The treetop walk was quite a structure. Designed to look like tree trunks, this walkway enabled us to walk up high among the tops of the trees, giving us a view over Kew Gardens, and far off into the distance, the centre of London itself. The planes seemed to fly overhead lower than ever, almost as if we could reach out and touch them. We did not spend much time up here, however, due to the fact that every time we stood still, we felt the structure sway in the breeze... and being 18 metres up, it was not a very reassuring feeling! It was perfectly safe, but we were not the only ones to feel less than secure up there!
