About Us


Our Story

Mountain yak started life in 2015 after its founder Jethro Withers, noticed a distinct lack of providers of quality mountain holidays and adventures.
We specialise in unique adventure holidays and challenges around the world, with small groups and expert guides. We provide a personal service that you simply don’t get with the big tour operators.

Know how

Lead guides Jethro Withers and Charlotte Dovey have a wealth of experience in travel and the mountains that started in their late teens. Exploring Europe, Scandinavia, and New Zealand in the early 2000s, we soon got the bug for travel and the mountains.

Favourite Tour/Course: “Our Poland Scrambling week has got to be up there, its a great place to visit and the scrambling is so unlike other parts of Europe. Its great to get hands on with the mountains and experience the atmosphere of a technical ridge.”

Favourite Tour/Challenge:

“With so much on offer it’s a hard to choose… but I would go with the Stubai 7 summits challenge. It’s such a unique part of Austria that many people haven’t heard of. Its so rich in culture and the mountains are full of character, offering everything from hiking to winter mountaineering all in one challenge.”

MIC Mountaineering Instructor Certificate





Mountaineering has been Bryn’s life since an early age. Growing up on the northern end of the Snowdonia National Park he soon made good use of his surrounding and built up a wealth of experience in the mountains and on the crags of North Wales. As a teenager Bryn made the decision to work towards being a mountaineering instructor and progressed through the Mountain Training qualification structure to eventually reach the top qualifications called the Mountaineering Instructor Certificate (MIC) and International Mountain Leader (IML).

Bryn has worked full time in the mountaineering sector both privately and freelance since 1998. He has worked for a huge number of organisations and for 8 years was the Executive Office for Mountain Training where he was responsible for managing the qualification system and network of course providers around Wales. Bryn has been running various Mountain Training courses for the last 12 years and has trained and assessed over 400 candidates.

IFMGA Mountain Guide







Paul is Mountain Yak’s go to guy for any high mountain trips, he is a fully qulifed IFMGA Mountain Guide based in the French Alps.

Paul’s heart lies in traditional climbing, especially in his homeland of Ireland, however he is constantly drawn away on all types of adventures to many corners of the earth. Skiing, sport climbing, ice climbing, big wall climbing, and mountain biking, are all high on his list of distractions. His desire to climb became the basis on which he made most of his life decisions and it’s no surprise that climbing and travelling have taken him all over the world.
