A good climbing gym is judged on its routes and on how safely it is run. Look for a clear briefing on belaying and falls before the first climb, and check that the staff check harnesses and knots. Newer climbers often find it helps to try a few easy routes before booking a longer session, since grip and technique matter more than strength at first. Many regulars bring their own chalk and climbing shoes, and check whether shoe hire is included before arriving. Weekday evenings tend to be quieter than weekends, which suits people who want more time on the wall.
