The best way to enjoy Barcelona is by foot or using public transportation. The city has a wide range of transport options, including buses, metro lines, and taxis. Budget around €2.20 for a single trip on bus or subway.
Travel time between popular attractions may vary from 10 to 30 minutes depending on location.
If you have an extra day, consider visiting Montserrat, a mountain monastery located an hour away from Barcelona. You could also add a visit to the Gothic cathedral of Santa Maria del Mar located in the Born district to your Day 1 itinerary.
If you have less time, prioritize your preferences and select the attractions that interest you more. Stay close to the city center to maximize your time.
