If the school bell is ringing, the parks are clearing out. Early fall is an excellent time to visit Yellowsone, located in the northwest corner of Wyoming. The trees begin to change color, the elk start bulging, and many of the summer services are still open. Snow has yet to close roads and passes. The air is crisp, and the animals return to the valley from their summer mountain escapes. Here are the top reasons to visit Yellowstone in September.
Should You Visit Yellowstone in September?
I’ve been to over 100 National Park Service sites over the years, and Yellowstone is still my favorite. Early Fall is an excellent time to visit.
However, keep in mind that some of the lodging and services close on Labor Day Weekend, right after the summer season ends. For wildlife viewing, fall is particularly active as many species enter their mating season.

Top Things to See at Mammoth Hot Springs
The Mammoth Hot Springs area is open year-round. Due to its lower elevation, the roads are easier to keep open, and it is accessible through the North Entrance. With close proximity to Bozeman, Montana, and its large airport, many visitors use the North Entrance. Home to Mammoth Hot Springs and Fort Yellowstone, this area is a must for a Yellowstone National Park trip. From its visitor center to the hot springs, here are the top things to see at Mammoth Hot Springs.

Mammoth Hot Springs Terraces
One of the top things to see at Mammoth Hot Springs is the most protected travertine-depositing hot springs in the world. Best of all, visitors can explore the terraced hot springs to see all the hot water action.
Visitors can climb the different levels of the terraced limestone through a series of boardwalks and overlooks. Starting either at the top (accessible by car) or the bottom, visitors can hike the Mammoth Hot Spring Trail.
Divided into the Upper and Lower Terraces, the boardwalk features a series of stairs to view all the limestone features. There is one trailhead for the Upper Terraces and three trailheads for the Lower Terraces.
Runoff water seeps into the fractures in the ground, where it is heated by a volcanic source. It then bubbles back up to the surface at Mammoth Hot Springs, depositing limestone as travertine.
Like many of Yellowstone’s geothermal areas, the water is hot (over 160F) and visitors need to stay on boardwalks. Visitors need to practice Leave No Trace principles and refrain from throwing anything into Mammoth Hot Springs.

An add-on to the Mammoth Hot Springs Trail, it’s a .3-mile in-and-out trail with a 29-foot elevation gain. Find the trailhead along Grand Loop Road and its parking lots, and it’s the same area as the trailhead for Beaver Ponds Loop.
Opal Terrace
Located basically in the backyard of a historic 1908 house designed by Robert Reamer. It is located across the street from Mammoth Hot Springs Terrace.
Mammoth Terraces
If you hike the entire Mammoth Terraces Loop, it’s a 2.2-mile boardwalk with a 324-foot elevation gain, via stairs. It offers several trailheads along Grand Loop Road in the Mammoth Hot Springs Road.
Beaver Ponds Loop
It’s a moderate 5.5-mile loop with a 764-foot elevation gain. Find the trailhead at Grand Loop Road and its parking lots near Palette Spring Trailhead.
Bunsen Peak
This is a moderate peak hike closest to Mammoth Hot Springs. It is named after the inventor of the Bunsen Burner, who also studied geysers. It’s a 4.4-mile in-and-out trail with a 1,282-foot elevation gain.

Scenic Drives at Mammoth Hot Springs
Upper Terrace Drive
This 1.5-mile one-way drive winds through the features of the upper terrace. It is a great alternative for those who don’t want to hike the boardwalks on Mammoth Hot Springs.
Fort Yellowstone
As the park’s headquarters, this area offers more than the Mammoth Hot Springs. In Yellowstone National Park’s first few decades, the U.S. Army patrolled the park, securing it from poachers and rogue campgrounds.
The U.S. Army was stationed at Yellowstone National Park for 32 years. In 1891, the U.S. Army constructed Fort Yellowstone.
From the 1890s to the early 1900s, 35 structures remain from the U.S. Army occupation. It is a National Historic Landmark District, and the buildings still sport their red clay roofs.
For travelers interested in touring Fort Yellowstone, walk up Officers Row Road. Many of the buildings are in use, so stay on the street.

