Climbing without a safety rope (often called "free climbing" or "unprotected climbing") brings many unique challenges and fun, here are some of the main ones: ### Challenges 1. **Psychological pressure**: No safety rope means that climbers may face serious injuries or danger if they fall from a certain height. This high psychological pressure requires climbers to have strong psychological qualities. 2. **Higher technical requirements**: In unprotected climbing, climbers must have a higher level of technical skills to cope with the complex conditions of various rock walls and improve their climbing skills and judgment. 3. **Physical fitness**: Free climbing requires greater physical strength, endurance and flexibility, and requires concentration when physical energy is consumed to avoid mistakes. 4. **Risk assessment**: Climbers need to quickly judge and assess the risks of each step, including holding points, footsteps and climbing routes. This requires climbers to have rich experience and intuition. 5. **Fear of heights**: For some people, overcoming the fear of heights is an important challenge that takes time and effort. ### Fun 1. **Sense of accomplishment**: Successfully climbing a section of unprotected rock usually brings a strong sense of accomplishment, which can enhance self-confidence and satisfaction. 2. **Close contact with nature**: Unprotected rock climbing usually makes people closer to the natural environment, able to feel the power and beauty of nature, and enhance the sense of connection with the environment. 3. **Extreme experience**: The passion for pursuing extremes and challenging oneself makes free climbing full of adventurous fun, and climbers often enjoy this high degree of challenge. 4. **Improved concentration**: Without safety ropes, climbers are more focused, which may bring a "flow" experience and enjoy the feeling of being fully focused. 5. **Unique journey**: Unprotected rock climbing often means unique adventure experiences and story sharing. The experiences and challenges of climbers together can enhance the friendship between each other. In general, the challenges and fun of climbing without safety ropes complement each other and can provide climbers with a unique experience. Whether it is challenging the limits or enjoying nature, this method can bring a profound experience.
