Hopelands Gardens is right in the city of Aiken! It's beautiful and free to the public. There is a horse museum right there next to it, that is pretty interesting as well, even if you're not really a horse person :)
We've never been, but it's on our bucket list! Enjoy a date night out on the town the night before the wedding. Have a good meal and then head out to experience Aiken's night life!
