Take an early morning bus or train heading to Helsinki to catch the cheapest international options. Check VR or Matkahuolto for train/bus schedules within Finland; they often connect to budget flights or longer-distance buses.
Book a low-cost flight from Helsinki Airport (HEL) to Budapest Ferenc Liszt International Airport (BUD). Check airlines like Wizz Air, Ryanair, or EasyJet for the lowest fares; booking in advance ensures better prices.
Settle into a budget hostel or guesthouse; options include Maverick Hostel or Wombats City Hostel Budapest, which offer affordability and central locations.
Visit St. Stephen’s Basilica (free to enter, small fee for tower) and consider a budget tour of Parliament from outside, as internal tours may require advance booking.
