Mount Rainier National Park during the summer is a wonderful opportunity to see a diverse range of wildlife, beautiful wildflowers, and breathtaking mountain vistas. However, if want to experience the stunning autumn foliage, then Mt Rainier in September or October is your best bet.

With an elevation of 14,411 feet, Mount Rainier reigns as the highest summit in Washington state. Its commanding presence can be seen from as far away as Seattle, but personally, I find the most spectacular and awe-inspiring views are those experienced in person and up close.

I’ve lived in Washington State for well over a few decades and have visited Mount Rainier numerous times and in all seasons. September is one of my favorites, for the flowers, the animals, the fall foliage and of course, the mountain itself.

Know Before You Go
*Check weather, road closures, and trail conditions.
*Purchase timed entry reservations between May 24 and Sept 2
*Bring a National Park Pass.
*Bring your own food, water and layers.

Mount Rainier in September

September is a beautiful time of change at the park, so what you see will varies depending on when in September you go and the prevailing weather conditions. Wildflowers are disappearing and fall colors are starting to pop. And it is always amazing.

Mount Rainier National Park is famous for its beautiful wildflowers. Some of the most common wildflowers found in the park include the purple lupine, fire-red paintbrush, charming avalanche lilies early in the season, the treasured trillium, and of course the delightful bear grass.

While wildflowers normally peak from late June through August, you may see them even into early September, depending on the weather. Particularly those years with heavy snow the previous winter.

Be sure to check trip reports before heading out however, if wildflowers is what you’re looking for. As mentioned earlier, they tend to peak earlier in the year and it’s only occasionally that you’ll see them all the way into September.

Wildflowers are found in different areas of the park depending on the season, elevation, and weather conditions. For example, wildflowers at lower elevations tend to bloom earlier in the year, while those at higher elevations bloom later in the summer.

If the previous winter brought significant amounts of snow, you’ll often see the early species blooming right alongside the late blooming species.

There are many places at Mount Rainier to see wildflowers and spend time in nature, depending on your mobility, time and energy. 

Reflection Lake

Viewing wildflowers here is simply a short walk along the lakeside trail.  In addition to the breathtaking wildflower displays, the postcard-perfect view of Mount Rainier reflecting off the lake is a must-see if cloud cover allows for it.

Myrtle Falls

Myrtle Falls is a relatively short and easy, mostly paved trail leading to a gorgeous waterfall, with a beautiful backdrop of wildflowers along the creek, if your timing is right. It’s less than a mile from the Paradise Visitor Center.

Sheep Lake

The Sheep Lake hike begins at Chinook Pass and gradually moves eastward towards the lake. As you make your way to the lake, look for Indian paintbrush and false hellebore. You may also see the delightful Western pasqueflower and smell the sweet valerian along your way.

Nisqually Vista Trail

The Nisqually Vista trail is also an easy and relatively short trail, just over a mile, through wildflowers to some magnificent mountain views. It’s also accessed directly from the Paradise parking lot.

Silver Forest Trail

For a slightly quieter but also easy hike you can choose the Silver Forest Trail near Greenwater and the Sunrise Visitor Center. This is a family friendly hike of about 2.5 miles, which takes you through a charming meadow of gorgeous wildflowers.

High Rock Lookout Trail

The High Rock Lookout Trail, near Ashford, is a 3.2 mile round-trip and moderate climb along a charming path bound by wildflowers on either side.

The hike ends at a newly refurbished fire lookout with a truly amazing view of Mount Rainier.  Please note that this is not a place for young children to run around freely, as there are many steep drop-offs.

Crystal Mountain

If you’re looking for nearly hidden gems at the park, you can take the gondola up to the top of Crystal Mountain and walk downhill through fields and fields of wildflowers.

While all downhill, it’s a somewhat long hike with many beautiful distractions along the way. The types of wildflowers change as you descend, so there’s always something delightful around every corner.

Grand Park

Grand Park, one of the park’s most impressive meadows, is a stunning plateau of wildflowers interspersed with silver snags and a breathtaking view of Mount Rainier.

There are two approaches to Grand Park, one that is longer and more difficult and one in which the road is steep and narrow, requiring a 4WD.  Be sure to check the park website for updated road conditions and closures.

Is September a good time for hiking and climbing?

September is a great time for hiking on Mt. Rainier. The summer crowds have diminished, and the weather, while cooler, is often stable in the early part of the month.

However, snow and ice can start appearing on trails, especially at higher elevations.

For climbing to the summit, September is typically the tail end of the climbing season. The routes are more challenging due to the icy conditions and crevasses are more open and exposed, so it’s recommended only for experienced climbers.

Viewing Wildlife at Mt Rainier

Marmot at Mt Rainier

Summer through fall is the best time to see wildlife at Mount Rainier. Look out for pikas, marmots, deer, mountain goats and black bears.  The best time to see wildlife is in the early morning and late evening, and on weekdays when there are fewer people about.

While there are coyotes, fox, cougars and even moose at Mt Rainier, you’re less likely to see them during your visit.


Pikas are small, herbivorous and adorable mammals belonging to the Ochotonidae family. They’re also commonly known as rock rabbits, coneys, or whistling hares. Pikas are known for their distinctive high-pitched and charming alarm call, which they use to warn others of predators.

They are roughly the size of a guinea pig, with short ears and legs, and dense fur that helps them survive in cold mountain environments.


Marmots are large ground squirrels belonging to the genus Marmota. They are known for their stout bodies, powerful limbs, and thick fur, which helps them survive in harsh alpine environments.

They hibernate during the winter months, often in large colonies, and emerge in the spring to mate and forage for food. Marmots are herbivorous and primarily eat grasses, flowers, and other plant material.

They are also known for their distinctive warning call, which sounds like a piercing whistle and is used to alert others in the colony of potential predators. You will likely hear them before you see them, as they blend in rather well.

Marmots make the hike, for me. Fortunately you’ll likely see at least one of them on your hike. Especially in September. They blend in rather well however, so listen for their calls and watch for movement in the brush.


Mount Rainier National Park is home to two common species of deer, including mule deer and black-tailed deer. Mule deer are most common on the eastern side of the park, while the black-tailed deer are more common on the western side.

The two species look very similar to each other. They’re both known for their agility, speed, and keen senses, which help them to avoid predators. You will often find them grazing in meadows or wandering through forests in the early morning.

Mountain goats

Mountain goats can be found in the subalpine and alpine meadows, rocky slopes, and cliffs of Rainier. One of the most popular places to observe mountain goats in the park is be exploring around the the Sunrise Visitor Center.

The hikes at Sunrise tend to offer excellent opportunities for viewing mountain goats in their natural habitat. Remember to observe mountain goats from a safe distance and to avoid approaching them, as they are wild animals and can be dangerous if provoked.


Black bears are commonly spotted throughout Rainier National Park. While some bears may look cinnamon or brown in color, these are also black bears. There are not any grizzly bears at Mount Rainier National Park.

Where to See Wildlife at Rainier

Sunrise visitor center has some easier hikes where wildlife are often seen, particularly the Sunrise Nature Trail and Frozen Lake via Sourdough Ridge Trail. Be sure to keep your distance, for your own safety.

The paths around the visitor center at Paradise also have many animal sightings, throughout the summer and fall months. While you are likely to see marmots on nearly every trail, fox and deer are often seen at Narada Falls in particular.

You can hike Naches Peak Loop or many other trails that have plenty of wildlife, particularly in the early morning hours. And the Elk Creek Wildlife Feeding Area is just west of Naches, is a great place to see elk during those same hours.
