Fly Fishing Pecos River - Upper

Fly fishing upper Pecos River is a quintessential small-stream mountain fishing experience in the southern Sangre de Cristo Mountains, offering intimate pocket water, native and stocked trout, and the cool pine-scented air of a high-elevation forest setting just 90 minutes from Santa Fe. This 10-mile section runs from Cowles downstream through the Pecos Wilderness boundary and Holy Ghost Campground area, closely paralleled by NM-63 as it winds through a narrow canyon of mixed conifer and aspen forest. The Pecos here is a classic small freestone, typically 15 to 30 feet wide, tumbling over boulders and bedrock ledges in a continuous series of plunge pools, pocket water, riffles, and short glides. Elevations range from 7,500 to 8,500 feet, keeping water temperatures cold enough to support trout year-round.

The upper Pecos supports brown trout, rainbow trout, and Rio Grande cutthroat trout — New Mexico's state fish and a species of conservation concern. Browns and rainbows are the most commonly encountered, with NMDGF stocking supplementing natural reproduction near campground access points. Rio Grande cutthroat inhabit the upper reaches and tributary streams, with Holy Ghost Creek being a notable cutthroat stronghold. Fish generally run 8 to 13 inches, with occasional browns to 15 inches in deeper plunge pools. The intimate scale demands light tackle: a 7.5- to 9-foot rod in 3- or 4-weight paired with 5X to 6X tippet for the clear mountain water.

Spring fishing begins tentatively in April with early Baetis mayflies on warming afternoons. By late May, caddis emergences intensify and small stoneflies appear along boulder-strewn stretches. Summer from July through September is prime time, with prolific evening caddis hatches, terrestrial activity during warm afternoons, and attractor dry flies like Parachute Adams, Elk Hair Caddis, Royal Wulffs, and foam beetles producing consistently. Hopper-dropper rigs are deadly through August and September — a size 10-12 foam hopper trailing a beadhead pheasant tail or prince nymph. The classic approach of prospecting with a single dry fly through pockets and plunge pools is the most enjoyable technique here.

NM-63 follows the river from the Village of Pecos through Terrero to Cowles with numerous pullouts and Forest Service campgrounds. Holy Ghost Campground, where Holy Ghost Creek joins the Pecos, is a popular base camp and fishing access. The Bert Clancy Fish Hatchery near Cowles marks the upper end of road-accessible water, and trails continue into the Pecos Wilderness for backcountry cutthroat fishing. Santa Fe, 45 minutes west, offers extensive lodging and fly shop services, including High Desert Angler (since 1985) and The Reel Life, both specializing in Pecos River outings. Albuquerque International Sunport (ABQ) is approximately 90 minutes southwest via I-25 and NM-63.
