A wonderfully wild big adventure with 6 boys aged 5-7.
All the way to the top top (crucially detail - there's a fake top!) powered by 10000 bleaberries each. 
I could say we walked but I imagine if we tracked it we did 5% walking and rolled, crawled, climbed, slid and ran the rest!

Many wet boggy places explored. Good collection of bugs, a toad and a newt. 
And of course, cos boys, many many many special rocks.
