Peak to Plains Guide Service is a Colorado fly-fishing outfitter based in Estes Park, offering guided experiences across Rocky Mountain National Park, local Estes Park waters, private fisheries, and the Front Range and eastern Plains. Its guides bring more than 20 years of experience across the state and share local knowledge with anglers of all skill levels, with a focus on respecting fish and their habitats.

Trips include walk-and-wade fishing on alpine streams and lakes in Rocky Mountain National Park, convenient outings near Estes Park, and guided access to private trout water about 45 minutes from Denver. For a change from trout, guests can book warmwater trips by boat on Front Range and eastern Plains reservoirs, as well as guided fishing on Horsetooth Reservoir. Depending on location, anglers may pursue wild trout, including rainbow, brown, brook, and cutthroat trout, or warmwater species such as wipers, bass, and carp. Listed trips generally run four to eight hours for trout outings and four to six hours for warmwater fishing, with prices starting at $275 for selected trips.
