At a Glance

  • South Fork of the Rio Ruidoso, one of the clearest and most scenic streams in southern New Mexico
  • Riparian corridor with willow, alder, and cottonwood
  • Views up toward Sierra Blanca as the canyon opens in the upper section
  • Good trout fishing in a designated wild trout section of the creek
  • Less crowded than the main Ruidoso tourist areas despite close proximity

Overview

The South Fork Trail follows the South Fork of the Rio Ruidoso from the campground day-use area upstream through a classic Southwestern mountain creek canyon. The stream runs clear and cold year-round, fed by springs and snowmelt from the Sierra Blanca massif above. The riparian corridor of willow, alder, and cottonwood provides shade, birdsong, and the constant companionship of moving water.

This trail is one of the better-kept secrets near Ruidoso, a town known more for its racetrack and ski area than its hiking. The South Fork drainage offers genuine mountain creek scenery within Lincoln National Forest without the crowds of the developed recreation areas. Anglers, birdwatchers, and families looking for a shaded creek walk all find what they need here.

The Route

Campground to Canyon Entry (Miles 0-1.2) The trail begins at the South Fork Campground day-use area and follows the creek bank upstream immediately. Several shallow crossings on stepping stones occur in the first mile. The canyon walls are low and the corridor is open.

Canyon Narrows (Miles 1.2-2.8) The canyon closes in and the trail becomes more intimate with the creek. Cliffside ledges force the trail onto the creek bank in several spots. Willow grows dense along the water's edge, and the canopy closes overhead in summer. This is the best section for fishing.

Upper Valley and Views (Miles 2.8-3.4) The canyon opens into a broader valley near the turnaround. Views of the upper Sierra Blanca massif appear at the canyon head. A large pool at mile 3.2 is a popular fishing spot. Return by the same route.

When to Hike

April and May the creek is running high from snowmelt and spring rain. The riparian zone is at its greenest, and spring migration birds pass through.

June through August the creek is lower but still flowing. The shaded canyon is noticeably cooler than open terrain.

September and October fall color from the cottonwood and alder makes this one of the most photogenic creek walks in the region. Fishing remains good into October.

What to Bring

Many hikers carry 1.5 liters of water. Creek water requires treatment before drinking. Waterproof shoes are useful for creek crossings in early season. A fishing rod and New Mexico license are worthwhile for anglers. Light layers are useful in the shaded canyon sections.

Trailhead Access

The trailhead is at the South Fork Campground day-use area, reached via NM-532 south of Ruidoso near Mescalero. No day-use permit or fee is required as of 2026. A vault toilet is available.
