South Chilcotin Mountains

South Chilcotin Mountains Provincial Park is a wilderness park in the Chilcotin Ranges of southwestern British Columbia, about 150 km north of Whistler and 95 km west of Lillooet, reached from Lillooet along Carpenter Lake on Highway 40. ^[1] The park protects 56,796 hectares (about 568 square kilometres). ^{[2] [3]} It was first proposed for protection in 1937, was designated a protected area in April 2001, and received its present boundaries and Class A park status in June 2010. ^[1] BC Parks describes a visually spectacular area of mid-elevation grasslands, subalpine and alpine meadows, lakes, and mountain peaks, which includes the complete watersheds of Lizard and Leckie creeks and significant parts of other large intact watersheds and headwaters. ^[1] Some of its higher peaks, such as Mount Warner at 2,834 m, are relatively rugged, and the park's landscape straddles the boundary between the southeast Coast Mountains and the Chilcotin Plateau. ^[1] Over 200 km of interconnected trails cross valleys, alpine meadows, and ridges, and the park lies within the territory of the Tsilhqot'in, St'at'imc, and Secwepemc Nations. ^[1] The park protects habitat for mountain goats, grizzly bears, and other wildlife that need large, undisturbed territories, and its minimal development means visitors experience true wilderness conditions.

Many species of large mammals live in the park, including mountain goats, mule deer, grizzly bears, black bears, bighorn sheep, and moose; cougars and wolves may also be present. ^[1] BC Parks notes a good chance of encountering grizzly bears when visiting, and wolverines are an occasional, lucky sighting. ^[1] Smaller mammals include marmots, pikas, and Columbia ground squirrels, and a wide variety of small fur-bearers, including lynx, beaver, mink, muskrat, marten, and wolverine, also live here. ^[1] Birdlife includes larks, pipits, ptarmigans, grouse, jays, woodpeckers, nutcrackers, chickadees, nuthatches, siskins, kinglets, dippers, thrushes, robins, and warblers, as well as eagles, falcons, hawks, and owls. ^[1] Creeks in the park are home to bull trout, and the lakes contain rainbow trout, mountain whitefish, and kokanee. ^[1]

South Chilcotin Mountains Park includes lush grasslands and meadows in its alpine and subalpine areas, and large areas of aspen and conifer forest in the Tyaughton, Gun, and Relay creek valleys. Engelmann spruce, subalpine fir, Douglas-fir, lodgepole pine, and whitebark pine forests are all present. ^[1] BC Parks describes the park as a visually spectacular area of mid-elevation grasslands, subalpine and alpine meadows, lakes, and mountain peaks. ^[1] Hiking off-trail damages its fragile grassland and alpine ecosystems and causes erosion, so visitors are asked to stay on designated trails. ^[1]

South Chilcotin Mountains Park is in an area of complex geology that straddles the boundary between the southeast Coast Mountains and the Chilcotin Plateau. The gently sloping valleys and dome-shaped mountains that typify the Chilcotin Ranges form the core topographic features of the park. ^[1] Fossils demonstrate the marine origin of many of the park's sedimentary rocks. Well-preserved late Triassic marine fossils (ammonites and bivalves) are found in the Tyaughton Creek area, and lower and middle Jurassic rocks nearby are also locally rich in fossils, mainly ammonites. ^[1] The Relay Mountain Group is in part extremely rich in upper Jurassic and lower Cretaceous fossils, found around upper Relay Creek, Elbow Mountain, and the low bluffs northwest of Spruce Lake. It is illegal to remove fossils or any other natural or cultural artifacts from a BC park. ^[1] Extensive alpine areas supply abundant water to the park's creeks, and lakes and tarns occur at the headwaters of Slim, Leckie, and Upper Gun creeks. Spruce Lake sits in the high pass between the Gun and Tyaughton valleys, and wetlands and braided channels are typical of the upper reaches of the southern creeks and of upper Tyaughton Creek. ^[1]

South Chilcotin Mountains Park has less precipitation than the surrounding areas, and its summer temperatures are moderately cool. Frost is expected in most months at lower elevations and year-round in the alpine area. ^[1] The lowest elevations of the park, in the lower Gun and Tyaughton creek valleys, are the warmest and driest parts of the park, and they are often windy throughout the year. ^[1] The park lies on the leeward side of the major coastal ranges, which accounts for its lower precipitation. ^[2] Even in summer, storms with snow are common at higher elevations and conditions can change quickly, so visitors should be prepared for winter conditions at any time. ^[1] Valley-bottom summer temperatures typically reach 15-25 degrees Celsius, while alpine areas rarely exceed 15 degrees Celsius even at the peak of summer. The short alpine growing season, generally June through September, constrains plant growth and wildlife activity.

