The Fred Marquis Pinellas Trail is a linear trial that extends from St. Petersburg through Palm Harbor and other communities and ends in Tarpon Springs. The popular trail was built along an abandoned railroad corridor and is used for walking, jogging, skating and biking. 

The trail provides a natural green space with many shaded areas. Pinellas County Parks and Conservation Resources maintains it.

There are a few "rules of the road" on this trail. Pedestrians and wheelchairs have the right of way. Wheelchairs must use pedestrian lanes. Electric handicap wheelchairs are permitted, however motorized and electric vehicles and bicycles are not. 

Bicyclists are not allowed to wear headphones at any time. Bicyclists under age 16 must wear a helmet. Pets are allowed but must be kept on a 6-foot leash. Horses are not permitted on the trail.

The trail has an Emergency Response System in place. Bright yellow decals are on the trail at 200 foot intervals. They help identify specific locations in case there is an emergency or maintenance problems need to be reported.
