Hike the South Valle Grande Trail

NPS
The South Valle Grande Trail is a pet-friendly hike that descends the southeastern rim of the caldera to the edge of Valle Grande. Because this trail transitions between two habitat types—mixed conifer forest and montane grassland—it hosts great biodiversity and is a renowned wildlife viewing spot, especially at dawn and dusk. Bring your binoculars for best results!
Predominant plant species include blue spruce, ponderosa pine, foxtail, and yarrow. A variety of wildflowers adorn the edge of the trail throughout the summer months.
The South Valle Grande Trailhead is located on the north side of NM-4 near mile marker 43. Park in the paved lot on the south side of NM-4, opposite the trailhead. Please use caution when crossing the highway at the beginning and end of your hike.
Elevation: 8,653 - 9,081 feet
