An excellent online resource is Walkhighlands:
It has low and high altitude route descriptions, with short and longer, more strenuous excursions. Maps too, and readers submit their own experiences and photographs. I don't work for Walkhighlands, in case you wondered!
The link takes you to Coire Ardair, near Loch Laggan.
The big panoramic photograph (click on it, if it isn't displaying at full size), was taken at the high lochan below the summit cliffs on Sunday. A magnificent place, very wild and hidden away, but surprisingly easy to get to, with no navigation worries. It takes a couple of hours to walk there, on a good path.
