Its mainly Bantham, Bigbury, Challaborough, Wembry, and Witsand, (moving east to west). Bantham is the best beginner beach, bigbury can sometimes produce better beginner waves than bantham and has a good tea shop (but Bantham is more consistent), (google "loving the beach venus"; there is a webcam but you need to register). When Bantham/Bigbury is too big, Challaborough can work as it faces a different direction; either from the Bigbury end or Challaborough village itself. Wembry is just outside Plymouth near Plymstock but I would not recommend it as there is no beach and water breaks on rocks. It also has to work to be worthwhile and is always busy as its close to Plymouth. Witsand, 7 miles outside Plymouth on the Torpoint side has miles of beach. Its more exposed than Bantham so weather and wave direction affects it more than bantham. However, I've had some very nice sessions there too. Witsand is usually very busy near the fort and sometimes the military close access. If you go a little further there are numerous access points to the beach and when its on, everything on 5 miles works well. Watch out for rips at Witsand and Bantham; they do not pose a problem once you understand them but Ive had to help people who has exhausted themselves swimming against the tide. Magic seaweed has webcams for Witsand and Bantham so you dont end up wasting petrol getting there. Happy surfing
