Sx̱ótsaqel/Chilliwack Lake Park

Sx̱ótsaqel/Chilliwack Lake Provincial Park is a wilderness park in southwestern British Columbia, 150 km east of Vancouver in the upper Chilliwack River Valley. BC Parks describes it as characterized by a valley-bottom lake, old-growth forested slopes, and spectacular subalpine and alpine ridges. ^[1] The park protects 9,273 hectares (about 93 square kilometres). ^[2] The dual name reflects the Halkomelem name Sx̱ótsaqel, meaning "sacred lake", and the English name of the lake; the area is the ancestral homeland of the Ts'elxwéyeqw Tribe, and the park was renamed in 2021. ^[3] The lake suits motorboating, canoeing, kayaking, swimming, and fishing, and the park offers 40 km of trails for hiking, bird and wildlife viewing, and nature appreciation. ^[1]

The park's range of habitats supports more than 40 mammal species, more than 20 reptiles and amphibians, and more than 130 bird species. ^[1] Rare and endangered species that need careful management include the Pacific giant salamander, Trowbridge's shrew, and the spotted owl, while grizzly bear, mountain goat, and Roosevelt elk are rare visitors. ^[1] The protected area holds more than 11 fish species: Chilliwack Lake supports suckers, mountain whitefish, steelhead, rainbow trout, Dolly Varden, kokanee, and five salmon species, and bull trout have been reported in the lake. ^[1] Sockeye and coho spawn at the mouths of the lake's tributaries, pink salmon spawn at the lake outlet, chum spawn in Paleface Creek, and kokanee spawn in Paleface, Depot, and Hanging Lake creeks and the upper Chilliwack River. ^[1] BC Parks reminds visitors to be aware of bears and other wildlife at all times and never to feed or approach them. ^[2]

BC Parks describes the park's slopes as old-growth forest rising to subalpine and alpine ridges. ^[1] The park takes in three biogeoclimatic zones, Coastal Western Hemlock, Mountain Hemlock, and Alpine Tundra, and two subzones of the Coastal Western Hemlock zone; the Southern Variant of its dry submaritime subzone is the southernmost example in the province. ^[2] The adjoining Chilliwack River Ecological Reserve protects a floodplain of old-growth forest, where spruce trees are hybrids of coastal Sitka spruce and interior Engelmann spruce. The largest grand fir ever measured in British Columbia grows in the reserve, and western redcedar and Douglas-fir there reach near-record sizes. ^[2] Lodgepole pine forests on the flats north of the lake are shaped by fire, and BC Parks has identified rare plants on the Mount Lindeman ridge for study. ^[2]

Chilliwack Lake sits in a U-shaped glacial valley. ^[1] The park is a classic British Columbia lake and mountain landscape: a large valley-bottom lake enclosed by steep valley walls and subalpine ridges, in the southern part of the Eastern Pacific Ranges Ecosection. ^[2] Chilliwack Lake, the upper Chilliwack River, several mountain lakes, tributary streams, and cascades are the dominant water features. ^[2]

The park experiences a transitional climate between coastal and interior patterns, with wet winters and relatively dry summers moderated by elevation and topography. Valley-bottom areas receive 1,500-2,000 millimeters of precipitation annually, increasing substantially with elevation as moisture-laden air masses rise and cool. Winter brings heavy snow to higher elevations with accumulations exceeding 5-10 meters in alpine areas, creating avalanche hazards and limiting access. Summer temperatures at the lake typically range from 15-25°C, pleasant for camping and water activities, while higher elevations remain much cooler. Weather can change rapidly, with storms bringing rain, wind, and reduced visibility even during summer months. Spring snowmelt peaks in May and June, swelling streams and rivers with cold glacial meltwater. Autumn features spectacular foliage colors and increasingly unsettled weather as winter storm patterns establish. Severe afternoon winds occur frequently on the lake. ^[1]

