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.

Covering 53.4 km, this is a true long-distance trail best approached as a multi-day journey through varied terrain.

This linear trail moves from one end to the other without looping back. A return journey by transport — or retracing the path — is needed to get back to the start. 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.
