Route Schematic
Typical itinerary schematic
A full-day itinerary moves between prime trout waters and includes a midday break for lunch.
High-country waters — Rocky Mountain National Park
Fish stretches within or near Rocky Mountain National Park where guides target high-elevation runs and pockets ideal for dry- and nymph-fishing.
Valley river — Blue River at Silverthorne
The Blue River at Silverthorne offers a contrasting river environment; guides may take the group here for a different set of flows and holding lies.
Alternate rivers — Big Thompson or Boulder Creek
Some full-day trips split time between two locations, such as the Big Thompson River and Boulder Creek, to vary the fishing and maximize opportunities.
Riverside lunch and mid-day regroup
Full days include a provided lunch—typically taken riverside—to rest, refuel and discuss tactics before the afternoon session.
Operators may change specific waters or the day’s route according to conditions; anglers must carry a valid Colorado fishing license and be prepared for a long, active day on uneven river terrain.
