As a die-hard traditional climber, I was really surprised at how much I liked gym climbing once I started doing it in my 50's. I do not do it anymore because my husband quit and the cost of single membership is pretty steep. Most gyms have good family rates. It is just plain fun! And it really does improve your traditional climbing as long as you continue to get in a lot of outdoor climbing too. It was the answer to keeping in climbing shape during rainy winters. Just be sure if you get your daughter into lead climbing that she gets some GOOD training. I am a stickler about wearing a helmet outdoors, even if just top roping. It is easy to strain tendons in gym climbing, so know when to call it a day.
