We want to visit gardens such as Hadrians villa, Villa D'este, Ninfa, Primavera, Castille Di Fume, Orsini. These are names we have picked out of brochures. Is there a book(let) detailing where the gardens are, opening times and details of how to get there? Should we base ourselves in Rome and travel by public transport? Is it do-able? Are there any garden tours run by tour operators?
