Arcata provides a reasonably walkable environment, especially in its downtown area where a variety of shops and eateries are clustered around Arcata Plaza. This compactness makes it feasible for travelers to navigate the town on foot, particularly if they are staying centrally. The infrastructure supports walking in many areas, with sidewalks and pedestrian-friendly streets enhancing the experience. However, the walkability decreases as you move towards the outskirts of the city, indicating that while central Arcata is excellent for walking, reliance on a car might be necessary in less dense areas.

Arcata's public transport system is modest, centered around the Arcata & Mad River Transit System (A&MRTS), which connects the town with basic bus routes. These routes primarily operate during weekdays, with limited service on Saturdays, emphasizing the need for careful planning if reliant on buses. Additionally, the Arcata Transit Center connects travelers to broader services like Amtrak and Greyhound, but the infrequency and sparse reach of local buses may not meet all needs. For those heavily dependent on public transit, these limitations can present obstacles.

Arcata is quite welcoming to cyclists, with dedicated bike lanes, trails, and a bike share program in partnership with Cal Poly Humboldt. The city's efforts to enhance cycling infrastructure reflect a commitment to becoming even more bike-friendly, making it a viable option for daily commuting and exploration. While some hilly areas and the potential presence of inattentive drivers could pose challenges, the available infrastructure and ongoing improvements position Arcata as a cycle-conducive city, providing a solid bike experience for travelers.
