Some ideas…!!
No. 19 Play pooh sticks
The suspension bridge at Whitelady Waterfall is a great place to play pooh sticks. The whole family can line up with their chosen stick to see who will win.
If you take the full Lydford Gorge trail then you could play pooh sticks on all the bridges and see which is your favourite.
No. 5 Skim a stone
Pixie Glen has a wider and quieter stretch of river good for skimming stones, see who can skim the furthest or get the biggest number of skips. Also look out for the pixie door in one of the trees in this area.
