High above Crete's Lasithi Plateau is this extraordinary late Minoan site, slung across a strategic mountain pass with views to the sea below. It's a steep 30-minute walk up from the nearest road - though when I visited, I saw a man shepherding his goats on the plain below from inside his 4x4. The site was excavated by John Pendlebury, the archaeologist, whose grave you can see at the Allied War Cemetery at Soudha Bay.
Near Tzermiado village, Lasithi, Crete;
Yes, it's a worthwhile climb. You can take your car to the little whitewashed church at the bottom of the hill.
