Hopefully off to Sardinia in March & Aberdeenshire a bit later in the year. Another one or two trips to Spain will almost certainly happen. I might see some of Ireland too :-)
Sardinia is magnificent: absolutely littered with sites in all stages of of preservation from untouched tumbledown to pristine reconstruction. Neolithic and Bronze Age. Odd little rocks, stone rings, holy wells, rock cut burial chambers, huge stone towers.
Plus, some of the best eating and drinking on the planet. Have a great time.
