The Section 27 of EuroVelo 1 in Andalusia, will take us through the 36 km that separate Nerva from Valverde del Camino, joining the Huelva regions of the Riotinto mining basin and the Andévalo.
We leave Nerva and, after crossing the A–476 regional road, take the paved and isolated HV–5015, which runs along the banks of the Tinto River, in the middle of an open landscape transformed by mining activity. Here we will find landmarks, such as the ruins of the old Copper Foundry or the Tourist Mining Railway, restored from the original for the use and enjoyment of visitors.
After a few kilometres, EuroVelo 1 takes us to the small town of Minas de Riotinto. We enter by the regional road and find ourselves in the centre of the town. Here, it is said to be the birthplace of Spanish soccer and the locality where the first environmental demonstration in the country was held. Without a doubt, there are many places to visit here, such as those to the Corta Atalaya, the Mining Museum or the English Quarter of Buena Vista.
Our route leaves Minas de Riotinto on a track that runs close to the regional road and leads us to the town of El Campillo, where we connect with the Greenway of Riotinto, the former route of the mining railroad that connected with San Juan del Puerto.
After about seven kilometres, EuroVelo 1 takes us to the town of Zalamea La Real, in the Andévalo region, which contains a rich monumental and urban heritage as well as some excellent examples of the best megalithic art.
After leaving Zalamea La Real, we find the village of Membrillo Alto, from which we can take a detour of about four kilometres to visit the Natural Monument Acebuche del Espinillo or continue towards another of the villages of Zalamea La Real, El Pozuelo, where the aforementioned megalithic site is located, the Dolmens of El Pozuelo.
From this point, the Green Route crosses the national road on two occasions, continuing close to the Arroyo del Buitrón until it makes a final turn towards Valverde del Camino, a town jealous of its artisan tradition of country footwear, iron and copper forging, and liquor distilleries.
