Using GIMP, I decomposed the image using the LAB color model.
Of the 3 decomposed layers L,A,B, I only adjusted the A and B layers
using curves. This gave me the colors I was looking for.
I created a duplicate layer and desaturated it.
I added a Gaussian blur to this layer and set it's mode to overlay.

I think you've overdone it a bit with the blur. It would be good to see the 'after' image before you blurred it. The colours are a bit too saturated for my liking, but not by much, and I feel that it could be cropped just a bit to bring the trees a bit further to the right of the image. Saying all that though, it's a vast improvement from the dull colours of the 'before' image.
I like the end result you achieved with this. I suppose it might be a bit saturated for some tastes but I don't mind the slightly surreal quality. I think it's more interesting then the original.
I, too, would like to see what it looked like before the Guassian blur. It's always fascinating to see the way some of those tools manipulate an image. The variety of uses are almost limitless when you consider blending them with others and adjustments.
