Perranuthnoe beach is located on the south coast around a mile to the east of Marazion, with fine views of Cornwall's jewel, St Michael's Mount. At low tide Perranuthnoe is a sandy beach with some shingle and at high tide, the beach is mostly claimed by the sea. The beach is a popular one with surfers.
Known by locals as Perran Sands, the beach can be confused with the beach of the same name at Perranporth on the north coast.
