Purple saxifrage?

Munro 281 was climbed today (Aonach Beag) which leaves me with just one more to do with family and friends in July.
I saw 2 folk on the hill all day until I dropped down to the top Gondola station at the Ski Centre which was busy with day trippers and cyclists.
The Aonach ski centre is transformed into a major centre of down hill mountain biking in the summer and the runs are of very high quality. The World Championships were held here last week.
I came across this purple flower at 1300m - a splash of colour in a tundra type landscape at that height. ? Purple saxifrage
