THE best of walking is ridge walking. Swoop downwards from the peak, level off along a rocky crest, then rise again to another summit; and then do the same thing again, four or five or even eight times over. Let the ridge sides drop steeply 900m to a green valley where a river gleams among the alder trees; and beyond the valley another steep ridge, and another, and the sea reaching silver-grey into the furthest west.

For added interest let the ridge top be composed of three different sorts of stone. And you’ve started to understand why the area from Ben Nevis southwards to Glen Coe is some of the finest mountain walking there is in the UK.

I put "some of" so as not to annoy the lovers of Snowdonia, or the

English Lakes, or Skye, or Torridon. There’s a lot more of Lochaber than there is of Snowdonia; it’s one and a half times as large as Lakeland. It’s a whole lot easier to get to than Skye.

Still not convinced? In that case…

Follow me first onto one of the less celebrated summits, Ben Starav at the bottom of Glen Etive. Its long ridge is stony with moss, and leads into an easy scramble over blobby boulders of grey granite. But now drop into the green valley on the left and enjoy another aspect of it all. Steep grass and granite slabs shut

out the sky. Below the path a gloomy ravine, with the flash of a waterfall.

And at the valley foot, under green birch and dark pine, the cuckoo calls, and white water slides over granite that mysteriously is now coloured pink.

Next, let’s visit Bidean nam Bian. The rocks now are volcanic, grey-blue andesite and pinky-grey rhyolite, all of it great to climb on if you’re a rock climber. Enter Bidean up one of its three ravines, each with some of that great climbing rock hanging impressively overhead. It’s steep, and it’s gloomy, and it gets steeper, until all at once you emerge onto Bidean’s ridge, with bright sky around you.

Granite and volcanic rock; the third rock is called quartzite. It’s flat but cracked, like a city pavement after earthquakes. Follow it along the Grey Corries, where its sharp edges will slash your boots, but its flat slabs give almost-easy walking above the precipices.

By now you’re getting tired.

So take a break; and come back in February or March. The eroded path along the Mamores is gone, and instead a snow edge swoops like a breaking wave, the snow crisp and crunchy for your crampons. In the clear cold air of a classic winter day, views are southwards over half a dozen ranges to the dome of Ben Lomond.

At the bottom of every steep-sided ridge there’s a steep-walled valley. Some of those valleys contain the A82 (alas, how even lovelier would be Glen Coe without its busy road). But the others offer long through routes, with rugged paths and smooth Landrover tracks.

A comfortable track leads between the jaws of the Lairig Leacach, and down past small waterfalls while looking up at Ben Nevis and the Mamores. Then it’s down a river whose alder-shaded bank has green levels for the tent. An even lonelier glen – but still with a good footpath – leads you to a lochan and bothy that are completely out of it.

And however bleak the Blackwater, the last four miles, through a deep, steep glen of beautiful birchwoods, will leave you at Kinlochleven longing for the next really long walk with the big rucksack. Just as soon as your feet and shoulders have recovered from the first one.

Getting there

The Nevis Glencoe area is perhaps Scotland’s best for real walks reached without the use of a car. From within the UK, aim for Glasgow rail or bus station. The Citylink coach is particularly

useful, a lovely run past Loch Lomond to serve Bridge of Orchy (for Inveroran Hotel), Kings House, Glencoe village, Fort William, and Spean Bridge on its way towards the Isle of Skye. The West

Highland Railway is even more beautiful, its crossing of Rannoch Moor featuring in various Harry Potter films.

Where to stay

Accommodation is widely available, from cosy old inns to both SYHA and independent hostels, bunkhouses and camp sites. There is also a right of responsible wild camping anywhere in the countryside.

For those visiting without the benefit of a nasty tin box on wheels, I commend Kinlochleven. Reasonably easily reached by bus, and with useful facilities such as shops, it has a wide range

of good walks, from riverside to mountaintop, right from the village edge. From there a short bus ride lets you relocate to Fort William or Glen Coe. The alternative, for those with strong shoulders, is to arrive somewhere in the south (Dalmally, Bridge of Orchy) and trek north along the valleys – stopping off at Kinlochleven for a hot bar meal and a night in a bed – then onwards for Spean Bridge or Fort William. Such adventurers will note the quite frequent bothies, marked on the overview maps with a small hut symbol.
