25th July. WARNING - contactless payment is NOT accepted on buses in the Algarve except for the 'Proximo' buses in Faro city. A pre paid pass for VAMUS regional buses is obtainable at bus stations which can reduce fares on their buses by around 40%. There is also an 'app' based account for VAMUS regional buses which can be used to the same effect. Summer timetables generally apply for the whole of July and August. Changes are very unusual at this time of year.
