I'll be Devils Advocate in the kitchen.
If it's a bridge across that stream beyond the slabs, fair play. It's a dodgy pitch with young kids when it's icy or wet. If I ever was unable to walk, then it would be nice to be pushed around Llyn Idwal as a memory of being able to get out in the hills.
For the lucky that still could walk, then it's only a mile of endurance of others that can't walk before they can't proceed further and you get to go up the kitchen, whilst they are pushed down and around the tarn/
People take their mobility for granted. Until they don't have it. Enjoy every step.
