Collier-Seminole State Park Fishing

Collier-Seminole State Park puts you on the Blackwater River, a brackish tidal river running through one of the largest mangrove swamps in the world, with a boat basin seawall that the park lists as an accessible place to fish.

• Level, easy fishing from the boat basin seawall
• Snook, mangrove snapper and redfish along the mangrove edges
• Winter sheepshead and black drum; summer jacks, ladyfish and small tarpon
• A quiet state park with a campground, picnic pavilions and kayak rentals
• Wildlife all around: manatees, alligators, crocodiles and wading birds

The park is on the Tamiami Trail (US 41) southeast of Naples, on the way to Everglades City; the boat basin sits inside the park beside the picnic area.

• Hours: 8 a.m. to sunset, every day of the year
• Entrance fee (September 2026): $5 per vehicle with two to eight people, $4 for a single-occupant vehicle
• Since June 2026 the ranger station has been open only Friday to Sunday, 8 a.m. to 5 p.m.; the park does not say how the fee is paid on the other days, so follow the instructions posted at the entrance
• Parking at the picnic area next to the basin
• Surface: a level seawall and paved park roads
• Paddlers can launch at the basin and follow the river to Blackwater Bay

The Blackwater River is a mix of salt and fresh water, so the basin holds brackish backcountry fish rather than surf species.

• Spring (Mar-May): snook and redfish feed along the mangroves as the water warms; sheepshead linger early in the season
• Summer (Jun-Aug): mangrove snapper along the seawall, snook at dawn and dusk, jacks, ladyfish and small tarpon rolling in the river
• Fall (Sep-Nov): redfish and snook feed hard ahead of winter; snapper stay on
• Winter (Dec-Feb): sheepshead and black drum on the bottom; snook push up the river on cold snaps and hold in deeper water

Light to medium spinning tackle with 10 to 20 lb braid covers most of what swims past the seawall.

• Live shrimp on a 1/0 circle hook with 20 to 30 lb fluorocarbon leader, free-lined or under a popping cork along the mangroves
• Mangrove snapper: small pieces of shrimp or cut bait on a light knocker rig close to the wall
• Snook and redfish: a small pinfish or pilchard, or a paddle-tail soft plastic worked along the edges
• Sheepshead and black drum in winter: shrimp or fiddler crabs on the bottom
• A long-handled landing net helps you lift fish up to the wall

Tides here are mixed, usually two uneven highs and lows a day with a small range, and the river runs noticeably on the stronger tides.

• Fish the moving tide; the first half of the outgoing pulls bait out of the mangroves
• The park warns that parts of the river are shallow at low tide
• Dawn and dusk are best for snook, especially in the summer heat
• Heavy summer rain darkens and freshens the river; the higher tides fish better after a downpour
• Winter cold fronts drop the water and slow the bite, so fish the warmest part of the day

The basin seawall is level and close to the parking, and the park lists fishing there among its accessible amenities.

• American alligators and American crocodiles live in the park: keep back from the edge, never feed wildlife and never leave fish scraps behind
• Keep clear of boats using the ramp and paddlers at the canoe launch
• Mosquitoes and no-see-ums are fierce at dawn and dusk and through the wet season
• Summer afternoons bring lightning; leave at the first thunder
• Manatees use the river; give them room
• Heat and sun are serious here, so bring water and shade

The park's day-use area sits right beside the boat basin.

• Restrooms at the picnic area
• Two picnic pavilions with tables and standing charcoal grills, first come, first served
• A playground by the basin
• Boat ramp and canoe and kayak launch into the Blackwater River
• Kayak and paddleboard rentals through the park's concession
• A 105-site campground with hot showers
• No bait or tackle shop was confirmed in the park, so bring bait and everything else you need
• The Blockhouse and the Royal Palm Hammock Nature Trail were closed in 2026

• Check the park's alerts before you drive out; several buildings and trails had temporary closures in 2026
• The ranger station has tide information and river maps when it is open
• Rent a kayak from the concession to reach the mangrove points downriver toward Blackwater Bay
• Carry insect repellent in every season
• Arrive at opening in summer for the cooler, quieter first hours
• Take a look at the Bay City Walking Dredge, the machine that built the Tamiami Trail, on your way in

Collier-Seminole State Park is run by Florida State Parks, part of the Florida Department of Environmental Protection.

• Open 8 a.m. to sunset; a per-vehicle entrance fee applies
• The park reminds anglers that all fishing must follow state rules on size, number, method of capture and season
• A Florida saltwater fishing license is required to fish for snook, redfish and other saltwater species unless you are exempt
• Alcohol is prohibited in the picnic area
• Pets must be kept on a leash no longer than 6 feet
• Snook and tarpon have their own rules: check FWC
• Check current FWC rules for size, bag and season limits before keeping anything
