This is a lovely walk and takes you out through Florence and then climbs up through relatively quiet roads to the village of Fiesole. Once out of the city you will pass by elegant Villas and Olive Groves.
Basically, keep going mostly straight and follow the directions exactly.
You can either return on foot or alternatively take a number 7 bus back to San Marco in Florence – you can buy a ticket which is currently €1.20 at a tobacconist. Be sure to validate your ticket on the bus.
