Stunning coastal scenery including Giants Causeway and amazing weather for it too. Mainly coastal path although several long road sections but thankfully not much traffic.
Followed the gpx (as linked from LDWA and FKT) with a few amends: 1. Did it in reverse, 2. Started at Ballycastle Diamond as per guide and signage (their gpx started at a roundabout about half a mile into the route, assume their error), 3. Took the recommended (and lovely) Glenstaughey Road rather than busier A2, 4. High tide meant heading up for an additional road section to avoid drowning at Dunseverick, 5. The marked start/finish is at the end of the coast path before Portstewart Strand (their gpx went past this and on to a roundabout, assume their error).
Had one drop bag with energy drink at Portballintrae.
