Well it's coming to the end of our visit this year.

I have done 3 hikes up the Sierra Almagrera. One of them was over 6 hrs and was completely nude.
I have been to three different summits, there are about 3 more all virtually the same height. They are around 320m above sea level.
On 2 of the peaks there was an unmarked mine shaft within 20m of the summit cairns right at the top! So constant care is needed!
Above Los Lobos I found the partially restored steam engine which is the oldest of it's kind that is still in situ anywhere in the world. Other mining evidence is everywhere and I also saw the tramway tunnel that linked Los Lobos with Cala de Conches on the coast.
In about 12 hrs hiking only saw 12 other hikers that were in a group.
