Budapest

Some of the must-see attractions include the Hungarian Parliament Building, Buda Castle, Fisherman's Bastion, Matthias Church, Széchenyi Thermal Baths, and the Great Market Hall. Don't miss a walk along the Danube, especially at night when the city is beautifully illuminated.

Budapest has an excellent public transportation system, including buses, trams, and the metro. The metro is the fastest way to get around, especially in the city center. Walking is also a great way to explore the city, particularly in the historic districts. Consider purchasing a Budapest Card for unlimited travel and free entry to some attractions.

The best time to visit Budapest is during the shoulder seasons, spring (April-May) and fall (September-October), when the weather is pleasant, and the crowds are smaller. Summer (June-August) is also popular, but it can be hot and crowded. Winter (November-March) offers a different charm with Christmas markets and fewer tourists, but it can be cold.
