Where: On a pony trek for two through the magical Smoky Mountains. Arrange for a private picnic against the backdrop of jaw-dropping nature on the trail. If you don't find sore behinds conducive to romance, opt for a horse-drawn carriage ride instead.
Why: Picture mist-wreathed streams, leaf-dappled sunlight and dense forests: Here, nature is at its most romantic.
Where to stay:The impeccable nouveau-farmstead Blackberry Farm, set in pristine Tennessee countryside, will give you one of the warmest welcomes imaginable (and set you up with those horses, carriages, and other proposal paraphernalia).
