Rio Grande del Norte National Monument, Nature reserve in Rio Arriba County, US.

Rio Grande del Norte National Monument covers about 242,555 acres (98,159 ha) of public land in Taos County, New Mexico, centered on the Rio Grande Gorge. The river cuts through the Taos Plateau volcanic field, exposing basalt and rhyolite walls, and the monument also takes in the gorges of the Rio San Antonio. Ute Mountain, at 10,093 feet, is the tallest peak entirely inside the monument.

People have lived in the Rio Grande valley for at least 7,500 years. Hundreds of petroglyphs are carved into the cliffs, with dense clusters near the hot springs in the gorge, some dating to the Archaic period. Archaeologists have found pit-house remains, potsherds, tools, projectile points and large ceramic vessels. The Jicarilla Apache, Utes, Taos Pueblo and Picuris Pueblo used the area; later artifacts mark Hispanic explorers and settlers from the early 18th century, and abandoned 1930s ranches remain.

Hundreds of petroglyphs are carved into the cliffs, ranging from abstract spirals and dots to clear figures of people and animals, with dense clusters near the hot springs in the gorge. The Jicarilla Apache, Ute, Taos Pueblo and Picuris Pueblo peoples used this area, and later artifacts and images mark the routes of Hispanic settlers and explorers from the early 18th century.

The monument has five campgrounds offering basic facilities and can be reached via paved highways from nearby towns. Two Bureau of Land Management visitor centers provide information to help plan your visit and answer questions about the area.

The monument contains two wilderness areas, Rio San Antonio and Cerro del Yuta, which were officially designated in 2019 through federal conservation law. These sections offer visitors remote hiking trails far from the main access points.
