the Greenwich Meridian.

This 54.5 km route is a major undertaking — excellent fitness, reliable navigation, and multi-day planning are required. End-to-end time is roughly 12 hours and 7 minutes.

Point-to-point in layout, this trail takes you from A to B across the landscape. Consider your return logistics before heading out. Follow the GMT waymarkers throughout to stay on the official trail line.

This trail forms part of the Regional Walking Network (RWN), linking local communities and natural features across the region. Waymarking is managed at the regional level.
