Fishing Recommendations

Welcome to Big Hunting Creek, the crown jewel of Maryland fly fishing. Located in the Catoctin Mountains near Thurmont, this is a place of historic significance—it was the first stream in Maryland designated as "Fly Fishing Only" in the 1930s and has been fished by presidents (due to its proximity to Camp David).

As your guide, I’m going to break down how to tackle this technical, beautiful freestone stream.


🎣 Location Overview

Big Hunting Creek is a classic Appalachian freestone stream characterized by its plunge pools, massive boulders, and crystal-clear pocket water. It flows through Cunningham Falls State Park and Catoctin Mountain Park, offering a scenic, canopy-covered environment that feels much more remote than its proximity to D.C. and Baltimore suggests.

What makes it special is its character. This isn't a "drift boat" river; it is a "boots-on-the-ground" tactical challenge. The water is highly oxygenated by the constant drops, but the fish are notoriously "educated" due to the stream's popularity and the clarity of the water.

🪰 Recommended Flies & Techniques

Top Fly Patterns

  1. Dry Flies:
    • Elk Hair Caddis (Size 14-18) - The local staple.
    • Parachute Adams (Size 16-22) - Essential for picky fish.
    • Royal Wulff/Stimulator (Size 12-14) - Great for the faster, "bubbly" pocket water.
    • Terrestrials: Black foam ants and beetles (Size 16-18) are mandatory in summer.
  2. Nymphs:
    • Pheasant Tail (Size 18-20) - Beaded and non-beaded.
    • Zebra Midge (Size 20-22) - In red or black.
    • Copper John (Size 16-18) - For faster runs.
  3. Streamers:
    • Woolly Buggers (Size 10-12) in olive or black. Fish these deep in the larger pools below the falls.
