Though the news has focused on Central American migrants arriving in the United States, tens of thousands of people from countries around the world are also making it to the southern border. For Pravan and Sabjajit, their journeys began two years ago. In 2016, Pravan flew from India’s western coastal state of Gujarat, India to Guayaquil, Ecuador. A computer engineer by training, Pravan worked in Guayaquil to save money for his trip and subsequently became conversationally proficient in Spanish, his fifth language. Sabjajit—who is originally from Punjab in northern India—arrived in Guayaquil only three weeks before their arrival in Capurganá. When the two men met in Ecuador, they decided to travel north together. In just a few weeks, they had reached this town in northern Colombia, where they would wait for several more of Sabjajit’s friends from Punjab before continuing on to the Panamanian border.

In 2016, the Panamanian border patrol reported that it apprehended almost 20,000 migrants arriving irregularly from Colombia, while migrants who registered their transit with Colombian authorities came in at close to 34,000 for the same year. In an interview with Juan Gomez, a journalist and expert on migration in Colombia, he estimated that the number of migrants passing through Colombia is likely closer to 100,000 per year. According to Gomez’s data, half of the migrants come from India, and many others come from Cuba, Nepal, Bangladesh, and Eritrea. In 2017, migrants crossing into Panama also included people from Iraq, Sierra Leone, Yemen, Angola, and around 30 other countries.

These migrants are trying to escape wars, climate change, religious persecution, a lack of economic opportunity, and gendered violence. For example, migrants from Sierra Leone and Eritrea are frequently fleeing forced and indefinite conscription in their countries’ militaries. Others from Nepal have left a bleak situation after the 2015 earthquake destroyed vast parts of the country, and reconstruction has been slow. Pravan and Sabjajit each have a different reason for leaving India. Pravan fled Gujarat after facing persecution in his state for belonging to a Christian minority. Sabjajit hoped to reunite with his closest family member, a cousin living in New York.

Many of these migrants arriving to Capurganá hail from the middle and upper classes in their home countries. Much like Pravan, Asian and African migrants transiting through Colombia are often accomplished professionals who left careers as university professors, engineers, business owners and public servants. They are the only ones who can afford to pay the exorbitant fees associated with a journey around the world, often up to $30,000 per person.

The route to Capurganá—which is roughly the halfway point in many migrants’ journeys—is lengthy, complicated, and dangerous. Migrants arrive through one of three routes. For African migrants, the most common path is to arrive in Brazil by plane or cargo ship and to then travel to northern Colombia in cargo trucks. A second, cheaper option is to arrive in Brazil or Guyana and then travel through the Amazon rainforest to the Brazilian city of Manaus, generally on a small boat, before crossing into Colombia. The third option is Ecuador—which is the most popular with East and South Asian migrants—with most migrants arriving either to Quito or Guayaquil by plane, and then taking buses north to Colombia.

The route depends on the migrants’ nationalities and their smugglers’ preferred routes. Ecuador, Brazil, and Guyana serve as the most common entry-points for international migrants given the countries’ lax visa requirements. It is only once migrants cross into Peru or Colombia that issues of legality, authorization, or immigration enforcement become concerns. Pravan and Sabjajit avoided having to sneak into Colombia between ports of entry by using forged British passports. They then boarded buses and headed north along the Pan-American Highway until they reached Turbo, Colombia in the north of the country.

While buses serve as the primary transportation method for the majority of these migrants, they must disembark as they approach the Colombia-Panama border. This is the starting point of one of the world’s densest and most isolated stretches of jungle: the Darien Gap. This also happens to be the only passage between South and Central America. Within the Darien Gap, there are no roads or north-to-south rivers to help with navigation, and the only ways to successfully reach Panama are by trekking on foot or hiring a boat for the several hours it takes to circumvent this stretch. Migrants arrive on buses to the Colombian towns of Turbo or Necocli, and then must take a boat to one of three towns in the Darien Gap, including the town of Capurganá. From Capurganá, it takes anywhere from five to eight days to walk to the nearest road, town, or even the closest cell phone tower.

Nepalese immigrants, heading to the southern U.S. border, lie exhausted on the ground in the border checkpoint after crossing the jungle of Darién gap on January 28, 2015 in Darien, Panama.

For migrants who recount their journeys from the U.S., the Darien Gap is often remembered as the most difficult section of the entire journey. There are only two ways to try to make it through. The first is to hike through the thick brush, which takes at least five days. This route is physically taxing, often requiring hacking through the jungle with machetes in extreme heat, without any basic services, and with no shortage of mosquitos and other disease-carrying insects. During the rainy season, the small streams running east to west frequently flood their banks, washing migrants away with their strong currents. As well as these natural barriers, this section of the jungle is also controlled by the Clan del Golfo. This Colombian criminal organization, and paramilitary group, smuggles drugs through the Darien Gap’s boundaries. It also controls the flow of migrants by demanding a tax from each for the right to pass. Migrants must contract a guide to get through the jungle but are frequently abandoned or turn back after getting lost or injured.
