The Széchenyi Chain Bridge is an iconic suspension bridge connecting Buda and Pest, the western and eastern sides of Budapest. It's best visited on foot to fully appreciate its stunning views of the Danube River and nearby landmarks, like Buda Castle and the Hungarian Parliament Building. The bridge is a public structure, so crossing it is free of charge and can be done at any time, although it's particularly beautiful when illuminated at night. While visiting, expect to spend about 30 minutes walking across and enjoying the views; a stop does not require a guided tour. However, combining the visit with a city tour that includes historical context could enhance the experience. The bridge is accessible year-round, though the winter months can be chilly, so dress warmly if visiting in those seasons. Overall, the Széchenyi Chain Bridge is a must-see for anyone exploring Budapest.
