Pagosa Springs is a small mountain town in southwestern Colorado where the San Juan River flows right through the center of town, past the world's deepest geothermal hot springs. The juxtaposition is perfect for a fishing trip: you spend the day wading cold water for trout, then soak in a 104-degree mineral pool while the sun sets behind the San Juan Mountains. Very few fishing towns offer that combination.
The fishing radiates outward from town like spokes on a wheel. The San Juan River runs through Pagosa and holds solid populations of brown and rainbow trout in a freestone setting. The Piedra River flows south through a remote canyon holding wild trout in roadless water. The East Fork of the San Juan climbs into the high country with cutthroat and brook trout in pocket water above 10,000 feet. And Navajo Reservoir, an hour south on the New Mexico border, adds kokanee salmon, pike, and bass to the menu.
The San Juan River, Through Town
The section of the San Juan River flowing through and below Pagosa Springs holds brown trout and rainbow trout averaging 12 to 16 inches, with fish over 20 inches in the deeper pools and undercut banks. The river is a classic freestone, riffles, runs, pools, and pocket water carved through a mix of meadow and canyon.
The through-town stretch is accessible on foot, you can fish the San Juan on a morning walk from your hotel. Below town, the river enters a canyon where the water deepens and the trout get larger. Float trips through the lower canyon cover water that's inaccessible from shore and hold the biggest browns in the system.
Hatches drive the dry-fly fishing: Blue Winged Olives in spring and fall, caddis from May through September, Pale Morning Duns in summer, and golden stoneflies in June and July that bring big trout to the surface in the faster water. Hopper fishing in August and September is the most fun, foam grasshopper patterns fished tight to the grassy banks produce explosive strikes from browns that have been waiting for exactly that.
The San Juan fishes best from late June (after runoff clears) through October. Fall is the local favorite, brown trout color up and move through the system on their pre-spawn migration, the aspens turn, and the crowds from summer have gone.
The Piedra River, Wild Canyon Water
The Piedra River is the hidden gem, a tributary of the San Juan that flows south through a remote canyon in the San Juan National Forest. The upper Piedra is designated Wild and Scenic, and the fishing matches the designation: wild trout in wild water, with minimal access and minimal pressure.
The Piedra holds brown trout, rainbow trout, cutthroat trout, and brook trout in a diversity that reflects the river's varied character, pocket water in the upper canyon, longer pools and runs in the middle sections, and larger water near the confluence with the San Juan. The special-regulation stretch from Lower Piedra Campground upstream to Sand Creek is artificial-only with a two-trout, 16-inch minimum limit, managed for quality.
Getting to the best water on the Piedra requires hiking. The canyon is steep-sided and the trail access is limited, which is exactly what keeps the pressure low and the trout willing. Scout the access points and wading routes before you go, a little homework puts you on water that feels genuinely remote, a half-hour from town but a world away from the crowds.
The East Fork, High-Country Water
The East Fork of the San Juan River climbs into the high country east of Pagosa Springs, following Highway 160 toward Wolf Creek Pass. Above 9,000 feet, the river narrows to a small mountain stream holding cutthroat trout, brook trout, and cutbow hybrids in pocket water, plunge pools, cascades, and short runs between boulders.
The fish are small, 6 to 12 inches is typical, but they're brilliantly colored, willing to eat dry flies, and living in some of the most beautiful mountain scenery in Colorado. The East Fork is the spot for anglers who want the high-country experience: thin air, wildflowers, and native trout in a creek you can step across.
Wolf Creek and Treasure Creek, small tributaries feeding the East Fork, hold even smaller cutthroat in genuinely backcountry settings. These are hike-in fisheries that reward effort with solitude.
Williams Creek and Echo Canyon
Williams Creek Reservoir sits north of Pagosa and holds stocked rainbow trout, brown trout, and kokanee salmon in a mountain-lake setting. The creek below the reservoir is a tailwater that fishes well year-round, and the canyon section offers wadeable pocket water with less pressure than the main San Juan.
Echo Canyon Reservoir is a smaller, quieter option with stocked trout and a scenic setting.
Navajo Reservoir, The Big Water
An hour south of Pagosa Springs, Navajo Reservoir straddles the Colorado-New Mexico border and offers fishing that's completely different from the mountain streams. The 15,000-acre reservoir holds kokanee salmon, northern pike, largemouth and smallmouth bass, and brown and rainbow trout in a high-desert canyon setting.
The kokanee fishery peaks in late summer and fall (August through October), with trolling producing fish in the 14- to 18-inch range. Northern pike grow to trophy size in Navajo, fish over 30 inches are caught regularly, and 40-inch fish are realistic. The pike hold in the weedy bays and channel edges, and they eat large lures with commitment.
When to Go
- Late June–July: Rivers clear after runoff, stonefly hatches, the season opens, arrive when the water drops
- August–September: Peak dry-fly fishing, hoppers on the San Juan, caddis everywhere, high-country streams open
- October: Fall brown trout migration, aspen colors, the locals' favorite month
- November–March: Lower San Juan stays fishable with nymph rigs; Navajo Reservoir for pike year-round
