Lagos is the western terminus of the CP Linha do Algarve regional train running to Faro and Vila Real de Santo António. Inside the municipality, the Onda municipal bus links the old town with Meia Praia, Porto de Mós and Luz, and a small ferry crosses the Bensafrim river to Meia Praia. Portuguese rules let small dogs in carriers ride free and accept large muzzled leashed dogs at off-peak hours.
Lagos centre · Estação de Lagos, Largo da Estação, 8600 Lagos
The CP regional line runs from Lagos to Faro in about 1h45 (around EUR 7.30 each way), connecting at Tunes to long-distance trains for Lisbon. Small dogs in carriers travel free; larger leashed dogs need a muzzle and a half-fare ticket, off-peak only.
Lagos centre · Estação Rodoviária, Rossio de São João, 8600 Lagos
The Onda municipal bus runs four colour-coded lines linking the old town, Meia Praia, Porto de Mós, Praia da Luz and the Ponta da Piedade lighthouse. Single fare around EUR 1.40; small dogs in carriers ride free, large leashed dogs accepted at the driver's discretion.
Marina de Lagos · Cais da Solaria, Avenida dos Descobrimentos, 8600 Lagos
A small passenger ferry crosses the Bensafrim river estuary from the marina-side Cais da Solaria to the Meia Praia dune end every 30 minutes during the May-October season. The 5-minute crossing avoids the 3 km walk around the marina and welcomes leashed dogs without charge.
