The public transport system in the city center of Cologne is affordable, clean and efficient. In Cologne, visitors will find a range of public transport options including trams, buses, and suburban railways. S-Bahn trains are high-speed trains that connect most of the outer suburbs and nearby cities to Cologne and offer direct transport to the airport. Trams in Cologne are unique in that they operate below and above ground, so certain tram stops are at street level while others are similar to a subway station. The trams are ideal for travelling between the different attractions in Cologne as there are multiple stations throughout the city center. Both the trams and trains run at twenty-minute intervals throughout the day and night so visitors can enjoy the nightlife of Cologne without worrying about getting back to their hotel. Buses cover a small portion of the city center but can be an enjoyable way to take in the scenery of Cologne. A KVB ticket is used for all forms of transport in Cologne and these are available as day passes, single tickets, and weekly passes. The KVB tickets can be bought from vending machines at all public transport stations in the city.
The four seasons in Budapest are very different from each other, and each season offers its own unique activities and attractions. Spring is rainy and windy, summers feature extremely hot and humid temperatures, winters are cold, and fall is chilly. Regardless of the time of year you visit, Budapest has festivals galore! The busiest season is summer (June to August), when hotels and attractions are packed. However, this never takes away the city's charm. Experience the Budapest Summer Festival and the Festival of Folk Arts for authentic cultural practices. Fall (September to November) in Budapest is a wet season characterized by chilly nights and warm, sunny days. Take amazing photos at the Budapest Design Week, sample the wine at the Budapest Wine Festival or down a pint of your favorite beer at Oktoberfest. Like the fall season, spring (March to May) in Budapest is a shoulder season ideal for travellers as the summer crowds will have left the city. Since this is the rainy season, be sure to pack an umbrella to enjoy outdoor events such as the Rosalia Festival and the Budapest Spring Festival. Winter in Budapest can be extremely cold, but the snow covered landscapes and buildings adorned with Christmas lights magnificently accentuate the city's skyline.
