Map of Alabama windsurfing sites. Most well known sites are either in the north on the Tennessee River or in the south along the Gulf Coast. Central Alabama seems lacking in a critical mass of windsurfers and/or suitable locations. There are a number of lakes in Central Alabama but they tend to be narrow. Let us know if, in your explorations, you come across any good places.
Map Key will be arriving shortly.
