My wife and I will be spending two nights in La Spezia in late August. Planning on catching first boat to Vernazza arriving 11:00am. Now I know that people can vary in their abilities to hike, so my wife and I are 36 and 37, reasonably fit. She teaches aerobics and I hit the gym daily. Neither of us are OCD about it, so we aren't runners or cyclists or anything like that but we would enjoy a good long sustained workout (ie sweating :-) Question: hiking south would put us in Corniglia next, but the boat does not pick up there. How long would the hike be from Vernazza to Manarola? Is it doable given the last boat pick up from Manarola that goes to La Spezia is at 5:30? If we cant make the last boat, the train would still run till late is that right?
