The caravan was in Spain's Basque Country for three days after traveling to Ceuta and Melilla to denounce the ''current policies of the European Union on immigration and the context of militarization and shutdown of borders, which causes misery and death'', said a spokesman for the organization. About 100 organizations and human rights collectives, along with associations to help migrants, promote gender equality, unions and leftist parties, including Spain's Podemos and the Basque Bildu, have joined the platform in Spain. 

Hundreds of participants in the initiative 'Mugak Zabalduz-Abriendo Fronteras' stopped by the migrant detention center in Hendaja, in front of the arms factory of Andain and the port of Bilbao to raise the public opinion's awareness on the condition of immigrants in the Basque country and the arms trade with war-torn countries. The weapons were in containers, ready to leave from Santurztzi. The objective was to denounce ''economic policies that cause wars, the exploitation of natural resources, labor and social exploitation and impoverishment, which lead to the exodus of millions of people worldwide'', as noted in a statement. 

Activists on the last day of the demonstration gathered in front of the Basque Parliament to protest against human trafficking. Under a heavy rainstorm, the march walked through Bilbao to reach the local office for foreigners and the local prefecture in Bizkaia in a funerary march opened by symbolic caskets to denounce migrant deaths in the Mediterranean and ''immediate, systematic expulsions at the border between Spain and France''. The network recalled that 2017 was a particularly deadly year with over 3,000 victims in the Mediterranean, including at least 223 who drowned as they attempted to reach Spain's coasts, according to data provided by the International Organization for Migration. On February 3, the Caravan stopped in Ceuta to mark the anniversary of Tarajal, where 15 migrants died on February 6, 2014, as they were trying to reach the beach of the Spanish enclave in Morocco. 

In June 2017, the network of activists mobilized in Melilla to denounce the ''constant violation of human rights at the southern border of Europe''. It also denounced the inhuman condition of some 30,000 people, mostly women exploited to bring goods to the Spanish enclave by local criminal gangs, who cross the border on a daily basis and risk being crushed by the crowd. ''With this caravan we want to highlight the key role of migrant people, backing their fight against exploitation and promoting the international right of free circulation and a policy of effective hospitality'', said a spokesman for the network. ''We are not accomplices of these murderous policies - for this reason, it is necessary to break the wall of indifference that is growing in our territories''.
