I could show you the sweeping, sandy beach of Praia Joaquina, a famous surf spot. But instead, this is a photo where it looks a little otherworldly. In addition to its surf fame, it's also famous for its sand dunes. People go sandboarding on these giant, pure sand hills - not me, though. I hated my one snowboard experience, and I don't think getting sand in my eyes would improve it.
This is a little ways back from the beach, in between the dunes and the shore.
