No special access issues
Park in the village car park (pay & display). Or the free parking along the road near the castle.
Walk to where Atlantic Road turns a corner towards the castle hotel. Continue straight down the track, past the Headland Camping & Caravan Park sign. Go along the side of the field until you reach the coastal path. Follow this left for ~250m until you reach a small often overgrown path heading down towards the ocean. Scramble down the obvious path until the boulders come into view.
The walk in is not tidal.
