Minorca/Menorca is riddled with sites to enjoy the Talayotic culture. There is even one AT the airport road so you could basically fly in, walk 10 minutes or less and "tick" this off. I actually did not check this one out because I had a car and was recommended a lot better things from the lady at the car rental. It is also a massive change in tourist numbers from the nearby islands, so calm and relaxed.
I drove to 3 places. Two "rubble", not that interesting, and tough to park, free of entry like most sites on the islands (if not all?). It really only takes a few minutes to walk around these and the grass wasn't cut so not much fun. The third place, much more interesting, was the Cales Coves Necropolis. You can park and walk down with some shades paths and mostly flat, enjoy a sit at the playa, see some of the necropolis on the way and in the bay. Yes, they are just caves now and you cannot even go up there but it gives you an idea that the culture was present everywhere on this island. The area was an anchorage for trading boats and then re-used in Roman times as a sanctuary. A couple had brought their kayak and I was a bit jealous they can go out into the blue sea on this chilled out, underrated island.
In retrospective I should have sought out a museum to complement my visit.
