About Twin Falls Gorge Territorial Park

Twin Falls Gorge Territorial Park is a Northwest Territories park south of the town of Hay River along the Waterfalls Route of the Mackenzie Highway. The park protects a dramatic stretch of the Hay River canyon that includes two of the largest waterfalls in the territory, Alexandra Falls and Louise Falls. Alexandra Falls drops roughly 32 metres into a sheer limestone gorge, while Louise Falls, about 3 kilometres downstream, plunges around 15 metres in a stair-step pattern. A connecting Gorge Trail follows the canyon rim between the two viewpoints, with lookouts, picnic areas, and interpretive panels about the area's geology and Dene history. The park is a popular stop for RV travellers driving between Alberta and the communities of the Dehcho and North Slave regions, offering a developed campground at Louise Falls and day-use facilities at Alexandra Falls.

Best time to visit Twin Falls Gorge Territorial Park

Late June through August is the prime window, with long daylight hours, warm temperatures, and full campground services at Louise Falls. Early June and early September are quieter shoulder periods, though nights turn cold quickly and biting insects peak in midsummer. Campground facilities typically close once snow and freezing temperatures arrive, so RV travellers should plan their visit before mid-September.

Things to do at Twin Falls Gorge Territorial Park

Alexandra Falls Viewpoint Easy
RV parking available
Alexandra Falls is the headline attraction, a 32 metre waterfall that thunders into a limestone canyon on the Hay River. A short, accessible path from the day-use parking area leads to fenced lookouts directly above the drop. Picnic tables and RV-friendly parking make it an easy stop off the Mackenzie Highway.
Louise Falls and the Wooden Staircase Easy
RV parking available
Louise Falls is a stair-step waterfall just downstream from Alexandra, with a viewing platform and a wooden staircase that descends partway into the gorge. The short walk from the campground or day-use lot offers close-up views of the falls and the canyon walls. Sturdy footwear is recommended on the stairs.
Gorge Trail Between the Falls Moderate
RV parking available
The Gorge Trail is a roughly 3 kilometre rim trail connecting Alexandra and Louise Falls. It passes several lookouts over the Hay River canyon and interpretive signs about boreal forest ecology and local Dene heritage. Most visitors hike one direction and shuttle back by RV.
Louise Falls Campground Stay
RV parking available
Louise Falls Campground is the park's overnight base, with powered and non-powered sites suited to RVs of varying sizes. Amenities include a sani-dump, kitchen shelters, firewood, and pit toilets, with the falls within walking distance of the loop. It is a convenient overnight between Alberta and Yellowknife.
Picnicking at Alexandra Falls Day-Use Easy
RV parking available
The Alexandra Falls day-use area offers covered picnic shelters, tables, and fire pits within earshot of the falls. It is a popular lunch stop for RV travellers on the Waterfalls Route. The large paved lot easily accommodates motorhomes and trailers.
Photography and Birdwatching Easy
RV parking available
The canyon rim is one of the best photography spots in the southern Northwest Territories, with dramatic light on the falls in early morning and evening. Boreal songbirds, swallows, and raptors are frequently seen along the gorge. Viewing platforms provide stable positions for tripods.
Waterfalls Route Road Trip Stop Easy
RV parking available
Twin Falls Gorge is the centrepiece of the NWT Waterfalls Route, which links several territorial parks along Highway 1 and 2. RVers often combine a visit with stops at Lady Evelyn Falls, Sambaa Deh Falls, and McNallie Creek. The paved highway and pull-through sites make multi-park touring straightforward.

How to get to Twin Falls Gorge Territorial Park

The park sits along Highway 1 (the Mackenzie Highway) in the Northwest Territories, about 70 kilometres south of the town of Hay River and roughly an hour north of the Alberta border crossing at 60th Parallel Territorial Park. From Edmonton, Alberta, the drive is approximately 1,200 kilometres and takes two to three days for an RV. The route is paved and generally RV friendly, but it is remote with long stretches between fuel stops, so RVers should top up in High Level, Alberta and Enterprise, NWT. The nearest airport for fly-and-rent trips is Hay River/Merlyn Carter Airport (YHY).
