What Is Beta in Climbing?

Beta is any information about how to climb a particular route or boulder problem — which holds to use, the sequence of moves, foot positions, rests, and clever tricks. Climbers share beta in person, in guidebooks, and in videos, and using it changes whether an ascent counts as an onsight, flash, or redpoint.

Why it matters

Beta makes a climb easier by removing the guesswork. It also defines ascent style: an onsight uses none, while a flash uses beta on a clean first try.

Beta etiquette

Offering unsolicited beta — ‘spraying’ — is frowned upon, since many climbers want to unlock the crux themselves. Ask before giving it.

Good to know

When working a project, refining your beta over attempts is a big part of eventually sending.

Frequently asked questions

What does 'beta' mean in climbing?

Beta is the inside information on how to do a climb — the specific holds, the order of moves, where to place your feet, where to rest, and any tricks for the hard sections. Getting beta makes a climb easier because you don't have to figure it out yourself.

Is it rude to give unsolicited beta?

Often, yes. 'Spraying beta' — shouting unsolicited advice at someone working a climb — is widely considered poor etiquette, since many climbers want to solve it themselves. The norm is to offer beta only when asked.

Why does beta matter for onsighting?

Because an onsight requires zero prior information. Any beta you receive — even accidentally overhearing it — turns a potential onsight into a flash at best. That's why climbers aiming to onsight avoid watching others or reading detailed descriptions.
