Hiking The Portage Pass Trail in Whittier: Our Experiences
One of the best activities in Whittier is hiking, thanks to its breathtaking scenery. However, the weather in Whittier can be extremely unpredictable.
Chris and I have visited this city many times and attempted to hike the Portage Pass Trail on three different occasions. Unfortunately, our first two attempts were thwarted by the weather. The first time, relentless rain kept us off the trail for days. A thick fog rolled in during our next visit, so dense that we could barely see our feet. It felt like walking through a sea of milk with no port in sight.
Thankfully, our persistence paid off during our latest visit. We arrived in Whittier at the beginning of the season, in mid-May. The mountains were still blanketed in fresh, fluffy snow. We booked a camping in Whittier for a few nights, determined to finally complete our hike.
However, this hike can also be done as a day trip from Anchorage, so you don’t need to stay overnight in Whittier.


This time, luck was on our side. Despite the cold, the sun was shining brightly. We embarked on the Portage Pass hike, trudging through deep snow, which made the journey quite exhausting. But the stunning views more than made up for the effort. In the summer, when the snow has melted, this trail is much easier to navigate.
Below, we share our firsthand tips, observations, and photos from the Portage Pass Trail. Our experiences will help you plan your hike, ensuring you make the most of this beautiful trail. If you’re planning your trip, take a look at our Whitttier travel guide for a full overview of the best places and experiences.

Starting the Hike
The Portage Pass Trail begins at the trailhead in Whittier. It’s located in Chugach National Forest. From the moment you start, be ready for a workout. The trail starts with a steep ascent, climbing about 800 feet in the first 0.8 miles.
This part is rocky and can be challenging, but it offers stunning views of Passage Canal as you climb higher. Don’t forget to stop and take in the scenery as you catch your breath.
Reaching Portage Pass
At the top of the initial climb, you’ll reach Portage Pass. This spot offers an incredible view of Portage Glacier and the surrounding mountains. It’s a perfect place for a break and some photos.
The glacier’s blue ice and the lake below are breathtaking, especially on a clear day when you can see for miles. This viewpoint makes the climb well worth the effort.

Continuing to Portage Lake
From Portage Pass, you can continue hiking down to the shores of Portage Lake. This section of the trail is about 1.5 miles long and descends gradually.
The trail here is easier and less rocky, winding through alpine meadows and patches of wildflowers in the summer. You’ll also pass by Divide Lake, a small but picturesque lake along the way.

At the Shore of Portage Lake
Reaching the shore of Portage Lake is the highlight of the hike. You can walk right up to the water’s edge and marvel at the glacier from a different perspective. The lake, formed by the melting glacier, is serene and offers another great photo opportunity. This spot is ideal for a picnic or just relaxing and enjoying the view.

Returning to the Trailhead
After soaking in the views and perhaps having a picnic by the lake, you’ll retrace your steps back up to Portage Pass and then descend the steep trail back to the trailhead.
The return hike is quicker since you’re going downhill, but remember to watch your footing on the rocky terrain. The descent can be tough on the knees, so take your time and enjoy the changing views as you go.

History of the Portage Pass Trail
As a huge fan of Whittier’s history, I would like to share with you some of the existing information about this trail’s history. It’s a unique trail. Here is why:
The Portage Pass Trail is one of the oldest sections of the Iditarod National Historic Trail, steeped in a rich history that highlights its importance to various cultures and activities over the centuries.
Indigenous Use and Early Exploration
For centuries, Alaskan Native cultures, particularly the Alutiiq people (Sugpiaq), utilized the Portage Pass to access Passage Canal. This trail was crucial for trade and communication, linking coastal and interior regions and facilitating cultural exchanges.
Russian Traders and Exploration
In the 18th and early 19th centuries, Russian traders explored and used the Portage Pass. It served as a vital route for transporting goods and furs between settlements, integral to the Russian-American trade system. The trail’s strategic location made it essential for the economic activities of the time.

Gold Rush Era and Settlement
In the late 1800s, Portage Glacier still covered what is now Portage Lake. During this period, prospectors and settlers crossed the glacier ice to reach Turnagain Arm, driven by the promise of gold and new opportunities. The Portage Pass became a significant route during the gold rush, aiding in the movement of people and supplies.
Modern Development
The early 20th century saw significant changes with the construction of the Anton Anderson Memorial Tunnel by the U.S. Army. Completed in 1943, this tunnel connected Whittier to the Seward Highway and Anchorage, enhancing public access to the trail. Whittier’s development as a strategic military port during World War II further underscored the trail’s importance.
Today, the trail is maintained for recreational use, offering hikers a glimpse into Alaska’s rich natural and cultural history. The stunning views of Portage Glacier, Portage Lake, and the surrounding mountains continue to attract visitors from around the world.
Meaning of Portage
The term “portage” refers to the practice of carrying watercraft or cargo overland between two bodies of water, originating from the French word “porter,” meaning “to carry.”
In the context of Portage Pass, the name reflects its historical use as a passageway where traders and travelers carried their goods across land to continue their journey by water.
