South of the Border Area is a climbing area in Idaho managed by the State Department of Land, sitting about 0.1 mile from the T & L Area, Rural Wall and Le Petite Covette. The cluster of climbing spots makes it easy to string together several routes in one outing. The climbing here is all sport, with 27 routes spread across the area. Grades run from 5.8 up to 5.13b/c, so there is something for climbers of all levels. Fiesta is the easiest at 5.8, and Teguilla Sunrise is the hardest at 5.13b/c. Summer is the warmest time to climb. Typical averages from a nearby weather station at Massacre Rocks State Park show July highs around 89°F with lows near 53°F, while September cools to highs around 77°F. For a change from the rock, the River Trail and Pohogwe Trail are both within a mile. Pipeline Campground, about 7 miles away, offers a place to stay.
