The Portuguese Riviera is a term used in the tourist industry for the affluent coastal region to the west of Lisbon, Portugal, centered on the coastal municipalities of Cascais, Oeiras and Sintra. It is coterminous with the Estoril Coast and occasionally known as the Costa do Sol. Portuguese themselves do not use this expression.
