We did the PYG pass with just turned 8 year old ds2 and nearly 10 ds1.
Parked at pen y pass, we did get up at stupid o clock to park about 8:30 am. It was a bit of a slog, steep in places and Ds2 took a lot of coaxing along, he struggled at times but he never gave up and I was so incredibly proud of both boys.
We came down the PYG pass too, coming down was easier than I expected.
We all had walking boots and full waterproofs. It was damp when we set off, the sun shone but the time we were halfway back down. Could see no further than the end of our arms at the top but it was great.
The views from the PYG pass are incredible, it's well worth the effort. We took lots of sweets for snacks on the way up and ate in the cafe at the top.
The boys still talk about it and I'd love to do it again.
We do walk a lot now. Doing Snowdon gave them confidence I think that they can do it and we did a 9 mile walk later in that holiday and have done a number of 6-7 mile walks since.
This years holiday will be very walking based, I'm just hoping they don't grow out of it when they hit the teenage years
