A cave specialist, Principal Instructor Chris is as happy underground as he is on the surface. However, Chris is equally as expert climbing the cliffs of the Peak District or paddling it’s waterways. With his infectious enthusiasm and his approachable down to earth Yorkshire attitude, you’ll have a memorable and very enjoyable adventurous day out. 

Chris started climbing, caving and boating as a participant over 25 years ago whilst working as a Youth Worker. Having an insanely contagious interest in the outdoors he decided to begin gaining qualifications as an Outdoor Instructor to help share the joy and excitement and enable others to participate in some of the amazing outdoor activities that he enjoys. It seemed pertinent then to promote health and wellbeing through an active outdoor lifestyle.

Climbing craggy gritstone and limestone edges, exploring underground cave and mine systems and networks, negotiating water problems, hillwalking and bushcraft skills are just some of the outdoor activities that Chris enjoys participating in and delivering.
