The Dunedin Causeway crosses shallow grass flats between Dunedin and Honeymoon Island, with roadside parking, easy wading, and fishable water on both sides. It is one of the most beginner-friendly land-based spots in Pinellas County.
The flats here are shallow, so tide height matters as much as tide direction — a strong incoming tide floods the grass and brings fish up onto it.
Best tides
- Incoming tide through the first hours of high tide floods the grass flats and is the classic window.
- The last of the outgoing pulls bait off the flats into the channel edges near the bridges — worth fishing before dead low.
- Very low tides expose much of the flat; use them to scout potholes and cuts you can fish when the water returns.
Best time of day
- Dawn through mid-morning is the prime window — calm water, active fish, and light boat traffic on the flats.
- A dusk high tide fishes nearly as well, especially for snook along the mangrove edges in summer.
- Bright midday sun pushes fish off the shallow grass; slow down and work the deeper potholes and channel edges.
Wind strategy
- The causeway runs roughly east–west, so you can usually find a protected side in a north or south wind.
- A light onshore chop helps the bite on the flats; glassy-calm midday water makes fish spooky — go early.
- In strong west wind, fish the east (St. Joseph Sound) side or tuck near the bridge for cleaner water.
Common species
- Spotted seatrout over grass and potholes year-round
- Redfish tailing on flooded grass, especially fall
- Snook along mangrove edges and bridge shadow lines in the warm months
- Flounder on sandy cuts and channel edges
- Ladyfish, jacks, and mackerel passing through with bait schools
Recommended lures & bait
- Live shrimp under a popping cork — the default rig on these flats
- Soft plastic paddletails or jerk shads on 1/8–1/4 oz jig heads worked over grass
- Topwater plugs at first light on high water
- Cut pinfish or ladyfish soaked in cuts for redfish
Safety & access notes
- Free roadside parking along the causeway; kayak and wade access is easy from the sand shoulders.
- Wear wading boots — scattered oysters and stingrays share the flat; do the stingray shuffle.
- Boat and jet-ski traffic uses the channel near the drawbridge; stay clear when wading.
