Arad can be somewhat walkable for travelers, especially if you're staying near the city center. The town is relatively compact in this area, with many attractions, dining options, and accommodations within easy reach on foot. However, the city historically prioritized cars, which means that as you move further from the center, the pedestrian infrastructure might not be as developed. Some areas may require the use of public transport or taxis, as they are not as accessible by foot.

Public transit in Arad is quite efficient, making it a convenient option for travelers. The city boasts an extensive tram system, regarded as the second-largest in Romania after Bucharest, which is a highlight of the area's transportation network. The trams, along with a network of buses, ensure that you can cover most parts of the city with ease, even into the night. Tickets are easily purchased, making public transport a reliable and accessible choice for exploring the city.

Arad is fairly bike-friendly, as it has made significant efforts in establishing a robust cycling infrastructure, which is among the longest urban networks in Romania. Biking is a popular way for locals to get around, supported by numerous bike lanes. However, there are some gaps in this network, especially when considering the total extent of roadways, which can sometimes make biking less convenient in certain areas. Overall, cycling in Arad is a reasonable and enjoyable way to see the city, especially in the well-serviced parts.
