Bloc is an indoor bouldering wall run by TNR Outdoors, the Llangollen activity centre at Mile End Mill on Berwyn Road, beside the River Dee. The room has angled panels in red, grey and white with problems for a range of abilities, set by the TNR team, and a padded carpeted floor.
The TNR café is open whenever Bloc is, serving stone-baked pizzas, homemade cakes, sausage rolls, snacks and hot and soft drinks. It closes 30 minutes before the wall.
TNR says kids' clubs, coaching and birthday parties are on the way. There is no monthly or season pass yet.
