Porthtowan is well-known amongst surfers for its beautiful curling waves when conditions are right. Porthtowan has two great surfing schools – Tris Surf Shop and Pure Blue Surf Academy(specialising in women surfers). All offer lessons, some hire out surfboards, body boards and wetsuits. Tris Surf Shop also sells clothing, surf wax and accessories. St Agnes offers another two surf shops.
For belly-boarding and body-boarding(often called Boogie Boarding) enthusiasts there are often opportunities to get on the waves with Belly boards and Body boards even when the waves are not suitable for surfing. Boards can be hired from Tris Surf Shop throughout the year.
