Is rock climbing hard for beginners?

Rock climbing is relatively easy for beginners since the beginner routes are usually not complex, and actually resemble climbing a ladder. As the grades go up, so does the complexity and the difficulty of the routes.

Beginner rock climbers can usually climb a few grades up from the easiest one, even if it's their first time climbing. For example, one grading system for bouldering is v0, v1, v2... As you go up in the number, the climbing gets harder, new holds are introduced that are harder to grip and use, climbing moves become bigger and more difficult, and the route itself becomes more complex.

Many times, beginner rock climbers and even those who it's their first time climbing can climb between v0 and v3. Some can even go up to v4 and v5, though, this depends on the climbing gym, and the climber. If the climber is in good shape and has prior experience in sports that could contribute to climbing, they could very quickly go up to climbing harder routes.

As you go up the grades, the difficulty between each grade also goes up.
