Four miles of road walking. Doesn't sound a great day out, but I'm not the only one trudging the tarmac along the Arisaig coast road. At each small bay and cove, people with cameras and binoculars peer expectantly out to sea. And with good reason … this is one of the UK's otter hotspots.

I go walking to get away from other people. Not completely – a cheery ‘hello’ is always welcome, as is a good walking partner (i.e. one who doesn’t talk too much) – but, like many walkers, I want to avoid the crowds. I want to ‘get away from it all’, ‘head off the beaten track’ and other such clichés.

During the winter months in Scotland, the weather can change hourly and only a fool would pre-empt the forecast more than a day in advance.However, on this occasion, good luck was the reward for some advanced planning and the three of us were provided with some of the best mountain days ever experienced.
