Bergamo is a pretty town of some 120,000 people nestling in the foothills of the Alps. Widely acclaimed as a city of rare beauty, Bergamo is famous for its wealth of artistic treasures and enchanting medieval atmosphere. It is a real life tale of two cities: “Città Bassa”, the busy and modern lower city, and "Città Alta", the upper city with its rich heritage of art and history.
Bergamo is the location of the Orio al Serio International Airport (IATA: BGY) (Phone number: +39035326323), an airport oriented around low-cost airlines (Discount_airlines_in_Europe). ATB no.1 bus to the city are €2.10 per trip, €5.00 for 24h ticket and €7.00 for a 3 days ticket. There is a ticket machine at the bus stop or you can buy the tickets at Tourist Information Point office . You can find schedules and route maps on the site of ATB  the local mass transit authority.
Cabs will take about 15 min but are quite expensive given the length of the journey - cost around €15 (€21 after 21:00 in the evening).
Note that buses can be both unreliable and not punctual. You'd better take the no.1 city bus 30 or 45 minutes before the time you actually have to be at the airport.
Milan is about 50 minutes away by train. There is no train station at the airport in Bergamo. The 1-airport bus to Bergamo city, taking around 20 minutes, leaves you just in front of the train station. From Bergamo city regular trains to Milan, Lecco and Brescia, on to Verona and Venice. You can check schedules and fares on the website of the Italian Railways . There is no left luggage office at the train station but you can leave your bags just 50 metres outside in the automatic left luggage behind URBAN CENTER and behind McDonald's . Alternatively, you can leave them in the airport, but it's rather slow and works just in the daytime. If you are at the airport and your destination is Milan or Venice, just take one of the regular coaches. However be warned that the autostrada connecting Bergamo and Milan carries a lot of trucks and gets easily congested - do not therefore rely on the 'stated' journey time especially on weekdays. An alternative is to take the bus into Bergamo (see above) and take the train.
Regular buses to Milan. You can check schedules and fares on the website of Autostradale . The trip takes approximately one hour, depending on traffic conditions. The bus stop in Bergamo is located near the train station and there is a counter where inquiries can be made.
Here you can found a very interesting service: a Mini Electric car and Electric Bicycle rental that permit to visit the upper town without limitation of traffic circulation and pollution rules. Renting a car is possible for just €5 per hour or €39 a day.(http://www.eco-rent.it)
The town is not large, and most of the sights can be seen comfortably on foot. To get from the Città Bassa up to the Città Alta can be quite tiring on foot, though, due to the steep and winding streets, but there is a funicolare (or cable railway) linking the two parts of the town. You can see a map of bus routes, schedules and fares on the website of the local mass transit authority  (in Italian). The ticket that you purchase for the funicular is valid for 75 minutes and you can reuse the same ticket for travel on the network, including the funicular to San Vigilio. Walking from the train station to the Città Alta funicular station is pleasant and takes about 20-30 minutes. You can also walk from Città Alta to San Vigilio instead of taking the funicular, which will afford you great views of the surrounding areas, as well as the quaint narrow streets and houses along the way.
The Piazza Vecchia - the heart of the old town, displaying a mix of medieval and Renaissance architecture. Piazza Vecchia is the genuine heart of the city. Its beauty and the balanced proportion of volumes and lines that make it unforgettable are not the result of the genius of some architect, but are due to its shaping by generations of Bergamask people, in a succession of art and history. Your eye is immediately drawn to the beautiful white marble Contarini fountain in the centre, and the alignment of the buildings along the two sides directs your sight towards Palazzo della Ragione (Palace of Reason) at the end of the square. The facade of this twelfth century building is dominated by the symbolic lion of Venice, a reminder of the centuries of historic, cultural and economic relations between the two cities. Standing tall in a corner is the Civic Tower, known also as the “Campanone”, or big bell, a landmark infused with civic meaning, as demonstrated by the 180 times the large bell tolls each evening to mark the ancient curfew. This square was the seat of political and administrative power until the nineteenth century, and is overlooked by Palazzo del Podestà, the residence of Venetian rulers, and the Town Hall, which can be identified by its impressive marble façade and which today houses the Civic Library.
