Testimonials

I've now been on two courses with The Mountaineering company. Both courses were great, learnt loads and Matt/Sam were brilliant instructors. I would definitely recommend to anyone getting into mountaineering to book onto intro and development courses. I'm looking forward to doing more courses with them in the future. (Google Review)

Alex Heaps

Just the best! From start to finish, this was by far our best experience with a guiding company. We genuinely felt that our goals and objectives were their priority, and the whole experience gave us fantastic preparation and confidence for our next trip to the Alps. A huge thank you to the entire team at TMC — we couldn’t recommend you highly enough!

Chris & Jen

SUPERB Mountaineering Development course. The instructor's energy, enthusiasm and judgement meant we packed in a vast amount. Felt like 6 months progress in 3 days. Thank you TMC.

Dan - Trip Advisor 5*****

I thoroughly recommend Matt as a leader & guide. I experienced an exhilarating & fun day with a super group doing Matt's Ogwen Classics day. Matt managed our mixed levels of ability & confidence with a calm, encouraging, alert & purposeful manner. He inspired confidence through recognition of our efforts & shared his knowledge & experience to support our skill development. The day passed all too quickly!

Ferne Davies

The Introduction to Mountaineering course was exactly what I needed to build confidence in my skills and knowledge. I'm ready and super keen to make the step towards leading scrambles and trad routes.

Had a fantastic weekend with Matt on the mountain skills course - he is really friendly + approachable, and tailored the two days to what we enjoyed + wanted to learn. Would definitely recommend to anyone wanting to build their confidence with mountain hiking + navigation!

Kirsty

I cannot rate these guys highly enough. They provided 3 guides for our Welsh 3000’s attempt along with full support, these guys couldn’t have been nicer. I felt safe and well led throughout, and wouldn’t hesitate to recommend them for your adventures!
