This outdoor 'gypsy' market is held every Wednesday morning. It is now located at Fonte Santa, about 1 mile/1.6km east of the town on the road towards Almancil.  http://goo.gl/maps/GK6eF (green arrow)

There is a fairly large parking area next to it. When coming from Quarteira, look out for the LIDL store on the left. The market site is about 100 metres further down the road past the crossroads and a small group of buildings.

Many local tour companies organise trips, but it can be cheaper and is more flexible to go on the local buses. The location is served by the buses running between Quarteira, Almancil and Faro, which run every 30 to 60 minutes.

There are a couple of bars and restaurants in the immediate area.

When in the market, beware sellers of counterfeit goods and especially cheap cigarettes. The unwary will be fleeced/diddled/stung.
