We're going to be in Perranporth next week and are looking to have a day without using the car after a long drive there. I've seen mentioned a coast walk from Perranporth to St Agnes, going past old mining relics and along the cliffs, can anyone give me more details on this? I assume it's part of the SW Coast Path. Is it doable in normal shoes or sandals, or is it rough terrain and we should bring walking boots? Also, is it possible to make it circular? Any insight or alternatives welcome! Thanks!
