We went a few years ago and it was about 35 euros each way. We booked it before we went and never had any bother. The driver stands with your name on a piece of card and it is so much easier than fighting to get a taxi or bus when you get there.
thanks, we have pre booked privately before in tenerife but found out off other holiday makers it was much cheaper to queue up for taxis.
ive looked into pre booking it as there are 8 of us travelling, prices are between 100- 135.00 pounds return, which is a bit dear as its only 25 mins away, just want to compare prices see which will be cheaper, and not get ripped off when we get there!
