The Bio Lab Road at Merritt Island Wildlife Refuge is one way 6-mile dirt road is located of off SR 3 (Kennedy Parkway) just north of the Scrub Ridge Trail. There is a boat ramp at Bio Lab Road that provides assess to Mosquito Lagoon. For more information visit the Merritt Island Wildlife Refuge at https://www.fws.gov/refuge/Merritt_Island/visit/plan_your_visit.html. The southern end dumps you out at Canaveral National Seashore near Playalinda Beach.
Bio lab is great for boating, fishing or suggest to view wildlife. There is a fee to visit the Bio Lab and you can pay at the Merritt Islando Wildlife Refuge Visitor Center or pay at the kiosk. I have visited Bio Lab road several times now, not for boating or fishing but to see wildlife. I have seen lots of birds and alligators. Here are some of the pictures I have taken.
Remember: Take nothing but pictures, kill nothing but time, leave nothing but footprints
