Operator Shop / Departure
Guides meet clients at the shop and provide transport from there to the river and back at the end of the day.
Long Dry-Fly Stretches
Fish long, slow, meandering water where trout commonly rise in pods and respond to small dry flies.
Nymph Runs and Deep Pools
Work beautiful nymph lanes and fish deep pools that hold larger specimens using tactics suited to subsurface feeding.
Riverside Lunch and Continued Fishing
The full-day includes a lunch break with soft drinks before finishing out productive water and returning to town.

Highlights
Outing Highlights
A Classic Dry-Fly Stream Through Town
The Big Horn flows right through Thermopolis with long stretches of slow, meandering water where fish often rise in pods—so prolific that a deep run can look like a shallow riffle—making it an ideal venue for dry-fly fishing.
Varied Water: Nymph Runs and Deep Pools
Beyond the dry-fly lanes, the river offers beautiful nymph runs and very deep pools that hold sizable fish, giving anglers a range of tactics to pursue memorable strikes.
A Full-Day Guided Experience
The full-day trip includes a boat with one to two clients, transportation to and from the river, lunch and soft drinks, rod and reel if needed, and required safety equipment so anglers can concentrate on fishing rather than logistics.
