I spend too much time in Budapest and that can be a good thing and sometimes a bad thing when it comes to providing advice. Good, because I know my way around; bad because having done all the “first time” tourist things (multiple times) it can be years since I did something, and things do change. So here is my perception on a subject, I am interested in new perceptions; lets see where i am off base. This subject is interesting because out of habit for the past two decades I have arrived in town, picked up my 30 day TravelCard and only walked to the spots in-between the metro stops. [i added this because somehow I gave Derek the wrong impression]
A nice full day tour of half of Pest might be: Deak Ferenc ter (sort of ground zero for Pest) to Great Synagogue to Great Market Hall to Danube Corso to Parliament Building to Heroes’ Square to Opera House to St. Stephen’s Basilica to Deak Ferenc ter.
Walking that, depending on the route you choose, will take 2.5 to 3.5 hours and cover 12km to 15km (7.5 to 9 miles). Cost = Free.
The trams with big windows and frequent stops are like HOHO busses; and if you buy a TravelCard or a Budapest Card you can hop on and off as your heart desires. Even the one subway line you might want to take is both historic and anything but intimidating.
Using 2 or 3 trams and the M1 metro transportation depending on the route you take will take about 1.5 to 2 hours including about 40 to 60 minutes of walking (3.5 to 4.5 km or 2 to 3 miles). Cost = If you don’t hop on and off, and if you pay by individual tickets, figure 8 tickets at 350 each = 2,800 forints ($8 – very cheap for the day). A 24-hour TravelCard is 1,650 forints ($5) and better a 72-hour card is 4,150 ($12). A 24-hour BudapestCard is 6490 forints ($18) but you should go to the website for it and see if the other benefits it comes with are worth it to you.
To be honest I would add about 20 minutes of walking and get off and then back on the M1 at every other stop to see Andrassy ut.
Part of the charm for me has always been getting off the well-traveled path. So, if you do utilize the metro, don’t let it control your movements; if you pass a side street that has something of interest on it, get off at the next stop and explore. I guess this is the one drawback of the metro, it is too easy to become complacent and just end up going from point A to point B and miss so much in the process. But most people only spend 3 days in Budapest and its soooooo large a tourist area and every bit of it is an amazingly preserved, living, functioning relic built between 1860 and 1940 (more or less).
So recent experiences? What worked for you? Why?
