Wyoming Elk Rut 2026
Inside the published rut window now. Every date, place and distance below is quoted from the agency that published it, with the link. Wyoming publishes a minimum viewing distance of 25 yards, and this page quotes it in full.
Weather at Mammoth Hot Springs
Bugling is a dawn and dusk business, so the overnight low and the sky cover are the two things that decide whether standing in a meadow at six in the morning in Wyoming is worth it. This reads the National Weather Service forecast for this exact spot and shows you its own words.
When elk bugle in Wyoming
Wyoming: the rut window its agencies publish
September 1 to October 15midpoint September 22
Inside the published window now. No source names a peak date for this state, so the date above is our own midpoint of the published window and is labelled as such.
The mating season (rut) generally occurs from early September to mid-October.National Park Service, Yellowstone National Park. Read it on the source page
Read that as climatology, not as a forecast. The agencies are describing when the rut normally runs where they work, and a warm autumn or a hard early cold snap moves it. What does not move much is the shape: bulls are loudest for a few weeks, the noise tails off, and the animals go quiet and start moving to winter range.
The National Elk Refuge at Jackson is the famous Wyoming elk place and it is the wrong place in the rut. The Fish and Wildlife Service says elk are rarely observed on the refuge until mid November or early December and are typically visible from mid December through early April. It is a winter destination, and a September visit will show you an empty flat.
The elk of Wyoming
Continuously wild herd
Around a hundred thousand elk statewide, and the two most famous autumn viewing grounds in the country: the northern range of Yellowstone around Mammoth Hot Springs, where bulls bugle between park buildings, and the sage flats of Grand Teton.
Yellowstone provides summer range for an estimated 10,000–20,000 elk (Cervus canadensis) from six to seven herdsNational Park Service, Yellowstone National Park. Read it on the source page
Public places Wyoming’s own agencies send you
These are the sites the managing agency names on its own page, all of them on public ground.
Mammoth Hot Springs
National Park Service, Yellowstone National ParkThe northern range headquarters area, where the rutting bulls come right into the developed area among the old Fort Yellowstone buildings. The park names the northern range and Mammoth as its autumn rut viewing areas.

How far back to stand in Wyoming
A rutting bull elk weighs as much as a small car, is running on hormones and has antlers he is actively looking for something to fight. People are hurt by elk in the United States every autumn, usually while walking towards one with a phone held up. This is the one section of this site that is not about timing.
What the agencies themselves say about distance
These are quoted from the managing agency’s own page for that specific place. There is no single national elk distance; where two figures apply to the same ground, the larger one is the one to keep.
Always keep at least 25 yards (23 m), or the length of two full-sized buses, from elk.National Park Service, Yellowstone National Park, release dated August 27, 2024. Source page
Always stay at least 25 yards (75 feet) away from elk, moose, and bison, and 100 yards (300 feet) away from wolf and bear.National Park Service, Grand Teton National Park. Source page
The distances above are what the managing agencies publish, reproduced with their names on them. Where they differ, and they do differ by a factor of four across the country, the rule that applies to you is the one published by whoever manages the ground you are standing on.
Closures, roads and rules in Wyoming
Roads in the park remain open until November 1, however temporary closures may be put in place due to inclement weather.National Park Service, Grand Teton National Park. Read it on the source page
Dates for this year’s seasonal closures, guided tours and viewing programmes are set annually by the agency and published on the agency page linked above.
Where the Wyoming records actually are
This is the empirical half of the page, and it answers a different question from the dates above. The map is every verifiable iNaturalist record of Cervus canadensis drawn as a grid of counts, so it shows where in Wyoming people have actually recorded elk, updated whenever somebody uploads another one. It under draws roadless country and over draws parks and roadsides, because that is where the people are.
Coloured cells are verified Cervus canadensis records on iNaturalist, brighter where more have been logged. This is where people have found and photographed the species, so it thins out over roadless country and thickens around parks and towns. It is a record map, not a drawn range boundary. See the underlying records.
If you toggle that chart to the adjusted series it divides by every research grade observation of anything in Wyoming in the same month, which removes observer effort. In the big western states that correction pushes the peak into January and February, because elk come down to winter range where you can see them from a car and because almost nobody is recording anything else outdoors in a Rockies winter. That is a real pattern about elk and about people, and it is still not the rut. See the underlying Wyoming records on iNaturalist.
In October, Wyoming has historically produced 435 of those records.

Rut windows on this page are climatology published by the named agency, not a forecast, and MyWild adds no model of its own on top of them. Distances are quoted from the managing agency and are not this site’s advice. Live weather comes from api.weather.gov and is shown with the issuing office and the time it was generated. Nothing here should be read as a statement that approaching an elk is ever safe.
