Macaé, Brazil

This is an oil town that grew too fast. Macaé, Brazil boomed when Petrobras set up shop, but infrastructure hasn’t kept pace—expect potholed streets and spotty public transport. The petroleum money means decent supermarkets and some international schools, but don’t expect cosmopolitan comforts. Portuguese is non-negotiable here; English gets you blank stares at the bank or pharmacy.

Beach lovers gravitate toward Cavaleiros, but the water quality suffers from occasional oil spills. The União Biological Reserve is the real draw if you care about wildlife. Rent is cheap, but vet landlords carefully—the 600% population surge in a decade means some buildings were thrown up fast. This place works for oil industry contractors or Portuguese-speaking FIRE types who want low costs without Rio’s chaos.
