Budapest, the capital of Hungary, is a city bisected by the Danube River, renowned for its thermal springs, ruin bars, and stunning architecture. Accessibility varies, with some areas being more pedestrian-friendly than others; public transport is generally efficient. Solo exploration is safe and rewarding, but guided tours offer deeper historical insights. The best time to visit is during the shoulder seasons (spring and fall) for pleasant weather and fewer crowds; summer can be hot and crowded, while winter is cold but offers Christmas markets. A budget trip can cost around $50-$100 per day, while a more comfortable experience might range from $150-$300. A typical visit lasts 3-5 days to experience the key attractions like Buda Castle, the Hungarian Parliament Building, and the Szechenyi Thermal Baths. Consider purchasing a Budapest Card for free public transport and discounts on attractions.
