San Juan Worm - Red

The San Juan Worm – Red is a legendary and simple fly pattern that continues to deliver big results, especially in tough conditions. Designed to imitate aquatic worms and annelids dislodged during runoff, high water, or after rainstorms, this pattern is incredibly effective in both rivers and stillwaters. The bright red coloration makes it easy for fish to spot in murky water and serves as an excellent attractor pattern when trout are opportunistically feeding near the bottom.

Tied with a single piece of soft chenille on a curved hook, the San Juan Worm offers natural movement and a lifelike silhouette that trout simply can’t resist. Its subtle action and highly visible color allow it to stand out even in stained or fast-moving water.

To fish the Red San Juan Worm effectively, dead drift it under an indicator, tight-line nymph it in heavy seams, or use it as the anchor fly in a two-fly rig. It excels during runoff, following storms, or in tailwaters where aquatic worms are a major food source year-round. It’s a staple pattern that belongs in every angler’s fly box.
