Whether you are walking, biking, driving, or riding the beaach trolley, you'll want to pay attention to the tropical fish Mile Markers (and ½ Mile Markers). The Fish Mile Markers start at the South end of Pass A Grille (the Southern tip of St .Pete Beach) with Mile Marker Zero and continue North along Pass A Grille Way, Gulf Blvd., Blind Pass Rd, over the Blind Pass Bridge, then North on Gulf Blvd. through Treasure Island, Madeira Beach, Redington Beach, Redington Shore, Indian Shores, Indian Rocks Beach, Belleair Shores, Belleair Beach, Sand Key and across the Clearwater Pass Bridge to Clearwater Beach. At the bottom of the Pass bridge the markers continue to be visible along South Gulfview Blvd. Go through the "round about" and continue North on Mandalay in Clearwater Beach for about 2 more miles where Mile Marker 25 marks the end of the Fish Mile Markers.