The Chilliwack Lake area is the ancestral homeland of the Ts'elxwéyeqw Tribe. ^[1] An ancient Indigenous trail joined nine Indigenous villages between Vedder Crossing and Chilliwack Lake, and the Hudson's Bay Company improved it and cut the first recorded trail up the Chilliwack River in 1855. ^[2] The Northwest Boundary Survey of 1857 to 1862 used the Chilliwack River to reach the 49th parallel, and British and American survey parties set up base camps on Chilliwack Lake. ^[3] Logging in the valley began early in the 20th century and by the 1920s had grown into a considerable railroad logging operation. In 1938 a massive fire started by a rail accident led to the line being abandoned and a switch to truck logging. ^[2] In 1942 an army base was established in Chilliwack, and Sappers Park at the south end of the lake was built by a visiting British company of military engineers. ^[2]

The park was established as a Class A park by Order in Council 2544 on 24 July 1973 with 384 acres (about 155 hectares), and was expanded in 1974 and again in 1997, when the Park Amendment Act set its extent at 9,258 hectares. ^[1] BC Parks currently gives the park's area as 9,273 hectares. ^[2] It was renamed Sx̱ótsaqel/Chilliwack Lake Park in 2021; Sx̱ótsaqel means "sacred lake" in Halkomelem. ^[3] The park is covered by an approved management plan for Chilliwack Lake. ^[2] The surrounding mountains form part of the North Cascades, which straddle the border with Washington State and surround the lake on all sides. ^[4] The south shores of Chilliwack Lake are protected as an ecological reserve. ^[5] The park is operated by Sea to Sky Park Services Ltd. ^[6]

Chilliwack Lake is the park's centrepiece, suited to motorboating, canoeing, kayaking, swimming, and fishing for Dolly Varden, kokanee, rainbow trout, and cutthroat trout. ^[1] Strong afternoon winds are common, and dangerous currents exist at the lake's outflow and several kilometres downstream, so only experienced paddlers should canoe or kayak here. ^[1] Three main trails share a trailhead at the Post Creek parking lot: Lindeman Lake (3.4 km return), Greendrop Lake (10.4 km return), and Flora Lake (14 km return), while the Radium Lake trail (16 km return) starts from the Chilliwack Lake campground. The park has about 40 km of trails in all, and the Trans Canada Trail winds through it. ^[1] The trail between Greendrop and Flora lakes has grown over and is difficult to follow, and it crosses several large landslides, so it should only be travelled by experienced backpackers. ^{[1] [2]} Routes to Hanging Lake and from Radium Lake to the Chilliwack Lake ecological reserve are not maintained by BC Parks and are in poor condition. ^[1] Horse use is allowed on the Trans Canada Trail only. ^[1] Downstream of the park, the Chilliwack and Vedder River is a popular whitewater kayaking and rafting destination. ^[3]

The park has 182 frontcountry campsites in five vehicle-accessible campgrounds (the Lindeman, Greendrop, Paleface, Flora, and Radium loops), as well as a playground. ^{[1] [2]} There are pit toilets in the day-use area and at each campground but no flush toilets or showers, and cold-water taps are located in each campground. ^[2] A gradual single-wide boat launch beside the day-use area is designed for boats under 20 feet long. ^[2] Backcountry camping, with eleven campsites at Greendrop, Lindeman, Flora, and Radium lakes, requires backcountry registration. ^{[2] [1]} The park is 64 km southeast of Chilliwack, 40 km in from Vedder Crossing along Chilliwack Lake Road. ^[1] The park gates are locked between 11 pm and 7 am daily. ^[1] The park road gate is open seasonally from mid-April to mid-October; for 2026 BC Parks lists the gate as open from 10 April to 18 October. ^[2] There is no cell phone reception past the On the Way store on Chilliwack Lake Road, and ATVs and other off-road vehicles are not permitted in the park. ^[1] The nearest services, including groceries and gas, are in Chilliwack, so visitors need to arrive well prepared.

BC Parks asks visitors to be aware of bears and other wildlife at all times and never to feed or approach them, and the Lindeman Lake backcountry site has a hanging bear cache. ^{[1] [2]} Flowers, trees, and shrubs are part of the park's natural heritage and must not be damaged or removed. ^[1] There is no camping and no fires on any lakeshore of Chilliwack Lake; all camping and fires are restricted to designated sites and rings, and fires are not permitted in the backcountry. ^[1] ATVs and other off-road vehicles are not permitted in the park. ^[1] Conservation priorities include protecting old-growth forest, wildlife habitat, and the ecological integrity of the Chilliwack watershed, which drains to salmon-bearing waters downstream. ^[3]
