Shoreline of Portage Lake
Highlight • Lake
If you see a small cruise ship on the water that is the M/V Ptarmigan, which cruises from the visitor center on the far side of the lake to within good views of the face of Portage Glacier; more information here: graylinealaska.com/portage-glacier-cruises
Finally, some hikers do choose to continue hiking left (south) from here, in hopes of getting closer to the face of the glacier itself. Be warned, there is a not-insignificant stream crossing in the way, and it's very dangerous to walk on, underneath, or in front of the glacier itself, as chunks of ice can and do break off of it at random intervals.

Burns Creek
Highlight • River
If you do choose to cross and continue toward the face of the glacier, please remember that it's very dangerous to walk on the glacier ice or in close proximity to it; falling chunks of ice could crush you.

Frequently Asked Questions
How long does it typically take to hike the Portage Pass Trail?
The full out-and-back hike, covering approximately 8.9 kilometers, generally takes around 3 to 4 hours to complete. This includes time for enjoying the views at Portage Pass and the Shoreline of Portage Lake.
What is the terrain like on this trail?
The trail begins with a significant, steep uphill climb for the first mile, gaining about 750-800 feet. The surface is predominantly ground but includes rocky sections, loose stones, mud, and sometimes running water or snow patches. After the pass, it descends more gradually towards Divide Lake and Portage Lake. Proper hiking boots are essential due to the varied and uneven ground.
Where is the trailhead located and what are the parking options?
The Portage Pass Trailhead is located near Whittier, Alaska. To reach Whittier, you'll need to drive through the Anton Anderson Memorial Tunnel. There is parking available at the trailhead. It's advisable to arrive early, especially on weekends, as parking can fill up.
Is the Portage Pass Trail suitable for beginners or families with children?
While the initial steep ascent makes it a 'moderate' to 'more difficult' trail, many consider it family-friendly with effort. The option to turn around at Portage Pass offers a shorter outing for those seeking less challenge. Children who are accustomed to hiking and can handle a significant climb will enjoy the experience.
What can I see along the route, and are there any notable viewpoints?
The trail offers spectacular views. As you ascend, you'll see Whittier and Passage Canal. Upon reaching Portage Pass, you'll be rewarded with awe-inspiring panoramic views of Portage Glacier and Portage Lake. You'll also pass by Burns Creek and the Shoreline of Portage Lake.
What is the best time of year to hike this trail?
The best time to hike is typically from late spring through early fall (June to September) when the trail is mostly free of snow and wildflowers are in bloom. Berry patches are also abundant in season. Winter hiking is possible but requires appropriate gear and experience due to snow and ice conditions.
Are dogs allowed on the Portage Pass Trail?
Yes, dogs are generally allowed on the trail. However, as it is located within the Chugach National Forest, it's important to keep your dog on a leash and practice Leave No Trace principles, including packing out all waste.
Do I need a permit or is there an entrance fee for the trail or Chugach National Forest?
There is no specific permit required to hike the Portage Pass Trail itself. However, there is a fee to use the Anton Anderson Memorial Tunnel to access Whittier, which is necessary to reach the trailhead. Check the tunnel's operating schedule and fees before your visit.
What kind of wildlife might I encounter on the trail?
The trail passes through open tundra where you might spot wildlife such as mountain goats. It's also an important migratory route for birds, making it a good spot for birdwatching. Always maintain a safe distance from any wildlife you encounter.
What should I bring for a hike on the Portage Pass Trail?
Given the varied terrain and potential for changing weather, essential items include sturdy hiking boots, layers of clothing, rain gear, plenty of water, snacks, and bear spray. Binoculars are also recommended for wildlife viewing and enjoying the distant glacial scenery.
Is there a local secret or strategy for hiking this trail?
To fully appreciate the stunning views of Portage Glacier and Portage Lake, consider hiking the entire out-and-back route. While the initial climb is steep, the reward at the pass and the descent to the lake's edge are truly spectacular and offer the best close-up views of the glacier, which is no longer easily accessible by other means.
