its no more than a mile from the Blauc Parc, ive been up it a couple of times to the top where as Stephen says there is a small white chapel with a virgin mary statue inside, you can just see it if you look carefully from the Blau Parc. Just climb up the hill as the crow flies, there seems to be numerous pathways, once you at the top there is an easier slope down to calla gracia...have fun but its quite steep!!
