Budapest is an easy city to navigate; as long as you remember where the River Danube is, you will not get lost. Having taken that into consideration, it is best to begin viewing the city from the banks of the river.
Duna Korzo
This tour is an orientation to the city and its sights; you will start and end in the same spot, making a circular tour of the downtown area. A good place to start is the Duna Korzo on the Pest side. This long, pedestrian-only stretch passes in front of the Marriott Hotel, and continues along to the InterContinental, where it ends at the foot of the Chain Bridge. From anywhere on the Duna Korzo you will be able to enjoy spectacular views of the city: you will be able to see Buda, with its impressive Royal Palace, Gellert Hill and much more. It never fails to take the breath away on first viewing. For a pick me up after your tour, try Karolyi Etterem.
Chain Bridge
Stroll along the Duna Korzo, maybe stopping at a cafe or two. If you want, take one of the green staircases down and hop on any passing No. 2 tram for a faster moving view. Continue by walking across the city's most famous bridge, the Chain Bridge. It was the capital's first, and it affords wonderful views: north to the Parliament, Margaret Island and the distant hills, south to Gellert Hill and the buildings of Pest. The river runs almost directly north-south through the city center, with Pest on the East side and Buda on the West. Stay for a few moments, taking in the scenery and acquainting yourself. At the Buda end of the Chain Bridge you will see the tunnel under Castle Hill, Clark Adam Square, the O kilometer stone and the station where you can catch the Funicular up to the top of Castle Hill. The ride to the top is short, but during it you will get a sweeping and panoramic view of Pest (from where you have just walked). For a nearby bite to eat, try Aranyi Szarvas
Royal Palace
At the top of the funicular you will see the massive Royal Palace to your left (south), while the Old Town attractions begin off to the right (north). You might want to visit one of the museums in the castle, such as the National Library, the Ludwig Museum- Museum of Contemporary Art, the Hungarian National Gallery, and the Budapest History Museum. Not far from here, as you walk north into the Old Town, you will get some of the finest views of the city in the historic Jewish quarters. Further along lies the plague column, a memorial to the countless plague victims who were too numerous to be buried in standard graves. Here you will also find the most photographed church in the city, Matthias Church, backed on the riverside by the fairy tale-like Fisherman's Bastion. Take time to admire the views from the top, once again they are stunning. The Hilton Hotel is worth a look: inside are the remains of an ancient church. You can now catch the Castle Bus from in front of the Hilton down to the last stop, Moszkva ter (Moscow Square). Very near, stop in to Ezustfenyo Etterem for traditional Eastern European fare.
Margaret Island
On Margaret Island there are baths to relax you, grassy fields to nap in and flower-filled sections to enjoy. When you're refreshed, get back on the next tram No. 4 and take it all the way back to the Pest side, getting off at Oktogon. You should remember this place for your next tour. After a quick look around, start walking down Andrassy ut towards the river (about 15 minutes). If you're tired, catch the oldest Metro on the continent and get off at the last stop—Vorosmarty. You will now find yourself in the main cafe square near the river, and at the start of Vaci utca, the famous shopping street. You may want to leave the shopping for another day, and just relax in Gerbeaud, sipping coffee and enjoying one of their world famous cakes or pastries. Walk another 100 meters west (towards the river) and you will be right back where you started; having completed a circle of the main sights, you are now well oriented and ready for more touring; but leave that until tomorrow!
Vaci utca
Now that you have your bearings and understand the layout of Budapest, it's time to visit some of the more famous sights. This second tour begins right where you started and ended your first tour; along the Duna Korzo, or Embankment. From the Duna Korzo, walk back to Vorosmarty ter going away from the river. To the right is Vaci utca, the city's most famous shopping street. Walk along Vaci utca, at your leisure - you will see some wonderful architecture as well as have a wide choice of interesting shops to peruse. You may also want to explore some of the streets that lead off to the East and West; like Vaci utca, they are also pedestrian only. Eventually you will come to what appears to be the end of the street, where the cars whizz by to get onto the white Erzsebet Bridge. Take the pedestrian underpass and you will come up on the other side of the street (while underground, take time out to look at the photos of Budapest over the years which can be seen behind glass on the underground passage walls). On this side of Vaci utca, (technically the southern side), keep your eyes raised upwards, especially when you come to the intersections, where you will see the bullet and shrapnel holes in the building façades, painful testament to the grim events of 1956. When you get to the end of this section of the street, you will be facing one of the city's many interesting Covered Markets. This one is especially popular with tourists, as much of the upper floor is devoted to Hungarian handicrafts and souvenirs. Take the time to find the langos (fried dough) booth, or have a glass of wine with the many locals who do their shopping at the food stalls on the ground floor.
Gellert Hill
Exit the market hall from the same doors you entered, and walk towards the river. Ahead, you will see the beautiful green Iron Bridge. This leads to Gellert Hill, and the famous
Underground Railway Museum
When you're ready, take the metro to Deak ter. While changing lines, stop in at the Underground Railway Museum and learn a little about the history of the continent's oldest metro line. Continue along on line 1, and take it all the way to Heroes' Square (Hosok tere). This picturesque and ceremonial square has been built on a grand scale. The monuments here are impressive (there used to be a statue of Stalin here in 1956), and behind the square lies City Park, the Zoo, the Amusement Park and the world famous Gundel restaurant. On both sides of the square are huge museums. All in all it would not be difficult to spend several days just exploring the nearby attractions.
Opera House
When you're finished with the square, take the time to walk down Andrassy ut, admiring the many fine houses and buildings. Along the way you will come across the Opera House, Liszt Square and many other interesting sights. If you're tired, stop in for a bite to eat at Demmer's Teahaz, or take the metro back to Vorosmarty square: you will be right back where you started, and ready for a stop at a cafe or a rest by the river.
Anyway you see the Danube and its surroundings will leave you with scenic views and pleasant memories of Budapest.
