Treasure Island offers a pedestrian-friendly environment, particularly along its scenic beach trail, which provides easy access to the coastline and nearby amenities. Many areas of the island are compact, making it convenient to reach restaurants, shops, and attractions on foot. However, the tropical climate can bring high temperatures and humidity, especially in summer, which may make walking less comfortable during certain times of the day. Sidewalks and pathways are generally well-maintained, supporting safe pedestrian travel. While walking is a practical option for short distances, longer trips may require alternative transportation.

Biking is a convenient way to explore the area, thanks to its bike-friendly paths and accessible layout. The area features trails and routes that make it easy to reach popular spots, including beaches and local attractions. While Gulf Boulevard can be busy, there are lighted crosswalks to assist with safe navigation. The flat terrain and scenic views enhance the biking experience, though riders should be mindful of traffic in certain areas.

Public transit options in Treasure Island are limited, and the area is primarily car-dependent. While nearby regions in Pinellas County offer bus services, Treasure Island itself does not have extensive public transportation infrastructure. Walking or biking may be more practical for short distances, as the island is relatively small. However, for those relying on public transit, planning ahead to connect with services in surrounding areas is essential. The warm climate can make walking or biking pleasant, but it may also require preparation for sunny conditions.
