Security in Vilamoura is enforced and monitored by law enforcement at a high level to match the reputation of the elite resort of southern Portugal. Vilamoura is part of the golden triangle of Algavre in terms of tourist traffic and demand. There are no dangerous neighborhoods in Vilamoura, and the town itself is considered open, relaxed and friendly.
But it's worth following basic safety rules: keep a close eye on your belongings, don't hang bags and cameras on chairs in cafes or restaurants, and don't carry wallets and purses in backpacks or back pockets of pants.
Also carry a certified copy of your passport with you at all times - in Portugal, everyone must carry an identity document. You should also be aware that smoking in public places in Portugal carries high fines.
