Rio's beaches are neighborhoods with sand — each posto number has its own tribe.
Ipanema, Posto 9
The classic scene: bronzed crowds, biscoito globo and the two peaks watching.
Copacabana's curve
Four kilometers of mosaic promenade — walk it end to end at golden hour.
Arpoador
Surfers at dawn, sunset applause at dusk, and the best people-watching rock in Brazil.
Prainha
A wild, forest-backed cove past Barra — weekday mornings are magic.
Grumari
Even further, even emptier: red sand and no buildings in sight.
