United in 1873, Budapest is ideal for walking. And exploring the city on foot is the best way to burn off all the calories from the delicious food and wine you'll be enjoying. Afterwards, there is no more rejuvenating way to relax than in one of the city's many soothing spas - fed by 80 thermal springs.

Start by strolling along the winding streets on Castle Hill, where the medieval character of Buda has been best preserved. The entire panorama of the two banks of the Danube all the way from Margaret Island - Budapest's green Central Park in the middle of the river - to Gellért Hill and the Castle District has been designated a World Heritage preservation site by UNESCO. At the top of Castle Hill visit the Royal Palace, and be sure to catch sunset at Fisherman's Bastion, with its view of the river, Chain Bridge, Parliament building and Pest spreading out across the horizon.

For a view that takes in sights on both sides of the river, go up Gellért Hill to the Citadel. The hill is home to three famous and historic spas: the Art Nouveau-era Gellért and the 400 year-old Rudas and Rác Baths, the latter two built by the Turks.
