Bradenton's best break for surfers seeking a little punch is Twin Piers. Don't let the name fool you; there are actually three, so keep that in mind as you head south on the beach road. Like most Southwest Florida surf spots, Twin Piers works best with higher water, so check it out on a N wind with an incoming to high tide. If you run into a crowd, keep looking north or south.
