Join the Access Fund, the Arkansas Climbers Coalition, Dynamic Earth and The Little Rock Climbing Center for a day of trail building, erosion control and fun at one of Arkansas' most popular climbing destinations. The North 40 @ HCR has something for everyone. Now it's our turn to take care of our playground. Meet at the campground pavilion at 9 a.m. Dinner, slide show, and more after the work is done. Free climbing and camping for all of the volunteers.
