The charm of Búzios lies largely in its beaches, the 20 stretches of sand large and small within a few kilometers of the old town. Thanks to the irregular topography of this rugged little peninsula, each beach is set off from the other and has developed its own beach personality. Farthest from the old town is Manguinhos beach. Sheltered from the heavy surf, this gentle beach is where many learn to sail and windsurf. A short hop over the neck of the peninsula lies Geribá beach, a wonderful long stretch of sand facing out towards the open ocean. This is the beach for surfing, boogie boarding, and windsurfing (see "Outdoor Activities & Watersports," below). Closer to town is Ferradura or Horseshoe beach. Nestled between rocky headlands in a beautiful horseshoe bay, this beach offers calm, crystal-clear waters, making it the perfect place for a long lazy afternoon's snorkel. Tiny and beautiful, Olho de Boi or Bull's Eye beach is tucked away on its own at the far end of a small ecological reserve. It can only be reached by a 20-minute walk from surfers' favorite Brava beach. Thanks to this isolation, Bull's Eye beach has been adopted by Búzios' clothing-optional crowd. Back on the calm inland side of the peninsula, João Fernandes and the pocket-size João Fernandinho beaches are busy, happening places lined with beachside cafes and full of people intent on getting and showing off their tans.
