We're heading to Menorca next week, staying in Ciutadella for 5 nights. Neither of us drive, so we intend to get to the island's beaches by bus or taxi. I'm just wondering if it's possible to get to Cala Turquetta or Cala Macarella (which look like the two nicest to us!) via bus or taxi, and roughly how much it would cost? Any help or advice would be greatly appreciated.
