The Venetian Fortress towers over Nafplion, another reminder of the time the area was under their rule. Its thick wall provided protection from invaders but these days the gates are open and the invaders come in the form of tourists.
We did it with several 'breathing stops' on the way up. People who suffer vertigo might not want to make the climb, but then they shouldn't be going to the fortress if they don't like heights.. I have to be truthful and add that we both had wobbly knees by the time we returned to the roadway at the base of the cliff.
Each time we do something like this we comment that it is 'pretty good for people our ages'. That brag was tempered by a man we met heading up as we were heading down. The elderly white-haired man (much older than us) was dressed in slacks, dress shirt, sweater vest, jacket and used a cane. "Bon Jour, Madam" he called out to me as I passed.
