Walking on Marco Island can be a pleasant way to explore certain areas, especially near the beaches and local attractions. The island features some pedestrian-friendly zones, but its overall layout and infrastructure are not entirely designed for extensive walking. Distances between key locations can be significant, and the subtropical climate often brings high temperatures and humidity, which may make walking less comfortable during certain times of the day. While walking is enjoyable for short distances or leisurely strolls, it may not be the most practical option for getting around the entire island.

Biking is a practical way to explore Marco Island, thanks to its flat terrain and accessible routes. Many roads include bike lanes, making it easier to navigate the island safely. Popular areas, such as parks and beaches, are generally reachable by bicycle, and the compact size of the island minimizes travel distances. However, riders should be mindful of traffic and ensure they follow local biking laws. The warm climate can be favorable for biking, but staying hydrated and avoiding peak midday heat is recommended for comfort and safety.

Public transportation on Marco Island is limited, with services primarily provided by Collier Area Transit (CAT). While buses connect Marco Island to surrounding areas like Naples, the island itself is small and walkable, making public transit less essential for local travel. The infrastructure is more car-oriented, and distances between destinations may not always align conveniently with bus routes. Additionally, the subtropical climate can make waiting for buses outdoors less comfortable. For those relying on public transit, planning ahead is important to ensure schedules and routes meet travel needs.

Ferries on Marco Island are primarily used for accessing nearby destinations like Keewaydin Island and Key West. These services are pedestrian-friendly but do not accommodate cars or bikes. Routes to Key West typically begin boarding early in the morning and operate multiple times a day, with travel times varying based on the destination. Ferries are a convenient option for reaching places only accessible by water, though weather conditions can occasionally impact schedules. The infrastructure supports smooth boarding, but the lack of car transport may require additional planning for those needing vehicles at their destination.
