Lushington sits just to the west of the ever popular Porthtowan. At low tide you can just stroll around the headland and saunter up the sand, checking out all the caves and rocks. At high tide it’s only accessible via a skinny path (a technical Cornish term), which heads down a sheer cliff and has a rope handrail at the bottom to help with the ascent. The Black Dog managed it no problem – I can vouch it’s easier on all fours at points ;)
The beach is quite often completely deserted, with a shingle/sand sweep, littered with flotsam and jetsam, so great for beach combing.
