Climbing at Greenhill is a challenge suitable for both beginners and experienced climbers, with routes that cater to different ages and abilities.
Participants split into two groups: one climbs while the other learns to belay using friction devices, supporting their teammates from the ground. The session blends practical ropework skills with personal development: Participants will learn to use carabiners and harnesses, in addition to developing their communication, trust, and problem-solving skills.




A climbing session typically involves two groups rotating between climbing and belaying. Climbers choose routes suited to their ability on our indoor or outdoor wall, while belayers manage the rope system under supervision from our instructors.
Wear warm layers in winter and a waterproof layer in wet weather. Clothing should not be bulky, as a harness will be worn over it. Closed-toe shoes — trainers or boots with good grip — are essential. Avoid scarves, loose accessories, and ensure long hair is tied back to prevent entanglement with climbing equipment.
Greenhill provides all climbing equipment, including harnesses and helmets. These must be worn at all times within the designated climbing zone.
Climbing and abseiling take place at the climbing tower on-site at Greenhill YMCA National Centre (BT33 0GR). Indoor routes may also be used depending on weather and group needs.
No prior experience is required. Activities are graded and supervised to ensure accessibility for all ability levels.
Category A activities are the lowest risk and are suited to most ages. Category B and Category C activities involve a higher risk factor and require more initiative. Some of these activities are run off-site, including Annalong, Castlewellan, and the Mourne Mountains.
