Fly Fishing Puget Sound Beaches for Sea-Run Cutthroat

There’s something special about chasing sea‑run cutthroat trout from the beaches of the Pacific Northwest. These wild fish are available year‑round, they’re aggressive, and they thrive in the saltwater environment just a short drive from home.

Starting out in this fishery doesn’t require a mountain of gear, but a few key pieces can make all the difference. A fast 6‑weight fly rod paired with a saltwater‑safe reel is the standard setup, giving you enough backbone to cast into the wind while still being light enough for long sessions. Lines are equally important: an intermediate sinking line is the workhorse for most situations, cutting through surface chop and keeping your fly in the strike zone, while a floating line shines when you want to fish surface flies like poppers or gurglers, or when you want to fish just subsurface in the shallows. A stripping basket is essential, especially when using a sinking line—without one, your line will tangle in seaweed or get dragged by the surf, and you’ll spend more time fighting your line than fishing.

Leader setups are straightforward. On a sinking line, a 4–7 foot fluorocarbon leader is a great place to start. I usually build mine with about a foot and a half of 20‑pound, another foot and a half to two feet of 15‑pound, and then two to three feet of 2X fluorocarbon tippet, all connected with blood knots. On a floating line, especially when fishing poppers or gurglers, a simple 9‑foot nylon leader in 2X or 1X is perfect. These fish are not line‑shy, so durability and turnover matter more than delicacy.

Approaching the beach is part of the fun. Don’t rush into the water—many cutthroat cruise right along the shoreline, so start by fishing shallow and close. From there, fan‑cast to cover water methodically, taking a few steps between casts to work down the beach. These fish are wanderers, and by moving steadily you increase your odds of intercepting them. Pay attention to the conditions: tide changes are critical because moving water concentrates bait and triggers feeding. Outgoing tides often fish well, but every beach has its own personality. Wind is another factor—fish in conditions you can cast comfortably, and remember that a little chop can actually make the fishing better.

Not all beaches are created equal, and knowing which ones to target makes a huge difference. Shellfish beaches are prime spots because they attract forage and create natural feeding lanes. Rocky beaches with lots of structure are excellent too, giving cutthroat places to ambush baitfish and providing cover. Eelgrass beds are another favorite—these underwater meadows are alive with shrimp, baitfish, and other food sources, making them magnets for hungry trout. Also, look for creek mouths where the cutthroat will travel up to spawn or wait for salmon smolt and other food sources to pour out. When scouting new water, keep these features in mind; they’re often the difference between a slow day and a memorable one. Some great beaches to try when you’re getting started include Potlatch State Park, Anderson Point, Meadowdale Beach Park, and Purdy Spit. I’ve personally had success at each of these beaches, and they all offer easy access for anyone beginning to chase these fish.

Flies for sea‑run cutthroat are wonderfully varied. Small baitfish patterns are staples, imitating sand lance, herring, smelt, salmon fry, or sculpins. Euphausiid and shrimp patterns shine in winter, while small leech patterns can be deadly year‑round. Surface flies like poppers and gurglers provide explosive takes that you’ll never forget. Some of our favorites that we carry are the Baitfish Minnow, Deception, and the Skinny Herring. Don’t be afraid to try something different—these are aggressive, feeding fish!

Fishing technique is simple but nuanced. Cast as far as you can (start practicing your double‑haul!), but don’t forget to fish the water close to you. If you’re using a sinking line, give it a few seconds to reach the desired depth before starting your retrieve. Vary your strip speed and length—sometimes the fish want long, slow pulls, other times short, fast strips with pauses, and occasionally they’ll chase a fly stripped back as fast as you can manage. Experimentation is the key to unlocking their mood on any given day.

Finally, remember the rules and ethics of this fishery. Barbless hooks are required, catch‑and‑release is the standard, and handling should be minimal. Wet your hands before touching a fish, keep them in the water as much as possible, and release them quickly. These trout are resilient, but they deserve respect.

Sea‑run cutthroat beach fishing is a blend of simplicity and nuance, offering endless opportunities to learn and refine your approach. With the right gear, a thoughtful strategy, an eye for productive beach types, and a respect for the fish, you’ll find yourself immersed in one of the most rewarding fisheries the Pacific Northwest has to offer.
