Every town and village in Spain has its general market day where you can buy fresh fruit, vegetables, clothes and household goods. The fruit and veg stalls are filled to the brim with all kinds of produce - most of which will have been picked locally within the last couple of days.
The other type of market that you should pay a visit to is the 'rastro' or flee market. There are several in the area but the best of them are held in Jalon on a Saturday morning and Benidorm on a Friday evening. Here you can find anything from a odd tool bit for a out of production drill to beautifully carved wooden doors. Here also you will find the many Peruvian stalls selling brightly coloured cardigans and scarves and the haunting pipe music for which the country has become known.
It pays to know in advance when these markets take place, not only because of the bargains that can be found, but also because if you unwittingly park your car the night before in a street designated for the town market, you will wake up to it having been towed away to the local pound which will cost you the best part of 100€ to get it released.
