There's also a tiny, semi-arid desert in Norway (!) of all places - Kvitsanden (The White Sands) by Røros. (62 degrees 34 minutes North, 11 degrees 22 minutes East).
Semi-arid - annual precipitation at Røros (on a highland plain, far from the sea) is some 550mm or so, but some 150-200mm or so of this comes as snow.
The 'desert' itself is approx. a square kilometer (0.4 square miles) - large enough for desert-like phenomena like shifting dunes to occur, small enough that there aren't (to my knowledge) any wildlife there which you wouldn't also find in the surrounding area.
