Boat Tours, Paddle-craft Rentals and Select Conveniences Temporarily Unavailable
Glass-bottom, snorkel, diving and island boat tours, and rentals for canoes and other paddle-craft, are temporarily unavailable. The park is working to resolve the issue as soon as possible and regrets the inconvenience. Limited snack items are available.
Seagrass meadows are found throughout the park, and are important in providing food and habitat for fish, invertebrates, manatees, and turtles. Seagrasses also help maintain water clarity and cycle nutrients.
Just like the grass in your yard, seagrasses have belowground roots and rhizomes. The seagrass plants use these parts for stability and to exchange nutrients with the soil. Vessel groundings on seagrass shoals can cause serious damage, especially when the roots and rhizomes are destroyed.
Vessel groundings create trenches and "blowholes", and when the soil and plants are excavated, the seagrasses have a hard time growing back. These injuries may take several years to recover! Unfortunately, many shallow shoals in Biscayne National Park are heavily impacted by vessel groundings.
The park's Habitat Restoration Program conducts seagrass restoration at vessel grounding injuries, with the goal of accelerating recovery. Each year, the program tries to restore several grounding sites.
Commonly used restoration methods include filling excavations, applying fertilizer by using bird roosting stakes, and transplanting seagrasses. Restored sites are monitored for a period of several years to track recovery.

Many sea turtles live in the waters of Biscayne National Park and often nest on the park's few sandy beaches. Park employees monitor nesting beaches each summer to protect new nests from raccoons and other predators. More...
