The Guns of Mazarrón is all about scenery, history and the outdoors. After a scenic drive to the top of the mountain you’ll find abandoned buildings, which look almost castle like and two massive Vickers guns (38.1 centimetre 1926 models). The guns were apparently last fired on the 26th April 1973 by Republicans at a group of Nationalist cruisers. In such a tranquil setting it is hard to imagine the boom that the guns would have made as their artillery travelled the 20 miles to its target.
There are several things to be aware of. You must be a confident driver, as the road is very twisty and narrow in some places with steep drops to one side. There are no facilities of any kind at the guns, so bring a picnic with you. Make sure you wear good shoes for walking over rough ground and if you want to explore the underground tunnels (all at your own risk), then bring a torch.
