The climb likely involves a variety of holds and techniques, requiring good footwork and body positioning. Specific details about the rock type, holds, and protection would depend on the location and specific route within the Dvoupatrák climbing area. A thorough guidebook or local beta would be necessary for a successful ascent. Enjoy the climb!
