we walked up a bit of a mountain in the rain at Beinn Eighe. There's a great choices of walks, from the flat wheel chair nature trail through to a proper up-a-mountain trek (which was a bit too ambitious for us). there's a nice visitor centre and good children quizzes.

instead we did the bite-size 'quite far up the mountain, but not too bad' one which gave us great views over loch maree

it had all your classic walking things, like stepping stones over mountain streams, before finaly getting back down to loch level.
