Yellowstone River (YNP) - Summer Fly Box

Fish the Yellowstone like you know it — because now you do.

The Yellowstone River Summer Fly Box is hand-curated specifically for the conditions, hatches, and trout behavior you'll encounter on the Yellowstone inside Yellowstone National Park from July through August. By early July the river drops and clears, the Salmonflies come off, and willing Yellowstone Cutthroat start rising everywhere you look. This is why people drive from across the country.

This box is built around the Yellowstone's summer hatch calendar — Salmonflies, PMDs, Caddis, hoppers, beetles, and ants. Every fly was chosen with fishing the foam lines during Salmonfly season and matching the terrestrial bite through August in mind, giving you exactly what you need to match what the fish are eating at this time of year.

What's in the box:

36 flies total — 18 unique patterns, 2 of each — covering Salmonfly dries, PMD patterns, Elk Hair Caddis, Chernobyl Ants, hopper patterns, and summer nymphs. No filler. No patterns that don't belong on this river in this season.

Pro tip from the water: Fish the foam lines. Cutthroat on the Yellowstone love to stack on bubble lines during Salmonfly season — dead drift a big dry right through the foam and hold on.

Whether you're making your first trip to the Yellowstone or you fish it every season, this box gives you a proven starting lineup so you can spend more time fishing and less time digging through bins at the fly shop.

Includes a quality waterproof fly box. All flies are hand-tied to Bozeman FlyWorks standards — the same quality we'd put on our own lines.
