Durango sits in the southwest corner of Colorado, where the Animas River tumbles out of the San Juan Mountains and runs right through the middle of town. The headline is a Gold Medal trout fishery, Colorado's highest classification, for wild brown and rainbow trout, accessible on foot from downtown. Add the world-class San Juan tailwater a short drive south, a handful of mountain lakes and high-country creeks, and you've got one of the most complete fishing towns in the Rockies. It has a strong fly-fishing reputation, but you don't strictly need a fly rod. This guide covers it, water by water, for a first-timer.

First: License and the Gold Medal Rules
Anyone 16 or older needs a Colorado fishing license, available online from Colorado Parks & Wildlife; one-day and multi-day options exist for visitors. One important wrinkle: the famous San Juan River tailwater is in New Mexico, so fishing it requires a New Mexico license, not a Colorado one, plan accordingly if you make that trip.
On the Animas, know the Gold Medal regulations on the 7-mile stretch through Durango (from Lightner Creek down to the Rivera Bridge): artificial flies and lures only (no bait), with a 2-fish limit at a 16-inch minimum, effectively a catch-and-release fishery for most anglers. The Animas is open year-round. Always check current CPW regulations for the specific stretch and any lake permits before you fish.
The Animas River: Gold Medal Trout in Town
The Animas through Durango is the main event, and its accessibility is what makes it special, the Animas River Trail and parks at 9th Street and 32nd Street, plus the area around the fish hatchery, put you on quality water within walking or biking distance of downtown. The river holds healthy numbers of wild brown and rainbow trout.
Because it's artificial-only, fly fishing is the dominant approach, and most days that means nymphing: drifting weighted flies along the bottom under a strike indicator, where trout do most of their feeding. A two-fly rig with a Pat's Rubber Legs stonefly and a Pheasant Tail or Zebra Midge dropper covers most conditions. When fish rise to a hatch, blue-winged olives in spring and fall, caddis and stoneflies in summer, switch to a dry like a Parachute Adams or an Elk Hair Caddis, and in summer a hopper-dropper rig is deadly and fun. A streamer like a Woolly Bugger swung through the deeper runs tempts the bigger browns, especially in higher or off-color water. A 9-foot 5-weight (an Orvis Clearwater 5wt) is the ideal rod.
Spin anglers aren't shut out, the Gold Medal water is "flies and lures only," which means artificial lures are legal (just no bait): a Panther Martin or Rooster Tail spinner or a small spoon, cast across the current and retrieved steadily, draws aggressive trout. (Bait fishing with worms or PowerBait is for the lakes and non-Gold-Medal water, not the Gold Medal stretch.)
Fly Fishing a Rocky Mountain Trout RiverTiming matters on the Animas: spring runoff typically blows the river out and colors it from roughly May into June, so the prime river season is late June through fall once flows drop and clear. Early summer through September is excellent.
The San Juan Tailwater: A Day Trip to World-Class Water
About 1.5 hours southwest, below Navajo Dam in New Mexico, the San Juan River is one of the most famous tailwater trout fisheries in the country, cold, clear, year-round flows packed with big, well-fed rainbows and browns. It's tiny-fly, technical water (midges and tiny mayflies, fished on 6X and 7X tippet with RS2, Zebra Midge, and small egg patterns), which makes it humbling but incredibly rewarding, and it fishes great even in winter when the Animas is cold. Remember it requires a New Mexico license. It's a bucket-list day trip from Durango, best done with a guide your first time given how technical it is.
The Mountain Lakes: Vallecito, Lemon, and the High Country
When you want stillwater or a wider variety of species, the lakes around Durango deliver. Vallecito Lake, ringed by the San Juan National Forest northeast of town, is the standout, it holds brown and rainbow trout, smallmouth bass, northern pike, walleye, and kokanee salmon, a remarkable mix. Troll spoons or a Mack's Lure Wedding Ring for trout and kokanee, cast soft plastics and crankbaits along the rocks for smallmouth, and throw big spoons or set sucker minnows for pike. Lemon Reservoir, a few miles northeast, is regularly stocked with brown and rainbow trout and kokanee and is an easy, family-friendly day trip, troll or bank-fish with Berkley PowerBait for stocked trout.
For high-country adventure, Vallecito Creek and the countless alpine lakes and streams in the San Juans hold wild rainbows, brookies, and native cutthroat in stunning settings, these are hike-in, light-tackle waters where a small spinner or a dry fly catches eager, beautiful trout.
Stillwater and River Trout Fishing in the WestSpin, Bait, and Fishing with Kids
For the easiest start, or fishing with kids, skip the Gold Medal river and head to Lemon Reservoir or a stocked pond, where a worm or Berkley PowerBait under a bobber or on the bottom catches stocked trout with little skill required. A simple 6-foot spinning combo, light line, and a bobber is the whole kit. The high-country creeks are also forgiving for a beginner with a spinner, eager wild trout in small water build confidence fast.
