Charleston climbers are a stubborn lot.
In spite of being three hours away from the nearest sport and traditional climbing routes, they have proudly made their own climbing structures like Coastal Climbing, and The James Island County Park Wall to feed their climbing appetites during the week. Coastal Climbing offers a great gym where you can stay in shape, and where you're free to climb with friends in a relaxed environment. There are hundreds of problems marked throughout the gym, and if you are looking for more of a challenge, just ask one of the staff to create a new problem for you, they are more than willing to do so.
The James Island County Park Wall is another fantastic manmade wall that rises roughly 80 feet in the air. Wall supervisors change up the routes regularly, and can accommodate any level of climber. If anything, these establishments are proof that you cannot keep Charleston climbers down. Literally.
