Hiking Mt. Rainier Trip report Washington Cascades

Naches Peak Loop (Mt. Rainier) – 08/08/2025

For our final hike of our Mount Rainier vacation we landed on the Naches Peak Loop. This was originally not going to be our final hike but after several changes to our plans throughout the week it wound up here and we couldn’t be happier that it did. This was a spectacular hike with tons of wildflowers, great views, and a nice variety of wildlife.

Less than 40 minutes from Packwood we arrived at the trailhead a little before 5:45am.

The Naches Peak Loop Trail is 3.5-miles with 500′ of elevation gain. A portion of the loop follows the Pacific Crest Trail which provided an opportunity for a side trip down to Dewey Lakes in the William O. Douglas Wilderness.

It is recommended to hike the loop clockwise to maximize the views of Mount Rainier so that was our plan as we set off. The wildflower display was immediately profuse.

The PCT was more level as it traversed the hillside below Naches Peak.

Just under a mile from Chinook Pass the PCT passes a small tarn below Naches Peak. We detoured around the tarn on a use trail.

We came to a junction 1.7-miles from Chinook Pass where the PCT forked left to head downhill to Dewey Lake.
IMG_9026

Heather decided not to make the side trip down to Dewey Lake as it added over 600′ of elevation gain, and over 3 miles to the hike. I headed down the PCT which made one big switchback then headed more directly toward the lakes.

I continued counterclockwise on the Naches Peak Loop. The wildflowers were not as thick on this side of Naches Peak, but the views of Mount Rainier were excellent.

With the detour to Dewey Lakes my hike wound up being 7.2-miles with roughly 1200′ of elevation gain.

This wound up being the perfect hike to end our trip with providing big views and extensive wildflower meadows along with a surprising variety of wildlife sightings. It was also short enough that we on our way back to Salem a little before 10am allowing us to be home mid-afternoon (no thanks to Portland traffic). It had been a great trip, even with the flat tire the first day. The temperatures had been especially welcome as it never got above 60 degrees Fahrenheit. It seems like it had been many years since our last summer vacation that didn’t include 90-to-100-degree temperatures at some point. We were also pleasantly surprised with how often we didn’t notice the crowds. While the park was busy there were times every day where we were able to enjoy a feeling of solitude, even in the Paradise Area. We weren’t in the park on a weekend so things might have felt differently on a Saturday, but our experience was very positive. I don’t know when we’ll be back, but there are still plenty of trails left for us to explore at Mount Rainier. Happy Trails!
