San Juan County

San Juan County is an administrative area in northwestern New Mexico covering expansive land with several rivers and mesa formations. The landscape is shaped by the San Juan River, Animas River, and La Plata River, which flow between elevated plateaus and open valleys.

The county was established in 1887 and became an important administrative center for the region. From its early days, it developed through settlement and economic growth into a significant area in northwestern New Mexico.

This area is home to Navajo communities and carries deep indigenous roots that shape daily life and local identity. You notice this heritage in place names, traditional crafts, and how people connect with the landscape around them.

When exploring, you'll find schools, hiking trails, and opportunities for water sports along the rivers. Plan for a large area that requires travel time between different locations.

The area holds two major archaeological sites: Aztec Ruins and portions of Chaco Culture National Historical Park. These places reveal remains of ancient Pueblo cultures that thrived here centuries ago.
