A spot in the distance could be a tiny rock much closer than you think, or a giant boulder miles away.

Giant boulders flanked a perfect crescent of pale gold, lapped by turquoise waves on one side and shadowed by enormous weeping trees on the other.

We walked for miles along the meandering riverbed, winding between giant boulders and pines.

Even in the dry, vehicles can 'high centre' - get stuck with all four wheels spinning on giant boulders in the river bed.

There we stood, stomachs full, mouths agape, as a river normally 200 metres wide was squeezed between two giant boulders six metres apart.
