An indoor rock-climbing wall recently opened in Hoboken—the first in Hudson County. Bouldering as it’s known is when a person climbs on short walls without the help of ropes. Thick protective padding; climbing shoes (for rent); gloves; and climbing chalk help prevent injuries. The wall features 600 square feet of slabs, overhangs, and transitions that ensure a person of any skill level will be challenged. The benefits are plentiful, helping build strength, flexibility, endurance, and balance. The wall, which was completed at the end of summer, is located at 35-Minute Bootcamps. There is a modest entrance fee. It is open daily seven days a week and until 11 p.m. on weekends. Beginner, advanced, and safety classes are offered.
