_ If you want children aged 3 to 4 to experience rock climbing activities and cultivate their interest, you can let them climb ladders at home, or take them to places with climbing wall, such as rock climbing halls, for free, without coaches. Generally, climbing walls that do not need climbing ropes are relatively short, with a height of only 3 or 4 meters, so they are generally called "cordless climbing".
_ From climbing (cordless climbing) to climbing (rope climbing): When children try to climb, they need teachers' guidance and help them finish their teaching. Because if parents don't know rock climbing, it's difficult to operate. At the beginning, there must be professional teachers' guidance, mainly to guide parents how to use equipment, to help parents better understand the sport of rock climbing and learn how to guide their children, instead of teaching them too many skills, so that children feel forced to learn.
