Been there last February…..not to much sightseeing, you can visit the whole island within a day…so, rent a car for a day and believe me is more than enough!!!
The windy days if you are not willing to kite in Santa Maria beach you can always get a taxi(4x4) to/from the kite beach at a cost around €10.
Njoy and pray to god for windy days….otherwise the place sucks and you ll get bored to death!!!!
