The YukonCoal River Springs Territorial Park
A rare, actively growing set of cold-water tufa terraces in one of the most remote corners of the Yukon.
What makes it unusual
Coal River Springs protects a genuinely rare geological feature: an active tufa system where mineral-rich groundwater emerges from limestone and deposits pale, terraced pools as it flows downhill. These are cold springs, not hot springs, despite the word "springs" in the name, and the terrace walls grow at a rate of roughly 2 to 3 centimetres a year as dissolved limestone builds up, eventually forming domes with new pools developing on top of older ones. Established in 1990 as Yukon's second territorial park and its first ecological reserve designation, the park was created through the combined efforts of the Government of Yukon, the Liard First Nation, and the Nature Conservancy of Canada. The whole protected area covers only about 16 square kilometres, small, but chosen specifically to safeguard something genuinely singular.
Getting there is the real story
This is one of the hardest-to-reach places in the territory, and it's worth understanding why before you plan around it. There is no road and no trail. Bushwhacking in from the nearest rough mining or logging road is explicitly discouraged by Yukon Parks itself: the route crosses roughly 2 km of large, burned deadfall, is extremely difficult even for experienced backcountry travellers, and the Coal River cannot be crossed on foot at any time of year. This is not a shortcut option.
Real access comes down to three routes. Floatplane charter from Watson Lake is the most common, landing on a nearby lake, and requires a park permit to land an aircraft within the park boundary. Helicopter charter from Watson Lake, roughly 80 km away, is typically about a one-hour return flight, also permit-required. The third option is by canoe, for experienced paddlers only: reaching the springs via the Coal River commits you to a roughly week-long trip with grade III-IV rapids both above and below the springs, putting in near Watson Lake and taking out where the Coal River crosses the Alaska Highway in British Columbia. Whichever way you go, a permit from Yukon Parks in Watson Lake is mandatory, and you're expected to check in for a safety briefing before you fly or paddle in.
What's there
A small camping area and outhouse sit about 200 metres east of the main limestone formations, the only visitor facility in the park. Viewing platforms and boardwalks keep visitors off the fragile tufa itself; a single footprint can damage decades of mineral growth, so staying on the designated walkways isn't optional. Hiking opportunities beyond the immediate springs area are limited, this is a destination built around the springs themselves, not a wider trail network.
Wildlife
The surrounding boreal wilderness, spruce forest, muskeg, and spring-fed creeks, supports wolves, black and grizzly bears, moose, beaver, and a range of boreal birds. Early mornings and evenings near the springs and river tend to offer the best wildlife viewing.
Questions, answered
How do I get to Coal River Springs?
By floatplane or helicopter charter from Watson Lake, or by a committing week-long canoe trip down the Coal River with grade III-IV rapids. Bushwhacking in on foot is explicitly discouraged by Yukon Parks and involves crossing a river that cannot be forded at any time of year.
Do I need a permit?
Yes, for landing an aircraft in the park and generally to visit at all. Contact Yukon Parks in Watson Lake well ahead of your trip for the permit and required safety briefing.
Are these hot springs?
No. Despite the name, Coal River Springs are cold-water springs, not thermal ones.
How long does a visit take?
Most visits run several days once you account for travel time in and out, plus weather buffers, since floatplane and helicopter access both depend on conditions.
When can I visit?
The park is technically accessible year-round, but realistic access depends on when floatplanes can land on open water and when the Coal River is runnable, generally summer months.
