The Rio Grande Trail is a proposed long distance trail along the Rio Grande in the U.S. state of New Mexico. The river extends over 1,800 total miles, some 700 miles (1,100 km) of which pass though the heart of New Mexico. It is the state's primary drainage feature and most valuable natural and cultural resource. The river and its bosque provide a wide variety of recreation, including hunting and fishing, birdwatching, river rafting, hiking, biking, and horseback riding. The river also flows through or beside numerous spectacular and geologically interesting landforms, the result of extensive volcanism and erosion within the Rio Grande Rift. Although some trail advocates would like to see the trail extended the full distance through New Mexico, from the Colorado border to the United States–Mexico border, the portion proposed for initial development extends 300 miles (480 km), from Bernalillo south to Las Cruces.
Governor Bill Richardson and New Mexico State Parks proposed the establishment of this trail. In 2006 the New Mexico Legislature provided funding to begin planning and development of the project. In April 2015, the Rio Grande Trail bill was signed by Gov. Susana Martinez, which creates a commission composed of state and local governments, activists, and local pueblos and tribes.
The core of the proposed trail is the existing Paseo del Bosque Trail in Albuquerque, a product of long-standing collaboration among numerous interest groups and agencies including the Middle Rio Grande Conservancy District, which also maintains ditchbank trails in Corrales and other communities in the area.
