Running

Embark on the Harding Icefield Trail for a challenging jogging experience that takes you through diverse Alaskan landscapes. This difficult route spans 8.6 miles (13.8 km) and climbs 3035 feet (925 metres), typically requiring about 2 hours and 44 minutes to complete. As you ascend, you will move from lush forest floors, past vibrant wildflower meadows, and into rugged alpine terrain, eventually reaching a commanding view of the vast icefield.

Before you head out, be aware that conditions can change rapidly; cell service is unreliable, and higher elevations may remain snow-covered well into July. Always carry appropriate layers, rain gear, and plenty of water to stay prepared for sudden weather shifts. This trail presents a significant physical challenge, so plan your visit carefully and ensure you are adequately prepared for the strenuous climb.

The Harding Icefield Trail offers a unique opportunity to witness one of North America's largest icefields, where mountain peaks, known as nunataks, pierce through the endless expanse of ice and snow. Keep an eye out for local wildlife, including bears and mountain goats, which are often spotted along the route. This journey provides a profound connection to the raw, untamed beauty of Kenai Fjords National Park.

View of the Harding Icefield

Highlight • Viewpoint

This is the terminus of the Harding Icefield Trail. The massive sheet of ice that spreads out to the horizon from here is the birthplace of more than 35 glaciers — the headwaters of those slow-flowing rivers of ice, if you will.

You earned these views, so look your fill — but don't venture onto the ice unless you have the proper equipment and training for glacier travel, and are ready to deal with rapidly changing weather. In fact, the weather up here can be so changeable that there's an emergency shelter.

Frequently Asked Questions

Where does the Harding Icefield Trail start and where can I park?

The Harding Icefield Trail begins at the Exit Glacier Nature Center, located within Kenai Fjords National Park near Seward, Alaska. Parking is available at the nature center.

Do I need a permit or pay an entrance fee to access the trail?

No, there are no entrance fees or permits required to hike the Harding Icefield Trail or to enter the Exit Glacier area of Kenai Fjords National Park. However, standard National Park Service regulations apply.

What are the regulations for visiting Kenai Fjords National Park?

As part of Kenai Fjords National Park, visitors should adhere to Leave No Trace principles. This includes packing out all trash, staying on marked trails, and respecting wildlife. Specific regulations regarding pets, camping, and other activities can be found on the official NPS website.

How challenging is the Harding Icefield Trail for jogging?

The Harding Icefield Trail is considered difficult and strenuous, making it suitable for jogging only by very fit and experienced trail runners. It involves significant and continuous elevation gain, with hikers gaining approximately 1,000 feet per mile for much of the ascent. The varied terrain, including rocky sections and potential snowfields, adds to the technical difficulty.

What is the terrain like on the trail?

The terrain is diverse and progressively more demanding. It starts with a relatively flat, paved path through forests, then transitions into bushy areas, tundra meadows, and eventually rocky, alpine landscapes above the tree line. Expect significant rock steps, switchbacks, and potentially muddy sections. Higher elevations can retain snow, especially through July.

What kind of views and landmarks can I expect along the trail?

The trail offers evolving and spectacular views. You'll see the valley floor, Exit Glacier, and surrounding mountains. Higher up, you'll pass through wildflower meadows and gain expansive views of Exit Glacier below. The "Top of the Cliffs" provides stunning vistas of blue glacial ice. The ultimate reward is a sweeping view of the Harding Icefield itself, a vast expanse of ice and snow.

What wildlife might I see on the Harding Icefield Trail?

The trail is home to various wildlife. Keep an eye out for black bears, brown bears, mountain goats, and marmots, which can often be spotted along the route. Remember to maintain a safe distance and never feed wild animals.

What is the best time of year to experience the trail, and what are the seasonal considerations?

The best time to visit is typically from late June through early September when snow has largely melted from the upper sections. However, even in July, higher elevations can still have snow, potentially requiring mountaineering skills and equipment. Weather conditions can change rapidly, so always be prepared for rain and colder temperatures.

Is the Harding Icefield Trail suitable for dogs or families with children?

Due to its strenuous nature, significant elevation gain, and varied terrain, the Harding Icefield Trail is generally not recommended for young children or those seeking a casual family outing. Dogs are permitted on the trail but must be kept on a leash at all times, and owners are responsible for packing out all waste.

Does the Harding Icefield Trail connect with other paths?

Yes, the route primarily follows the Harding Icefield Trail, but it also passes through sections of the Glacier View Loop Trail and the Overlook Trail near the beginning.

What should I pack for a trip on the Harding Icefield Trail?

Given the trail's difficulty and unpredictable Alaskan weather, essential items include plenty of water, high-energy snacks, layers of clothing (including rain gear), sturdy hiking boots, sun protection, and bear spray. Trekking poles are highly recommended for the steep and rocky sections. Cell service is unreliable, so a map and compass or GPS device are also advisable.
