Trail Tips

Choose Wading Boots with Grip

Pack a Versatile Fly Box

Insect hatches can vary daily; having a variety of dry and wet flies improves your chances of enticing a bite in changing conditions.

Start Early to Beat the Heat

Fly Fishing the Au Sable: Classic Waters in the Heart of Trout Country

The Au Sable River in Michigan is more than water winding through the forest—it's a living challenge, daring anglers to match wits with its native trout. Known as one of the premier fly fishing destinations in the Midwest, the Au Sable flows with a steady pulse, its currents pushing forward with purpose, carrying trout that are both wary and eager to test your skill. The river's clear, cool waters thread through hardwood forests and rocky bluffs, offering fishing spots that balance accessibility with the thrill of discovery.

Start your day early when the sun begins to lace the water with light. The morning calm is your ally, and hoppers and dry flies dance on the surface like tempting invitations. Sections such as the South Branch and the Gorge provide varying currents where trout gather—either tucked in tight under overhangs or cruising the riffles. The Au Sable rewards anglers who are patient, observant, and ready to adapt.

Navigating the riverbanks is practical work: expect uneven terrain dotted with roots and rocks, so solid footwear is a must. Wading boots with good ankle support will help you negotiate slippery stones and shifting gravel bars. Hydration is key, especially in summer, as the exertion of casting combined with sun can drain your energy more quickly than expected.

Timing matters on the Au Sable. Late spring and early summer present rising insect hatches, coaxing exciting dry fly action. Fall brings cooler water and hungry trout preparing for winter, accompanied by vibrant foliage framing the river’s bends. Winter changes the game—ice edges and slower flows require heavier gear and greater caution.

Beyond fishing, the surrounding forest breathes alongside you. Birdsong threads through tall pines, and the rustle of leaves is a steady companion. The Au Sable isn’t just a river to fish; it’s a force to engage with—fierce in its own rhythm, respectful when treated wisely.

Plan your trip with clear shoes, a versatile fly box, and layered clothing that responds to sudden shifts in weather. Local guides and fly shops in nearby towns provide up-to-date river conditions, flies, and insider tips that can elevate your experience. Fly fishing the Au Sable is a practical adventure grounded in understanding the water’s mood and the trout’s habits. It’s a day on the river that demands attention, rewards effort, and leaves you connected to one of Michigan’s finest natural treasures.
