Walking can be a convenient way to explore Saint Petersburg, particularly in its downtown area, which features a pedestrian-friendly layout with sidewalks, crosswalks, and accessible paths. The city has invested in infrastructure like recreational trails and walkways, making it easier to navigate on foot. However, the subtropical climate can bring high temperatures and humidity, especially in summer, which may make walking less comfortable during certain times of the day. Additionally, while many attractions and amenities are within walking distance in central areas, longer distances between neighborhoods may require alternative transportation.

Biking is another practical way to get around Saint Petersburg, thanks to its network of bike lanes, routes, and recreational trails. The city features paths like the CityTrails system, which connects various neighborhoods and destinations. The relatively flat terrain supports easy cycling, though distances between some areas may require planning. Biking conditions can be influenced by weather, particularly during warmer months, so hydration and sun protection are important.

聖彼得堡的公共交通選擇包括巴士和無軌電車，當中有如 SunRunner 巴士快速交通等服務，連接市中心與其他地區。巴士遍佈全市，是前往多個目的地的實用方式，但部分路線因行車時間較長，可能需要預先規劃。無軌電車如 Downtown Looper，則方便前往市中心的熱門景點。城市基建支援這些交通方式，但由於氣候溫暖及部分地點之間距離較遠，某些行程選擇其他交通工具可能會更合適。

Ferries, such as the Cross Bay Ferry, provide a scenic and efficient way to travel between downtown Saint Petersburg and downtown Tampa. These ferries are pedestrian and bike-friendly, but they do not accommodate cars. Sailings typically operate multiple times a day, with travel times averaging around 50 minutes each way. The ferry docks are conveniently located near key attractions, making it easy to explore the area. However, weather conditions and seasonal schedules may impact availability, so planning ahead is recommended. Ferries are a pleasant option for avoiding road traffic while enjoying waterfront views.
