The route
This is most of the Outmore NI route from Ballintoy Harbour towards Bushmills, following the waymarked Causeway Coast Way. The line shown ends at Portballintrae, a short distance before the official Bushmills finish, because that is where the mapped trail stops. It is a full day on rough coastal terrain, so plan transport at the far end.
The interactive map needs JavaScript. The start and finish are listed below.
Along the way
- Start: Ballintoy Harbour
- Finish: Portballintrae (Bushfoot Road)
The line is drawn from OpenStreetMap data and simplified to 464 points. It can differ from what is on the ground: waymarks and the official page take priority.
