Where to park

Lair o' the Bear Trailhead

  • 22550 CO-74, west of Morrison. Free. The main lot fills early, often before 9 a.m. on sunny weekends.
  • If it's full, try O'Fallon Park or Corwina Park just up the road rather than parking illegally.

Lots, fees and hours change. Check posted signs when you arrive.

Overview

Bear Creek is a small canyon creek full of wild brown trout, close enough for an evening session. Most anglers start at Lair o' the Bear Park near Idledale, where a trail follows the creek. It gets busy with hikers and picnickers on weekend afternoons, so go early.

Where to fish

Flies and tactics

In summer the browns aren't picky: an attractor dry or caddis (#14–16) gets eaten. In winter, fish midges and small nymphs in the slow pockets, plunge pools and tailouts during the warmest part of the day. Hip waders are plenty.

Respect the creek

Low flows concentrate fish in a few pools. If you find them stacked up, fish lightly and move on. Much of the upper creek is private, so stay within posted public access.
