When in Rome, do as the Romans do. And when in Mt. Rainier National Park, do whatever the rangers tell you—and stay on the path!! With this in mind, we consulted our go-to Mt. Rainier expert Terry Wildy for her fall season recs. As Chief of Education, Interpretation, and Volunteers, Wildy has never steered us wrong.

So, the autumn is probably off-season, right? You don’t even need timed entry reservations after Sept. 1, so why plan ahead? Actually, this time of year is stunning at the park, and word is getting out. “The fall hiking season at Mount Rainier National Park has become very popular,” said Wildy. “Visitation last October was the highest we have seen in years; weekend crowding was as intense as a summer weekend.”

But keep those hiking boots on, friend. This guide will help you enjoy the best of the season at Mt. Rainier, offer tips to avoid crowds, and teach you to visit thoughtfully and safely (hint: you might encounter bears!). 

 

Part I: Fall may be getting popular, but it’s still considered the off season.

Mt. Rainier has a zealous visitor base during the summer and a bit more devoted crowd in the winter. Visitation in the fall is very weather-dependent, and more limited in activities. It’s too early for snowshoeing, but certain hiking paths and businesses may not be open with summer’s end. Check to make sure your destination is open and accessible this time of year!

Some considerations: 

  • Timed Entry Reservations are no longer required after September 1. 
  • Snow typically shows up in October but can start as early as September.
  • Construction work is ongoing. A 2.8 mile section of SR 123 will be completely closed between September 2-30, 2025.
  • Visit the National Park Service website for the latest info about road and entrance closures.
  • The Nisqually Entrance is the only entrance open year-round. 
  • As of 2025, the Carbon River / Fairfax Bridge is closed for the near future. 
  • Is gorgeous sunshine in the October forecast? Try for a weekday to avoid crowds.

 

As long as the snow stays at bay, most businesses in the region stay open. Did snow come early? We love these winter spots:

 

Part II: Weather will happen. Be prepared!

Prepare Yourself

In addition to the typical 10 essentials, make sure you have some comfortable layers in case warm sunshine suddenly gives way to a chill; this time of year, weather changes on short notice. 

Prepare Your Vehicle

As mentioned above, snow is a possibility as soon as September. Between November 1 and May 1, all vehicles in Mount Rainier National Park are required to carry tire chains or some sort of traction devices, but you may want to pack some just in case.

 

Part III: The ultimate autumn activity guide

Now that you’re informed, prepared, and packed, let’s get into the fun stuff. 

Look down, not up, for autumn colors!

Many of the trees are evergreen and don’t change with the season, but vine maples, Sitka mountain ash, and huckleberry bushes all turn vibrant red and gold at high elevation. Though these stunning views are enticing, we implore you once again to stay on the path. 

Terry Wildy puts it well. “We saw an abundance of inappropriate instagram posts and photos on all social media platforms that unfortunately seemed to encourage off trail selfies. We love to see folks out enjoying their public lands, but again our messaging is to stay on the trail.”

Hiking

So long as the weather cooperates, there’s no reason you can’t enjoy the most popular hiking destinations with much less traffic, particularly if you visit on a weekday. A couple of our favorites: 

  • Skyline Trail Loop has a long season and manages to incorporate meadows, waterfalls, and of course, stunning views of the mountain all in a 5.5 mile loop.

  • Alta Vista Loop is a great option if you’re chasing the fall foliage more than the hike itself. At just 1.5 miles, this loop is painfully busy during the wildflower season, but could be your autumnal oasis on a Wednesday afternoon.

Wildy is enthusiastic for you: “Fall hiking can be very enjoyable; the days are shorter but the temperatures are cooler, and especially on weekdays there tend to be smaller crowds.”

Watch (out for!) the animals

This time of year, black bear families are gobbling huckleberries to put on as much weight as possible before winter. Depending on your inclination, this could be a drawback or a plus. So long as you keep your distance and never get between a mother and her cubs, black bears are generally safe—but your hike may be extended as you wait for them to pass. 

“Sometimes folks have to wait patiently on the trail for an hour for a bear to move along to the next tasty huckleberry shrub,” explains Wildy. “Understand that bears always have the right of way on trails.” 

You can learn more about wildlife safety here, including what to do if you encounter a mountain lion. 

That’s it! Pack well, check conditions ahead of your arrival, and most importantly—say it with us!—STICK TO THE PATH. In fact, you have our express permission to send this article to anyone on social media posting from the middle of a Mt. Rainier meadow, regardless of the season. 

Wildy wishes you well too. “Enjoy some of the best hiking weather and most beautiful scenery Mount Rainier National Park has to offer!”
