Do frogs move around much?

[Tringa]

A few years ago I was walking in NW Scotland and found a frog hopping among the shattered rocks at about 950m on mountain in the Letterewe Forest.

Does anyone know what it would do in the winter?

Frogs in my pond seem to sit out the winter in the mud at the bottom; but the pond never freezes. At the level I found this frog the overnight temperature is well below freezing for many months and in winter the ground freezes and is snow covered.

Do frogs on mountains move down in the winter and back up again in summer?

TIA
