The summer months are often the busiest and hottest; spring and September have fewer crowds and just as much sunshine.
Getting there
Planes
Fly into Rome’s Fiumicino Airport, then it’s an hour and a half or so by car to Porto Ercole. You could also fly into Pisa International Airport, which is just over two hours’ drive away.
Trains
Trenitalia and Italo run several daily services to and from Orbetello, which is a 15-minute drive away. Fiumicino Airport is a two-hour rail journey; stations in central Rome, Pisa and Siena are under two hours away; and trains run to cities further away, such as Florence or Naples, too.
Automobiles
A car is recommended if you’re planning on exploring the rest of Monte Argentario, plus Grosseto and the Maremma National Park are less than an hour’s drive away.