Yellowstone’s Wildlife in September
Who doesn’t love a luxurious grass lawn? The park’s elk frequently munch on grass in front of the hotel and visitor center. When not wandering the streets of Fort Yellowstone, the elk retreat to the bluffs above the Mammoth Hot Springs.
Since the National Park Service considers the grass a historic lawn, it is irrigated. The elk can be spotted sitting like cattle, nibbling its tender green blades.
During the fall season, the elk enter their mating season, named the Elk Rut. The males bulge and can be aggressive, so keep at least 25 feet away from elk.
The bears also retreat from their summer mountain retreats in the park’s higher elevations. Birds will also start their migration during September.
Wildlife in Yellowstone National Park
I recommend Hayden Valley or Lamar Valley along the river for the best wildlife spotting. The best times to spot animals are dawn and dusk, when they are most active. Check in with the Park Rangers, who know where animals frequent, or take a guided tour.
Bison
Moose
Elk
Grizzly Bear
Black Bear
Wolf
Bighorn Sheep
Mule Deer
Coyote
Pronghorn
Pika
Marmot
Note:
Stay at least 25 feet away from elk, bison, and other wildlife. For bears and wolves, stay 100 yards away.

Kids and Pets at Yellowstone National Park
Traveling with your kids or pets is part of the fun. Yellowstone makes a great trip with lots of activities and things to see.
There are special activities for kids in Yellowstone and it features a Junior Ranger Station open during the summer. As for pets, Yellowstone is a haven for wildlife, so care must be taken when traveling with your pets in the park.
Kids at Yellowstone
The Junior Ranger Program is the go-to program for families to learn more about a National Park Service site. It’s free and takes about two hours to complete. My kids love the badges the Rangers present them with after they complete their booklet.
Kids love Yellowstone and animals, so buy a Junior Ranger booklet at the nearest bookstore. In Yellowstone, the booklets are $3, but kids who complete them get a badge.
Yellowstone National Park divides the Junior Ranger booklet into three age categories with age-appropriate activities. Kids 4 to 7, 8 to 12 and 13 and older each complete as many activities as their age.
Try to turn in your Junior Ranger booklet at Yellowstone National Park’s Junior Ranger Station, located near the Madison entrance on the west side of the park.
Old Faithful Visitor Education Center also offers a Young Scientist Patch Program. Buy the $5 booklet at the visitor center’s gift store. The visitor center also checks out a pack of equipment needed to conduct experiments. This program is best suited for students spending a couple of days in the Old Faithful Area to finish.
Pets in Yellowstone
Some National Parks offer a BARK ranger badge for traveling pets. However, due to the rugged nature, including lots of wildlife, Yellowstone is not the best park for pets.
Many of Yellowstone’s wildlife are predators. Coyotes, wolves and bears consider pets a food source. Because of this, pets are not allowed on trails, boardwalks or in the backcountry.
Pets are allowed in developed areas and must remain within 100 feet (30.5 meters) of roads, parking areas, and campgrounds as long as they are with people. They must be leashed at all times and not left unattended inside the park. It is for their safety and more information can be found on the Pets page of the Yellowstone National Park website.

History of Yellowstone National Park
On March 1, 1872, Yellowstone National Park became the first national park in the world, an idea that has flourished worldwide.
Yellowstone’s significance began long before. Approximately two million years ago, a supervolcano erupted in Yellowstone, forming a caldera, or basin. It is located in the center of Yellowstone National Park and measures 45 miles across. It is now home to the largest concentration of geysers in the world.
The railroad arrived at the northern edge of the park in 1883. Then, the first roads started to bisect the park, allowing visitors more access to the geothermal features and animals. More people meant more buildings, with Lake Yellowstone Hotel and Old Faithful Inn a few of the surviving early lodges.
It was on the western frontier so the U.S. Army built a fort to keep the law and chase away the poachers.
