2026 regulation year

Rocky Mountain National Park Fishing License 2026

Last updated

Colorado

Rocky Mountain runs on the host state's fishing license; the National Park Service does not sell a separate permit here.

Quick answer

State fishing license applies

A valid Colorado fishing licence is REQUIRED for anyone 16 or older. Colorado Parks & Wildlife regulations control season and possession, with park-specific overlays on tackle (one rod only, single-hook artificial flies and lures, barbless on catch-and-release waters), a published closed-waters list, and a native-trout-conservation possession schedule.

What to know before you fish Rocky Mountain

  • Licences and the Habitat Stamp: buy from CPW agents statewide, online, or by phone (1-800-244-5613); residents and non-residents both required at 16. Individuals over 18 and under 65 must pay the $10 Habitat Stamp with their first licence of the year. The Colorado Second Rod Stamp is NOT honored in park waters — one rod only — regardless of state-side privileges.
  • Tackle restrictions: only artificial flies or lures with one hook (single, double, or treble on a common shank) may be used in park waters. Fly fishers may run a two-hook system with one hook as an attractant. In waters designated catch-and-release, barbless hooks are mandatory. Children 12 and under may use worms or preserved fish eggs in any park water open to fishing and not designated catch-and-release — bait of any kind is prohibited in catch-and-release waters. Use of lead sinkers or other lead fishing materials is strongly discouraged.
  • Possession schedule (native-trout-protection design): no more than 18 trout in possession at any time, in one of two combinations — 18 brook trout (8 any size, the remaining 10 must be 8 inches or less) OR 16 brook trout (6 any size, 10 must be 8 inches or less) plus 2 additional trout 10 inches or longer (which may include rainbow, brown, or cutthroat). The schedule is built around restoring native Colorado River and Yellowstone cutthroat populations the park has been actively recovering since the 1970s.
  • Closed-waters list (no fishing): Bear Lake (including 200 yards up- and downstream of inlet/outlet), Fern Creek (Fern Lake outlet down to The Pool), Hague Creek (above the Mummy Pass Creek junction), Kettle Tarn, Lake Nanita (outlet to 100 yards downstream), Shadow Mountain Reservoir below the spillway to the southern park boundary including Columbine Bay (Oct 1 – Dec 31), South Fork of the Cache la Poudre above Pingree Park, and Upper Columbine Creek above 9,000 ft (barrier-marked). All creeks and rivers not on the closed list or the catch-and-release list default to catch-and-keep under the possession schedule.
  • Aquatic-invasive prevention: park fish are vulnerable to whirling disease, New Zealand mudsnails, and other invasives carried on waders, boats, and tackle. NPS Rocky publishes a Disinfection Guidelines document anglers are expected to read and follow before fishing the park's waters; cross-drainage gear transfer is the main vector the park is trying to interrupt.

How licensing works at Rocky Mountain

Rocky Mountain National Park runs on the host state's regular fishing license — there is no separate National Park Service fishing permit to buy. Use the same Colorado license you would use anywhere else in the state. Park-specific regulations (gear restrictions, species closures, catch-and-release zones) still layer on top of the state rule, so read the unit's current fishing page before launching.

On federal land, in-season closures don't go through the host state's DFW — they post to the unit's own news desk. Road closures that cut off river access, wildfire trailhead shutdowns, drought-driven access changes, and bear-activity lake closures all publish to Rocky Mountain's National Park Service news feed.
