Meadow closures, September 1 – October 31

From September 1 through October 31, parts of Horseshoe Park, Moraine Park, Upper Beaver Meadows, Harbison Meadow and Holzwarth Meadow are closed to foot travel off established roads and designated trails, and on closed roads or trails, from 5 p.m. to 10 a.m. daily. [NPS][NPS]

Fishing in the sections of Fall River, Big Thompson River and Colorado River inside those areas is closed in the evening and morning too. The NPS area-closures and elk pages give 5 p.m. to 7 a.m., but the Superintendent's Compendium gives 5 p.m. to 10 a.m. If you plan to fish, ask a ranger. [NPS][NPS][NPS]

The compendium's Moraine Park closure excludes Moraine Park Campground, but it includes the east–west trail from Mailbox Junction to the campground. The Horseshoe Park closure starts at the west edge of the Aspenglen Campground road. [NPS]

Elk-viewing rules

  • Stay at least 75 feet away, about two bus lengths. If the elk move away or their attention shifts, you're too close. Approaching wildlife is illegal in the park. [NPS]
  • Stay by the roadside when viewing elk in the park's meadows. [NPS]
  • Artificial lights and calls are illegal for viewing or attracting wildlife. That includes elk bugles, varmint calls, audio attractions, rattling antlers and verbal imitations. [NPS][NPS]
  • Popular elk-viewing spots include Moraine Park, Sheep Lakes, along Trail Ridge Road, Horseshoe Park and Harbison Meadow. [NPS]

Food storage still applies

Bears are active in the fall too. Park campgrounds require food lockers. Bears & food storage rules [NPS]
