/ Where to get jetboil gas in el chorro spain
Just buy a cheapo gaz stove, either at home or Deacathlon when you get there
there a probably a few places in Malaga...i seem to remember a climbing shop in a shopping centre near the train station.
Buying a stove there is a good option.
If you have an hire car, Decathlon is just around the corner from the airport. Just head towards San Julian village, then follow the signs, two minutes in the car.
