Sender One has all types of climbing. It is great for bouldering, top roping, lead climbing and occasionally there is even a speed climbing wall set up. The bouldering area has many different angles including walls that are just barely vertical, completely overhanging and everything in between. The climbing walls are about 60ft tall making them the tallest in LA County and creating an excellent environment for top roping and lead climbing. In addition, there are multiple campus walls, a moon board, and multiple hangboards with hooks and weights to train with weight. All the walls are constructed with Walltopia panels and are very high quality so all surfaces are rough and let you smear on the walls. All routes are marked by holds of a single color with the start hold marked with a single tag stating the name, color, grade, date it was set and the initials of the setter. All the holds are very high quality, and routes are switched out on a weekly basis. Each individual route may remain on the wall for up to 4-8 weeks depending on different events happening at the gym. The floors in the bouldering area are 12” padding with continuous rubber cover. It is very nice to fall on, but dusty. The flooring in the climbing area is soft, but not something you would want to fall on from more than 5ft up the wall.
