We are heading to Rhayader in Wales for May half term with 3 children- 12, 10 & 4. Really looking forward to just being outside, walking, beautiful scenery, etc. Just wondering if anyone knows the area and could recommend somewhere for a proper day out within an hours drive, just to break the week up with something different! Have looked at Folly Farm and Zip World but they are 2 hours away which feels a bit too far considering we are already on holiday!
