One of my favourite hills was looking superb in the early morning May sunshine, as I walked up Coire Ardair.

But it was also an astonishing surprise to see the regeneration of native woodland since my last visit.

I could hardly believe that the forests of birch, rowan and alder have grown so much since my last walk here in around 2006. Well done to the managers of the National Nature Reserve who have ensured this wonderful regeneration. It gave me a glimpse of how much of Scotland used to look - and, hope for the future!

The forest floor was starred with wood anemones, primroses and violets.

I wandered slowly along, and the crags began to loom bigger above the Allt Coire Ardair.

The corrie ahead.

Big crag, small stream.

The outflow from the lochan.

Water sparking on the rocks.

I sat on the shore of the lochan for about an hour. It was a wondrous place, and I had seen no-one. Just like Camusdarach the previous day, it felt like a private heaven.

Finally I started walking, and immediately had a different perspective on the corrie.

Close-up crags.

Alpine scenery, on a near-Alpine scale.

Last time I did this walk to the Window, I was wading through thigh-deep snow and watching anxiously above for signs of avalanche at this notorious spot. This time I was surprised how easy the ascent was. Soon the Window looked quite close.

The distant figures in this view were the only two people I saw during the whole walk.

IMG_4767 by Half Man Half Titanium, on Flickr

Mad Meg's Cairn, the summit, and Lochan Uaine.

A higher view, with the Loch Lochy hills in the distance.

Mad Meg's Cairn. To me it looked much older, but the story told about this cairn is that it marks the grave of an 18th century suicide. Her family were not allowed to buy her in the kirk's consecreated ground. A sad and comfortless story, except that her family must have cared deeply to bring her body up this remote spot.

Looking back to the Cairn from near the true summit.

South from the summit. Schiehallion can be seen faintly on the left, Ben Alder and Geal Charn above Ben a'Chlachair in the middle, and Aonach Beag and Beinn Eibhinn on the right.

IMG_4807 by Half Man Half Titanium, on Flickr

South-west from the summit- an array of hills from Stob a' Choire Mheadhoin to Ben Nevis.

IMG_4806 by Half Man Half Titanium, on Flickr

I went back to the Window and started the short easy climb of Stob Poite Coire Ardair, with a great view down into Coire Ardair.

Another angle on the corrie.

The ridge to Sron Coire a'Chriochairean, my final objective for the day.

IMG_4836 by Half Man Half Titanium, on Flickr

A bit closer.

IMG_4837 by Half Man Half Titanium, on Flickr

The cairn on Sron Coire a'Chriochairean - another fine viewpoint where I whiled away a half-hour contemplating the scene.

IMG_4838 by Half Man Half Titanium, on Flickr

A contrasting view from the cairn - the bleak wilderness of the Monadh Liath.

IMG_4840 by Half Man Half Titanium, on Flickr

I descended into beautiful Coire a'Chriochairean.

Afternoon light on Puist Coire Ardair.

A last look back at Coire Ardair.

The view down the path from the same point, with Loch Laggan, Geal Charn and Creag Pitridh.

Late afternoon light on the lowland meadows at Aberarder.

Yet another walk I will repeat again soon - partly for the fine upland scenery, and partly for the lush forests which are being allowed to reclaim this wonderful place.
