Maderas del Carmen
When the Big Bend National Park in the USA was established in 1935, there were efforts by individuals and organizations in Mexico to protect the area of the Santa Elena Canyon in Chihuahua and the Sierra del Carmen , which lie opposite Big Bend Park on the Rio Grande . But different views, cultural differences and political and economic interests in Mexico prevented the creation of this protected area. This changed in the 1990s with the idea of creating an international peace park . This was designed in a similar way to the US model of nature conservation and was to become a so-called sister park or bi-national park . Each country should continue to pursue and cooperate with its own management plan to protect its ecosystems.
The park rangers cooperate, but a border crossing over the Rio Grande, which forms the state border through the parks, is not possible for visitors.