Reading the Animas and Wading Safely
The skill that catches Animas trout is reading where they hold and drifting your fly naturally. Trout sit where they can rest out of the heaviest current while food washes past, the seam where fast water meets slow, the soft pocket behind a boulder, the deeper slot along a cut bank, and the head and tail of every run and pool. Cast upstream of those spots and let the fly dead-drift back to you, mending the line (flipping the slack upstream) so the fly tumbles at the speed of the current. Drag, where the line drags the fly unnaturally across the surface, is the number-one reason beginners get refused, so a clean, drag-free drift matters more than a long cast. Watch your indicator (or your dry fly) and set the hook with a quick, low sweep on any pause or twitch.
A safety note, because the Animas is a real mountain river: the flows are strong and the freestone rocks are slick, so wade deliberately, use a wading staff and felt or studded boots if you're not sure of your footing, and never wade water you can't read. Early in the season and after rain the river can run high and pushy, when in doubt, fish the softer edges and the slower water near the bank, which is where the trout often are anyway. The 9th and 32nd Street parks give easy, gentle access that's perfect for a first-timer to learn on before tackling the bigger water.
More on the San Juan Tailwater
The San Juan is worth understanding because it fishes so differently from a freestone river like the Animas. A tailwater is a river below a dam, and the cold, stable, food-rich water released from the bottom of Navajo Reservoir grows enormous numbers of big, fat trout in a short stretch, but those fish see a lot of flies and feed on tiny insects, so success comes down to small flies (size 22–26 midges and mayflies), light tippet (6X and 7X), and a perfect drift. The famous "Texas Hole" and the flats below the dam are legendary. It's humbling water where a first-timer will catch far more with a guide who rigs the tiny flies, sets the depth, and reads the subtle takes, but landing a 20-inch San Juan rainbow on a size-24 midge is a thrill that hooks people for life. And because it's a tailwater, it fishes well all year, including the dead of winter when Colorado's freestone rivers are locked up, which is exactly why it's the go-to when the Animas is high with runoff or cold in winter.
Fishing the Mountain Lakes
The lakes reward a slightly different approach than the rivers. On Vallecito, the variety is the fun, you can troll a spoon or a Mack's Lure Wedding Ring for trout and kokanee in the main lake, then move to the rocky shorelines and points to cast tubes and crankbaits for smallmouth bass, or set a big spoon or a sucker minnow for the northern pike that prowl the weed edges. Kokanee (landlocked sockeye) are a summer trolling specialty and superb eating, run small, bright lures behind a dodger at the depth your fish-finder marks the school, and use a soft drag because they have tender mouths. On stocked Lemon Reservoir, keep it simple: a Berkley PowerBait rig on the bottom or a spinner cast from the bank catches planted trout with little fuss, making it a great family outing. Mornings are usually calmest and best on both lakes, as the San Juans tend to build afternoon wind and thunderstorms, get an early start and watch the weather, especially at altitude.
A Note on Conservation
The Animas Gold Medal water is special precisely because anglers protect it, the artificial-only, high-minimum rules keep the wild trout population strong, so handle these fish like the resource they are: barbless hooks make release easy, keep the fish wet, support them gently, and let them recover before swimming off. The same care applies to the native cutthroat in the high country, which are a treasure worth protecting. Fish the regulations, take only what you'll eat from the stocked lakes, and the San Juans will keep producing for the next angler.
Gear: Fly and Spin
- Fly: a 9-foot 5-weight (Orvis Clearwater 5wt), floating line, 9-foot 5X leaders (plus 6X–7X for the San Juan), strike indicators, split shot, and nymphs (Pat's Rubber Legs, Pheasant Tail, Zebra Midge, RS2), dries (Parachute Adams, Elk Hair Caddis, hoppers), and Woolly Buggers.
- Spin: a light 6-to-7-foot rod, a 2500-size reel, 6-pound line, Panther Martin and Rooster Tail spinners and small spoons; add Berkley PowerBait for the lakes.
- Lakes: trolling spoons and a Mack's Lure Wedding Ring for trout and kokanee.
- Bring layers (mountain weather swings fast), sun protection at altitude, and Simms Freestone waders for the rivers.
When to Go
- Late June–September: Prime time. The Animas clears after runoff, summer hatches and hopper fishing are excellent, and the lakes and high country are all in play.
- Fall (October): Outstanding, aggressive pre-spawn browns, blue-winged olive hatches, golden aspens, and fewer crowds.
- Spring (April–early June): The San Juan tailwater fishes great while the Animas is high with runoff; lakes ice off and turn on.
- Winter: The San Juan and tailwaters produce on midges; the Animas is cold and slow. A good time for the New Mexico day trip.
A First-Timer's Plan
For your first Durango trip in summer or fall, book a guided day on the Animas Gold Medal water, the guide supplies rods, flies, and waders, teaches you to read the river, and times it to the post-runoff window. Want easy action or fishing with kids? Soak PowerBait at Lemon Reservoir or fish a spinner in the high country. If you're up for a technical bucket-list day, plan the San Juan tailwater with a New Mexico license and a guide. Buy your Colorado license online first, and remember the Gold Medal stretch is artificial-only.
