Indian Key Fill Fishing

Indian Key Fill is a roadside causeway between two of Islamorada's best-known channels, a spot for anglers who like to fish from the rocks with the tide pouring past. There is no fishing pier here, but the shoreline beside the bridge ends puts you within casting range of fast, deep water.

• Close to the famous Islamorada tarpon channels
• Barracuda, jacks and snapper in the current; snook in the shadows at night
• A small public launch on the fill, listed as temporarily closed for repairs in 2026
• Beautiful views to Indian Key and Lignumvitae Key

The fill carries US-1 across open water at about mile marker 78 in Islamorada, between Upper and Lower Matecumbe Keys.

• The fishing is from the rocky shoreline of the fill, especially beside the ends of the Indian Key Channel and Tea Table Channel bridges
• Parking: informal roadside parking along the fill; pull fully off the highway
• The US-1 bridges have no fishing catwalk; fish from the shoreline, not the bridges
• Hours: none are posted for the highway right-of-way, but the Overseas Heritage Trail path along the fill is listed by Florida State Parks as open 8 a.m. to sunset
• Indian Key Historic State Park, just offshore, is reached by boat or kayak

This is fast-water, mixed-bag fishing.

• Spring (Mar–May): tarpon move through the channels at night; ladyfish and jacks in the current; barracuda on the flats edges
• Summer (Jun–Aug): mangrove snapper along the rocks; snook in the shadow lines at night; bonnetheads and nurse sharks
• Fall (Sep–Nov): jacks and runners chase bait schools; snook remain; snapper still biting
• Winter (Dec–Feb): cooler, clearer water; barracuda and jacks; the odd bonefish on the flats either side

Keep it simple and mobile.

• Lures: 1/4 to 1/2 oz bucktails, soft-plastic swimbaits and topwater plugs for jacks, ladyfish, barracuda and snook
• Bottom: a knocker rig with 1 to 2 oz of lead, 20 to 30 lb fluorocarbon and a 1/0 to 2/0 circle hook with live shrimp for snapper
• Snook: a live shrimp or pilchard free-lined along the bridge shadow line at night, on 30 lb leader
• Tarpon: heavy spinning tackle and a live mullet or crab; landing one from the rocks is tough, so plan a release
• A long-handled net helps from the riprap

The channels either side of the fill carry water between Florida Bay (small, mixed tides) and the Atlantic (two tides a day), and the current runs hard mid-tide.

• Fish the middle hours of the tide, casting up-current and working lures back with the flow
• Dawn and dusk are prime; night tides in spring bring tarpon
• The last of the falling tide is best for snook along the shadow lines
• Wind against tide chops up the channel; calm evenings fish best

This is a roadside spot with real hazards.

• US-1 traffic is fast and close: park fully off the road, keep children close and never cast across or near the highway
• The riprap is uneven and slippery; wear solid shoes and do not climb on bridge structures
• The channel current is strong enough to sweep away a swimmer; do not wade into it
• Watch out for kayaks and boats in the channels
• Not wheelchair-accessible beyond the pull-offs

There are essentially no facilities on the fill.

• Parking: informal roadside pull-offs
• A small public launch on the fill, listed by the FWC as temporarily closed for repairs
• Restrooms, bait and food: none; Islamorada's shops are a few minutes away
• No water; bring drinks, and a headlamp for an evening session
• Once it reopens, the launch is handy for kayak anglers who want to paddle the channel edges or out toward Indian Key on calm days

• Walk the shoreline to find where the current forms an eddy behind the bridge footings; fish stack up there
• Topwater plugs early in the morning can draw explosive barracuda and jack strikes
• For snook, fish quietly along the bridge shadow line after dark on a falling tide
• Pick up live shrimp in Islamorada on the way in
• Indian Key's historic ruins are a short paddle away on calm days, once the launch reopens
• Never leave line on the rocks; wading birds and turtles get tangled

The fill is part of the US-1 right of way in the Village of Islamorada; Indian Key and Lignumvitae Key offshore are Florida State Parks sites with their own rules. Fish from the shoreline, not the US-1 bridges, and obey any posted signs.

• A Florida saltwater fishing license is required unless you are exempt
• Snook, tarpon and goliath grouper have their own rules and seasons — check FWC
• Shore-based shark fishing needs a free FWC shore-based shark fishing permit
• The area lies within the Florida Keys National Marine Sanctuary; check sanctuary zones before fishing
• Check current FWC rules for size, bag and season limits before keeping anything
