Parque Joya La Barreta, Ecological park in Querétaro, Mexico.

Parque Joya La Barreta is a 2,450,000 m² municipal property northwest of Querétaro city, near the Guanajuato border. It lies within the Zona Occidental de Microcuencas protected area and holds oak forest with a canopy up to 10 m high, crasicaule scrub with nopal and garambullo, thorn scrub, tropical deciduous forest, grassland and cliff vegetation. The largest oak patch forms a belt south of the microcuenca.

The land transitioned from agricultural use to public natural space through government action and was formally opened on September 18, 2003. This conversion marked an important shift toward protecting the mountain forests in this region.

The park belongs to the municipal protected area Zona Occidental de Microcuencas, the source of runoff for the western part of Querétaro. Its oak woods, cactus scrub and tropical deciduous forest are studied for the environmental services they provide to the municipality. Visitors can join guided tours and educational programs about these ecosystems.

The park lies about 40 km northwest of Querétaro city, reached via the national highway 57 toward San Luis Potosí, then a turnoff to San Miguel de Allende, 6 km to La Monja and 7 km of cobbled road past La Barreta; the drive takes around 50 minutes. The entrance is before La Joya. Wear sturdy footwear and carry water for the uneven mountain trails.

The park's vegetation survey recorded 106 plant species in 84 genera and 38 families, with legumes (Fabaceae) and cacti the richest groups. Three of these species are rare or hold a conservation status. The dominant tree in the wooded patches is the oak Quercus aff. castanea, forming a canopy up to 10 m tall.
