Seb Berthe

Seb Berthe is a Belgian rock climber (born 1993) who appears in a short film that documents an early-season campaign on one of Yosemite’s most demanding big walls. His catalogue entry links him to large-scale trad climbing and to the particular project-phase work that high-end big-wall routes require.

Darkest Before Dawn: A Dawn Wall Story follows Siebe Vanhee’s initial season on the Dawn Wall with Séb Berthe alongside him. The piece is a compact, mostly physical portrait rather than a blow-by-blow chronicle: it conveys fingertip mechanics, minute body positions and the sensory impression of hanging thousands of feet above the valley floor. At roughly nineteen minutes the film privileges feeling and technique — close camera work on hand placement and body tension — over narrative exposition.

What the film shows about Berthe’s climbing is the day-to-day, hands-on side of attempting massive, unknown pitches: how teams probe sequences, manage exposure, and refine tiny moves that determine whether a pitch will go. Viewers get a clear sense of the technical demands and the concrete work of an early-season wall project in Yosemite, rather than a finished-history account of a completed route.
