Started at parking lot. First part of Trail is along the beach but after the first fort, it turns into a nice gravel/dirt path that takes you all the way to the main batteries. Flat all the way, a bit windy along the shoreline. Public bathrooms available along hike. Great hike!
V L. on Blackbird Marsh Trail
Flat coastal trail. Lots of very interesting birds (including raptors). Getting there, you walk along part of the Florida National Scenic Trail. Can easily walk to the water as well. Take a tour of Fort Pickens at Gulf Islands National Seashore - the history lesson is very neat.
