Walking from Whitesands Beach

The route from Whitesands Beach car park is about a mile and crosses undulating ground. Follow the footpath closely: Coetan Arthur is not easy to spot if you stray from the route. Before descending towards the path to Porthmelgan Beach, the monument can be seen to the northwest. From there, one option is a steep path up to the site; another is to continue around the headland on the coastal path.
The surrounding paths also lead towards Carn Lidi, where concrete bases from a Second World War radar station remain on the western face. The headland has further historical sites and coastal viewpoints, so the walk can take in more than the burial chamber.
