The locals seem to genuinely friendly, not just looking for your money. For instance, we asked at a working farm where to see a nearby Taula (prehistoric monument). The farmer stopped work to guide us over a wall, past a locked gate and into a private garden. And he admired our bikes!
Anyone who has anything to do with tourists speaks English, but Spanish comes in handy for encounters like the one just described.
The authorities take enormous trouble to remove litter and keep the place clean, and there appears to be almost no crime, although we were advised to lock our dinghy and bikes.
