This video from Florida is called Anna Maria Island‘s Breath Taking Bay Walk At Leffis Key.
From the Bradenton Herald in the USA:
Leffis Key is a natural island paradise
Published: August 4, 2012
Leffis Key is an island preserve due east of Coquina Beach at the southern tip of Anna Maria Island. Once a barren spoil island, the area is a small paradise of native plants, saltwater wetlands and wildlife.
A 26-foot tall hill in the center of Leffis Key offers a 360-degree view of the Gulf of Mexico, Sarasota Bay and the Intracoastal Waterway. The hill is covered with many types of native foliage, such as sea oats, beach elder, dune sunflowers, southern red cedars, green buttonwood, sea grapes, gumbo-limbo and strangler figs.
Leffis Key is a favorite location for bird watching. Each year birders gather at the park for the Manatee County Audubon Societ[y]‘s Christmas Bird Count.
Amenities at Leffis Key include footpaths that weave through the island, up the hill and across boardwalks that cut through dense mangrove forests, opening up to scenic views of the water.
Interpretive signs are placed along the way to provide a better understanding of the habitats, as well as the animal and plant life. There are benches along the path for those adventurers that want to pause and reflect.
Leffis Key offers hiking, fishing, scenic views and an opportunity to learn about our pristine and fragile environment.
Due to the park being in the Coquina Beach Baywalk, dogs are not permitted.
Leffis Key is at 2351 Gulf of Mexico Drive on Anna Maria Island.
