One of the things I have yet to do is visit the catacombs that are under the city of Almería. They were built to provide safety during the Spanish civil war.
Some friends are coming over in June and they have booked to do a tour of the catacombs. Sadly, the tour they are doing is now fully booked. So we will have to book this trip for another time.
If you are interested in seeing the catacombs you can book tickets here. It looks like the price is only 3 euros a person.
