The story of the Ponca underscores a stark but often-overlooked truth, that many of the trails we hike or bike in the US today were originally forged by Indigenous hunters and traders centuries earlier. When their lands were taken, federal and state governments turned some of these trails into roads and railways. (The Ponca’s Trail of Tears route, for instance, later became a now-defunct part of the Union Pacific railway line.)

But in recent years, tribes, states and organisations like the Rails-to-Trails Conservancy have been converting these ancient Indigenous tracks into modern bike and pedestrian routes, and breathing new life into them in the process. As Native groups are creating more slow tourism opportunities (such hiking, cycling and paddling) on their land or in areas strongly connected to Indigenous history, tribes are increasingly reclaiming their ancestral spaces.

“All these trails were trails that were here before, and most trails throughout American Indian country that people are using now for slow tourism, were our trails, wherever you go,” said Judi gaiashkibos, the executive director for the Nebraska Commission on Indian Affairs and a Ponca Tribe member. She explained that the deed to the Chief Standing Bear Trail now belongs to the Ponca, and educational kiosks and signs along the route help tell their history. Gaiashkibos hopes to attract travellers “to come hear new stories, to slow their lives down and to be connected to the land”.

Indigenous tourism is growing across North America. In Canada, it accounts for nearly $2bn of the nation’s GDP, while in the US, Native tourism is a $14bn industry. Tribes are increasingly making use of their best assets to propel this trend: their people and their land.

In Washington, the nearly completed 135-mile Olympic Discovery Trail (ODT) is already becoming one of the state’s biggest non-motorised tourism attractions. Running from Puget Sound to the Pacific Ocean, it offers joggers, cyclists and hikers stunning views of the Olympic Peninsula‘s snow-capped peaks, temperate rainforests and glacial lakes. Built on a now-defunct railroad, this was originally a foot trail that connected various tribal villages. One of those tribes is the Jamestown S’Klallam Tribe. 

Today, the trail travels through the Jamestown S’Klallam Tribal Government North Campus and their 7 Cedars Casino, with educational signage along the way, as well as the Native Art Gallery that sells the work of Native American artists, books and gifts. It also passes by the Jamestown S’Klallam Tribal Library, which houses books written by Native American authors and serves as a cultural resource for tribal members and guests.

“Inside the library, we’re creating some exhibit space that is allowing the tribe an opportunity to tell the tribe’s story from the tribe’s perspective, with a focus on tribal priorities not somebody else’s narrative.” said Luke Strong-Cvetich, Jamestown S’Klallam’s tribal planning director.

The tribe is also successfully cleaning up contaminated land and restoring salmon habitat along the trail. “The newly expanded Dungeness River Nature Center [is the] “crown-jewel,” said Strong-Cvetich. “It is [an] educational facility-visitor centre on the Dungeness watershed,” which is the tribe’s river and a main salmon habitat. Guests can learn about conservation and the importance of this watershed for the tribe, which has relied on a strong salmon populations for millennia.

In Idaho, the Coeur d’Alene Tribe is also incorporating slow tourism to reclaim their land and story.

The tribe’s ancestral territory was once five million acres that stretched from Spokane, Washington, across the Idaho panhandle into Montana. Yet, the arrival of settlers in 1883 and the eventual Allotment Act in 1909 left them with only 345,000 acres, and their many hunting and trade routes became the corridors for interstates like I-90, or the Washington & Idaho Railroad.

When the Washington & Idaho Railroad ceased operation, a roughly 72-mile paved bike trail – The Trail of the Coeur d’Alenes – was created. The trail crosses the panhandle and the tribe oversees 15 miles of the trail. Their Coeur d’Alene Casino Resort Hotel now uses this trail as part of their cultural tourism programme, offering everything from guided hikes along ancestral paths to tribal-led canoe and kayak tours on Lake Chatcolet to Indigenous-led guided cycling excursions across the Trail of the Coeur d’Alenes (bikes are provided for guests).

“We don’t have a cultural centre,” said Wasana McGowan, who manages cultural tourism at the casino. “So what do we do? We use the lands. We use the reservation that we’re on.” 

In the American Southwest, many travellers might be familiar with Grand Canyon National Park, but a four-hour drive west is Grand Canyon West (GCW), located on the Hualapai Nation reservation. Visitors will find the same jaw-droppingly deep canyon with its soft orange and pink hues, but also the striking, horseshoe-shaped Skywalk: a glass bridge owned and operated by the Hualapai that stretches 70ft out over the canyon edge.

Visitors to GCW can explore nearby hiking trails, zipline 500ft above the floor of a side canyon and meet cultural ambassadors who explain Hualapai culture and history. Their new app also allows guests to learn on their own through videos, interviews, photos and maps.

“The tourists that visit here at Grand Canyon West, they know very little about Hualapai people and the land-base that they’re standing on,” said Loretta Jackson-Kelly, supervisor for the Grand Canyon West ambassador department. “As ambassadors, we’re the ones that relay that history and the Hualapai culture.”

But the real centrepiece of the Hualapai’s tourism offerings is another type of trail: the Colorado River.

For centuries, the Colorado River network connected tribes and trade. It is central to Hualapai identity and their creation story. Its oxbow curves once traced the boundary of the nation’s seven-million-acre ancestral land. But when gold was discovered in 1863, that river and its access was divided up by the US government for mining, leaving the Hualapai exiled until they secured a one-million-acre reservation in 1883. 

Today, the Hualapai River Runners take guests rafting down the Colorado River and explore sacred places by hiking with tribal river guides. “The Hualapai people are immensely proud to show off their backyard… one [of the] wonders of the world: the Grand Canyon and Colorado River,” said Jackson-Kelly.

Through tourism, the river and the Hualapai’s history, like that of so many other First Nations tribes around the US, is finally being retold through Indigenous voices.
