Previously known as the Welsh International Climbing Centre, the Summit Centre is where I learnt to climb, and it is a really friendly and well-designed bouldering and climbing facility.
It's located about half an hour's drive from Cardiff in The Parc Taff Bargoed area, and the climbing wall features 400+ routes over an impressive 20,000 square feet of surface. There are 8 metre overhangs, Grades between 4a and 9a, both top roped routes (better for beginners) and lead routes (for more advanced), a self-belay device (enabling people to climb without a partner), smaller children's walls, and a dedicated bouldering room. The instructors I've learnt with have been really encouraging, friendly and good fun. All the staff there seem to love their jobs, too.
The centre also offers 3-star bunkhouse accommodation for groups (although living in Cardiff I've never stayed overnight) and offers other adventure pursuits both on site and in the surrounding countryside - including gorge walking, kayaking, high ropes, canyoning, abseiling and caving. read more
