Granted, Texas has some beautiful scenery, but sometimes we just want to see some honest-to-goodness forest and mountains. And so we head to southeastern Oklahoma, to the edge of the Ouachita National Forest. The terrain is beautiful, with mountain lakes and rivers and thousands of conifers (though you may need a four-wheel-drive in some areas). For camping, head to Beavers Bend State Park (about 3.5 hours from Dallas) or for a less rustic romantic or family outing, pick any of the log cabins and cottages for rent along Highway 259.
