Access one of the most remote and beautiful valleys in the Canadian Rockies, where the Ramparts — a cathedral wall of 1,000-metre cliffs — rise dramatically above Amethyst Lakes. Horse-guided trips also available. Backcountry camping with permit.
The Tonquin Valley Trail provides access to one of the most remote and visually dramatic backcountry destinations in Jasper National Park, Alberta. The route travels approximately 36 km return to Amethyst Lakes at the base of the Ramparts — a near-vertical wall of quartzite towers rising over 1,000 metres above the valley floor and stretching more than 10 km along the Continental Divide. The combination of mirror-still lakes and towering peaks is considered among the finest alpine scenery in the Canadian Rockies.
Two primary hiking routes serve the valley: the Astoria River Trail from Portal Creek trailhead (via Highway 93A south of Jasper townsite) and the Maccarib Pass route from Marmot Basin Road. The Maccarib Pass approach (approximately 19 km one-way) is the more scenic and more commonly used option, crossing a high wildflower-covered pass at 2,210 metres before descending to the lakes. The Astoria River route is shorter and lower but heavily shared with horse parties. Both trailheads are within 30-45 minutes' drive of Jasper townsite.
Backcountry camping permits are required and must be reserved through Parks Canada's reservation system, which opens in January. Amethyst Campground and the adjacent Wates-Gibson Hut (operated by the Alpine Club of Canada) provide the primary overnight options. The ACC hut offers dormitory-style bunks, cooking facilities, and a wood stove — a significantly more comfortable alternative to tenting in inclement weather — but advance booking is required directly with the Alpine Club of Canada.
The terrain is generally moderate — long valley walks with one significant pass crossing (Maccarib) and no technical sections. The surface ranges from rocky backcountry trail to boggy alpine meadow in the valley floor. Wildlife in the Tonquin Valley is exceptional: woodland caribou from the vulnerable Tonquin herd are regularly encountered near the lakes, alongside grizzly bears, wolves, wolverines, and dense populations of pika and hoary marmot. Mosquitoes are intense in July; insect repellent is essential throughout the summer season.

Tips for visiting
- Secure a backcountry camping permit through Parks Canada in January — the Tonquin Valley is popular and mid-summer dates book quickly.
- Insect repellent is essential in July when mosquito populations in the valley floor are extreme; carry more than expected.
- The Maccarib Pass route is the more scenic approach; combining it with the Astoria River trail on the return creates a loop if transport between trailheads can be arranged.
- The Alpine Club of Canada's Wates-Gibson Hut offers a more comfortable overnight option than camping; reserve directly with the ACC well in advance.
- Bear spray is mandatory — grizzly bears and wolves are active throughout the valley.
- Horse parties share the Astoria River trail and have right-of-way; step to the downhill side and stand quietly when letting horses pass.
When to visit
Mid-July to mid-September offers the most reliable conditions. Early July can have snow on Maccarib Pass; September brings cooler temperatures and reduced insect activity but shorter daylight hours for multi-day itineraries.
Accessibility
The Tonquin Valley Trail is not accessible to wheelchair users or those with mobility limitations. The route involves multi-day backcountry travel over rocky and boggy terrain, including a significant pass crossing at 2,210 metres, far from any vehicle road.
Frequently asked questions
Is the Tonquin Valley accessible as a day hike?
A day hike is possible via the shorter Astoria River route but the 36+ km round trip is beyond most day hikers' range. An overnight stay dramatically improves the experience and allows time to explore the lake shore and appreciate the Ramparts at changing light.
Can visitors expect to see caribou?
Woodland caribou from the Tonquin herd are regularly spotted in the valley and near Amethyst Lakes, particularly in early morning and evening hours. They are a vulnerable population; hikers should maintain distance and avoid approaching or following the animals.
What is the Wates-Gibson Hut?
The Wates-Gibson Hut is a backcountry hut operated by the Alpine Club of Canada, located near the shore of Amethyst Lakes. It provides dormitory bunks, a cook stove, and basic kitchen equipment. Advance reservation through the ACC is required.
Are horse parties a significant factor on the trail?
Yes, horse-guided trips are a traditional means of accessing the Tonquin Valley and share portions of the trail, particularly the Astoria River route. Horse parties have right-of-way; hikers should step to the downhill side and stand quietly to allow horses to pass calmly.
Is the trail well enough marked to navigate without a map?
The trail is maintained and marked with orange diamond blazes, but a topographic map and compass or GPS device are recommended given the remote location and the potential for poor visibility on the exposed Maccarib Pass section during adverse weather.
