Walking in Williamsport can be a practical way to explore certain areas, particularly downtown and nearby attractions. The city features a network of sidewalks and trails, such as the River Walk, which provides scenic routes along the Susquehanna River. However, the feasibility of walking depends on your destination, as some areas may be spread out or less pedestrian-friendly. Seasonal weather, including cold winters and hot summers, may also influence comfort while walking. Overall, walking is a reasonable option for shorter distances or leisure, but planning ahead is recommended for longer trips.

Cycling in Williamsport is another practical way to get around, especially for shorter distances. The city features some paved trails, such as the Lycoming Creek Bikeway, which connects Hepburnville and Williamsport over 5.3 miles, offering a safe and scenic route for cyclists. However, bike lanes are limited in many areas, which may require sharing the road with vehicles. The relatively compact layout of the city makes it easier to access key locations by bike, though riders should be mindful of traffic and follow local safety laws.

Public transit in Williamsport is primarily served by the River Valley Transit Authority, which operates bus routes throughout the city and surrounding areas. The system includes fixed-route buses with designated stops, making it a convenient option for reaching many local destinations. The infrastructure supports accessibility for seniors and individuals with disabilities. While buses provide an affordable way to travel, the effectiveness of public transit may depend on the proximity of stops to your destination and the frequency of service. Weather conditions, such as snow or rain, could occasionally impact travel times or comfort when waiting at stops.
