Climbing "Triceraptor" (7-) on the Arnstein Hauptwand is a memorable experience. This route, likely situated in a classic Austrian climbing area, promises a challenging yet rewarding ascent. Given the grade of 7- (French grading scale), expect sustained technical climbing with demanding sequences. The rock on the Arnstein Hauptwand is likely limestone, so anticipate features like pockets, crimps, and possibly some slopers. Success will require solid technique, good footwork, and efficient resting. The sustained nature of a route on a Hauptwand (Main Wall) suggests that fitness and endurance will also play a key role. Reaching the top of "Triceraptor" would be a proud achievement.
