When national teams from Brazil and other CONMEBOL top sides travel to Bolivia in the South American 2030 World Cup qualification, they embark on one of the most unpleasant away trips in international football. The Estadio Hernando Siles in La Paz sits at approximately 3,580 meters above sea level – and has been one of Bolivia's greatest sporting weapons for decades. Even more extreme is the higher-altitude Estadio Municipal de El Alto, which at around 4,070 to 4,100 meters according to various sources, is now also used for international matches.
The thin air means that upon rapid ascent, there is reduced oxygen availability and can impair physical performance and recovery. Studies on altitude exposure show, among other things, declining oxygen saturation and reduced maximum oxygen uptake; acclimatization can partially mitigate these effects. Players arriving from lower altitudes in the short term can therefore suffer from symptoms such as headaches, dizziness, or faster fatigue. The ball's aerodynamic properties also change: due to the lower air density, it can fly further and faster, while its trajectory and curve behavior change. This can be particularly significant for long balls and shots.
Statistics support the myth – though not every spectacular figure at the same venue. In qualification for the 2026 World Cup, Bolivia achieved a much-noticed 1-0 victory against Brazil on September 9, 2025, but not at the Hernando Siles, rather at the even higher-altitude Estadio Municipal de El Alto. Brazil lost there at approximately 4,100 meters altitude through a goal by Miguel Terceros. The result reignited debate about the altitude advantage, but is strictly speaking not evidence of Bolivia's home strength at the Hernando Siles.
That altitude can also play a role in La Paz is demonstrated by Bolivia's legendary 6-1 victory over Argentina on April 1, 2009 at the Estadio Hernando Siles. Bolivia won the World Cup qualification match against the Argentine side coached by Diego Maradona 6-1.
FIFA actually attempted in 2007 to ban international matches above 2,500 meters. After massive protests from South America, the limit was initially raised to 3,000 meters; La Paz thus remained excluded. Bolivia's then-president Evo Morales joined the protest campaign, even playing football himself at great altitude in a demonstration. That regulation was later not maintained as a permanent altitude ban for La Paz. For 2030 World Cup qualification, no confirmed new FIFA plans for a corresponding ban are currently known publicly; such a development would therefore need to be marked as speculation.
Sportily, Bolivia faces a tremendous challenge. Since the 1994 World Cup in the USA, the team has not qualified for another World Cup final tournament. In qualification for the 2026 World Cup, however, Bolivia finished seventh and reached the FIFA playoff tournament, but failed there against Iraq in March 2026. Home matches at great altitude thus remain an important element of Bolivia's strategy in the fight for World Cup participation.
For 2030, however, one should not speak of an already-determined "South American World Cup qualification" with a concrete format. While FIFA has designated Spain, Portugal and Morocco as hosts and Argentina, Paraguay and Uruguay as hosts of the three jubilee matches; these six countries are automatically qualified. The exact qualification path for the remaining CONMEBOL teams, however, has not yet been fixed in an official 2030 match schedule.
The debate about fairness is not purely Bolivian either. Ecuador also plays its home matches in Quito at approximately 2,800 meters, while Colombia traditionally uses Bogotá as a venue. The fundamental question therefore is how much natural location conditions should be considered in international football. A blanket altitude ban would particularly affect countries whose most important stadiums are located in high-altitude cities.
For fans, Bolivia is certainly a piece of living World Cup folklore. Which teams ultimately actually qualify for the tournament in Spain, Portugal and Morocco and when the decisive matches at altitude kick off is shown by the current World Cup qualification schedule. One thing is certain: if Brazil, Argentina, or another top team must take to the field in La Paz or El Alto again, the altitude question will once again play a central role.
