Dorian’s night time hike was a fantastic and unique experience! We were very lucky with clear skies and so saw a beautiful sunset and had a great star show at the top of Pen Y Fan. Dorian and Marie were very friendly and knowledgeable about the Brecon Beacons and happy to share their insights and passion for the area. Highly recommended!


Such a fab day. Weather was very kind to us. Dorian was super guide and made the day special. We felt very safe in his hands with his knowledge of the Brecon Beacons. We would definitely use Dorian again and would definitely recommend
