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.

At 98.3 km, this is a demanding long-distance hike that may be split across multiple days. Experienced hikers typically take around 21 hours and 50 minutes to complete it end-to-end.

As a linear trail, this route has distinct start and end points. Return transport is worth arranging in advance unless you plan to walk back the same way. 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.
