Alabama is a beautiful state. And my home.
Northern and Central Alabama will be very hilly with lots of woods and forests. There are some beautiful valleys along the rivers.
The land will start to flatten out south of Birmingham around Tuscaloosa (on I-59) and Prattville/Montgomery (on I-65). The southern plains can be real pretty too (I've always preferred the hilly areas to the flat land). And then there's the Gulf Coast (a lot people consider the panhandle of Florida to be more a part of Alabama).
If you like a view you can drive out on Shades Mountain in Birmingham (Shades Crest Road) and there are some very nice views of the valley below.
If you are up around Ft. Payne and Mentone Alabama there are some really beautiful mountains and vistas looking out over the valleys. They also have some cabins in Mentone you can rent. Some have a back porch that looks off the side of a cliff and has hot tubs on them. I always thought it would be a blast to rent a cabin up there and take a special lady there for a weekend of....
Don't let anyone talk you into going to UCLA (Upper Corner of Lower Alabama).
Hope you enjoy your visit to Birmingham.
