Where are the flea markets and car boots in Tenerife ?

Been holidaying in Tenerife for years but never really discovered the regular fleamarkets and car boots?   Can anyone tell us where they are?    We will be here for a month as usual from mid January to mid February at Costa Adeje, will travel all over the island...Please please someone give us the info.........Thanks in advance

Welcome to the forum.

Have you tried a Google search. I am not in Tenerife but found heaps of markets on trip advisor.
