Arendal's city center is notably compact, making it a convenient place for travelers to explore on foot. The presence of numerous shops, restaurants, and cultural attractions like museums enrich the walking experience. The historic architecture and picturesque harbor add to the charm, offering a pleasant ambiance for strolls. However, the town's hilly geography and limited coverage of pedestrian-friendly amenities beyond the central area mean that accessing further-flung points of interest or nature spots usually requires transport.

Arendal's public transport system is centered around buses, which effectively connect different parts of the town and link to surrounding areas. This bus network is reliable for local travel and accessible through an easy-to-use online system. While Arendal lacks a metro or dense tram system found in bigger cities, it compensates with bus routes that cover vital regions and interconnect with regional transport systems such as the train line at Nelaug station. The nearby Kristiansand Airport further enhances connectivity with an express coach service to Arendal. However, the number of services and routes could be increased to improve overall coverage.

Arendal provides a fair opportunity for cycling enthusiasts, with trails like "Tungvekteren" offering thrilling experiences for mountain biking. These trails are well-regarded and attract adventurous bikers, enhancing the town's appeal as a biking destination. Additionally, options exist for more relaxed rides along scenic coastal routes. Nonetheless, the city's hilly terrain presents a challenge for everyday biking, and the infrastructure for urban cycling could be further developed to make biking a more convenient option for city exploration.
