McArthur Hot Springs

## Overview McArthur Hot Springs is a remote natural hot spring located in the Yukon Territory of Canada, situated at approximately 63.114°N, 136.066°W. Nestled deep within the rugged subarctic wilderness of central Yukon, this geothermal feature lies in a region shaped by ancient volcanic and tectonic activity along the Tintina Trench — a major geological fault zone that runs through the territory and is responsible for many of Yukon's thermal springs. Yukon's hot springs have long been valued by Indigenous peoples, and many have served as gathering and healing places for centuries. McArthur Hot Springs sits in the traditional territories of First Nations communities who have called this landscape home since time immemorial. The spring's remote location means it sees very few visitors, offering a rare and pristine wilderness soaking experience for those willing to make the journey. Due to its extreme remoteness, very little published data is available regarding the water temperature, mineral content, or flow rate of McArthur Hot Springs. Yukon hot springs in this region are typically fed by deep geothermal circulation along fault lines and often contain elevated levels of dissolved minerals such as calcium, sulfate, and silica. Water temperatures at similar Yukon hot springs range widely, from warm seeps to pools exceeding 40°C (104°F). ## Directions McArthur Hot Springs is located in a very remote area of central Yukon, well off any maintained road system. Access likely requires one or more of the following: 1. **By Air:** Charter a bush plane or helicopter from Whitehorse, Dawson City, or Mayo to reach the general area. This is the most practical option for many remote Yukon hot springs. 2. **By Land (Seasonal):** Depending on the time of year, access may be possible via winter trails, ATV routes, or extended backcountry hiking. Local outfitters or First Nations tourism operators in the region may be able to provide guidance on current access conditions. 3. **GPS Coordinates:** 63.1140, -136.0659. A reliable GPS device or satellite communicator is essential, as there is no cell service in this area. Visitors should consult with local authorities, outfitters, or the Yukon government's hot springs resources before attempting to reach this site. Conditions can change dramatically with the seasons. ## What to Expect McArthur Hot Springs is a true backcountry destination. Visitors should be prepared for a wilderness experience with no developed facilities, signage, or maintained trails. The surrounding landscape is characterized by boreal forest, river valleys, and mountainous terrain typical of central Yukon. - **Remoteness:** This is one of the more isolated hot springs in the Yukon. Self-sufficiency is critical — bring all supplies, emergency gear, and a satellite communication device. - **Wildlife:** The area is home to grizzly bears, moose, wolves, and other large wildlife. Bear-aware practices are essential. - **Seasonal Access:** Summer (June–August) offers the longest daylight and most accessible conditions, though mosquitoes and black flies can be intense. Winter travel is possible but demands serious cold-weather expertise. - **Water:** As with all natural hot springs, water conditions can vary. The water has historically been used for soaking by those who have visited, but no official water quality testing data is publicly available for this site. - **Leave No Trace:** Given the pristine and fragile nature of this environment, visitors are strongly encouraged to practice Leave No Trace principles to preserve the spring for future visitors.
