Conjunto Arqueológico Dólmenes de
Antequera is three dolmens…read moreat two sites, and they are part of Antequera's natural UNESCO World Heritage sites (including El Torcal and Peña de los Enamorados). All sites are free to visit, with free parking.
You do need a ticket from the ticket office before you can enter the dolmens sites, and there are two locations so make sure you visit the ticket office first. At the main site, with Viera and Menga dolmens, there is a museum covering all. You must drive to a separate location for El Romeral dolmen.
We parked free at Viera (Megalithic) and Menga (Neolithic) dolmens, got tickets inside the museum, and only had time to visit those two dolmens. (El Romeral dolmen is slightly less-prehistoric, from the Chalcolithic era.)
The Viera dolmen is an amazing feat of prehistoric architecture, with giant stone slabs erected to shelter as a tomb under an earth-covered mound. The Menga dolmen is similar except it has a wider corridor with post-and-lintel division, and a deep well in the chamber.
The Menga dolmen (again of the Neolithic era) is deliberately built facing Peña de los Enamorados. On Peña de los Enamorados, the Abrigo de Matacabras, on the northern side of this rock formation, has Neolithic cave paintings (the paintings cannot be visited).
Note that in travel videos I saw people touching the walls all over but don't so much as brush a stone with your clothing by losing balance as you walk because the one guide was a b!ch! Holy sh!t she was up our rears. Not sure if this is xenophobia, some issue with kids, or this girl was a nutcase, but all you need to do is politely tell people not to touch the stones. You might want to check out YouTube videos taken when you guides aren't looking because these cavities have had a good feel-up by many gropers far worse than my innocent child who brushed it simply trying to navigate a tight space next to others. Guide needs a major attitude adjustment! Really uptight when people are trying to relax and enjoy a World Heritage Site.
