Hi walkerman.
Few years back I enquired for a flying site ..As I fly model Heli's was along the N332 from Villa martin to Guardimar...
drive with the sea to your right and just before you get to guardimar on the N332 there is a market on the left ..if you past that, there
is a dusty road next to the market and there was supposed to be a sigh there ...not sure if its still there now ...worth a drive over !
Hope this helps ...if you find another plse let me know ...tks
