Boulderwelt Karlsruhe (Karlstraße 14) opened in September 2022 and has transformed a former department store into a 2,000 m² bouldering paradise. The hall is divided into two areas – a family area with children's bouldering (from 2–3 years) and an area for ages 14 and up. Over 200 boulders of all difficulty levels (levels 1–9) invite beginners and advanced climbers alike to climb, with routes being changed three times a week.
An integrated café with a bistro atmosphere, changing rooms, showers, lockers, and climbing shoe rental ensure comfort. The offer is rounded off by training areas (campus board, kilter board, traverses), children's courses, holiday programs, and events for adults, families, and companies.
