G Adventures started offering tours in 1990 and it has grown into a large and popular tour company that offers trips around the world. The company focuses on small group tours that let travelers experience the culture and environment of a country.
G Adventures offers a wide variety of tours to Italy that range in length from under a week to almost a month. There are tours that combine Italy with several nearby countries and tours that focus exclusively on Italy.
If you're interested in exploring Italy in depth, then there are several great options through G Adventures. There are "classic" routes that start in Rome and visit Florence, Siena, Pisa, Cinque Terre, Lake Como, and Venice. There are tours that spend most of their time in Florence, Siena, San Gimignano, and Montauto. There are tours that stay along the coast and visit Naples, Pompeii, Sorrento, Capri, and Positano. There's also a "best of Sicily" tour that visits Catania, Syracuse, Scicli, Modica, Ragusa, Palermo, and Mt Etna.
If you want to experience more of Europe, there are more wide-sweeping tours. There are tours that go to nearby France and Switzerland and tours that go through Austria to Hungary. There are month long tours that go through many major European cities or tours that travel from Rome to London.
Regardless of how much time you have or how in depth you want your experience to be, there is like a tour offered by G Adventures that meets your needs.
G Adventures has values that include sustainable tourism and environmentally conscious travel. The hotels they use are often basic, but locally owned. This is not the cheapest tour company, but their focus on their values and the customers experience make it worth the slightly higher price tag.