The area known as South Chilcotin Mountains Park has been used by Indigenous Peoples for thousands of years, and they continue to maintain cultural connections to it. It falls within the territory of three Nations: the Tsilhqot'in, St'at'imc, and Secwepemc. ^[1] In more recent history, the area has also been used for mining, ranching, and recreation. ^[1] Several cabins in the park remain private property and are not for public use. ^[1] Today the park is used for a range of recreational activities, including hiking, horseback riding, cycling, fishing, and winter recreation. ^[1]

The area now protected as South Chilcotin Mountains Provincial Park was first proposed for protection in 1937. It was designated a protected area in April 2001, and in June 2010 its present boundaries were established and it was designated a Class A park. ^[1] The present park was established by the Protected Areas of British Columbia Amendment Act, 2010 (Bill 15), with an area of approximately 56,796 hectares. ^[2] Through various wilderness studies and special management processes, much of the area's wilderness character has been maintained. ^[1] BC Parks manages the park under the South Chilcotin Mountains Park and Big Creek Park Management Plan and an Aviation Management Plan covering 2022 to 2026. ^[3] Float planes use Spruce and Warner lakes as landing areas. ^[1] Commercial recreation services, including guided hiking, fishing, horseback and cycling trips, operate under park-use permits issued by BC Parks. ^[1] The park falls within the territory of three Nations, the Tsilhqot'in, St'at'imc, and Secwepemc. ^[1]

More than 200 km of interconnected trails run through valleys, alpine meadows, and ridges, offering loop trips of varying difficulty for hiking, horseback riding, and cycling. ^[1] BC Parks says the park provides some of the best mountain biking experiences in British Columbia, but cycling is allowed only on the designated trails shown on its official map. ^[1] The Gun Creek-Spruce Lake Trail starts at Jewel Creek, and Spruce Lake, which sits in the high pass between the Gun and Tyaughton valleys, is the most common fishing destination, with rainbow trout also found in Trigger, Hummingbird, and Warner lakes. ^[1] Visitors can swim in Spruce, Trigger, Hummingbird, and Warner lakes, though the water is cold even in mid-summer, and Spruce Lake North Campground has a dock. ^[1] Cowboy Camp on the Grasslands Trail is a good location for horse groups. ^[1] In winter the park offers winter camping, cross-country skiing, ski-mountaineering, heliskiing, and snowshoeing. ^[1] The 2023 Downton Lake wildfire left hazards such as danger trees, damaged trail surfaces, and unstable soil and terrain on the lower portions of the Gun Creek Trail and at the Jewel Creek parking lot. ^[2] In September 2026 BC Parks partially closed the park, including the Tyaughton Creek, Castle Pass, Relay Creek, and Little Paradise Creek trails, because of their proximity to a fire boundary, so visitors should check current advisories before travelling. ^[2]

South Chilcotin Mountains Park is largely a wilderness area with very few maintained facilities, and there are no BC Parks staff in the park. ^[1] Access is from Lillooet along Carpenter Lake on Highway 40. In summer, access from Pemberton is available via the Hurley Forest Service Road to Gold Bridge, which climbs steeply to 1,850 m and can be very rough. ^[1] To reach the Jewel Bridge trailhead, take the Slim Creek Forest Service Road about 7 km east of Gold Bridge on Highway 40 and head generally north for about 12 km to the start of the Gun Creek-Spruce Lake Trail at Jewel Creek. The park can also be reached from the southeast and east on logging and mining roads, many of which need a four-wheel-drive vehicle. ^[1] The nearest communities with services are Lillooet and Gold Bridge. ^[1] ATVs and other off-road vehicles are not allowed in the park, and pets should not be brought because of the danger of conflict with wildlife, especially bears. ^[1] Drinking water is not available, and water from lakes and streams must be boiled, filtered, or otherwise treated; the park has limited connectivity, so a printed map is recommended. ^[1] Six designated backcountry camping areas are user-maintained with very limited facilities, most with picnic tables, food caches, and pit toilets, and wilderness camping is allowed throughout the park. ^[2] Hummingbird and Spruce Lake South campgrounds have been closed because of hazardous trees; Trigger Lake, Spruce Lake North, and the Gun Creek Grassland-Cowboy Camp are the nearest open alternatives. ^[3] Float planes use Spruce and Warner lakes as landing areas and may land at any time. ^[1] Backcountry travelers must carry topographic maps and navigation equipment and should register their travel plans with friends or family.

South Chilcotin Mountains Park is largely a wilderness area, and BC Parks asks visitors to stick to designated trails, since hiking off-trail damages fragile grassland and alpine ecosystems and causes erosion. ^[1] The park encompasses the complete watersheds of Lizard and Leckie creeks and significant parts of other large intact watersheds and headwaters. ^[1] Dogs and other pets are not allowed because of the significant danger of conflict between domestic animals and wildlife, especially bears, and visitors are told to make noise on trails and to keep food waste and other scents from attracting wildlife. ^[1] Harvesting mushrooms, plants, and other natural resources is not allowed unless specifically authorized, although Indigenous Peoples may harvest in accordance with Aboriginal and Treaty rights. ^[1] Cycling off designated trails is an offence that can result in a fine and eviction from the park. ^[1]
