Craigleith Provincial Park, Provincial park at Blue Mountain shore, Ontario, Canada.

Craigleith Provincial Park is a recreation-class provincial park on the southern shore of Georgian Bay, 10 km west of Collingwood in The Blue Mountains, Ontario. Its shoreline is made of fractured plates of oil shale rather than sand, and the park preserves this rare geological feature. The park lies north of Highway 26, with the park office near Blue Mountain ski resort.

Craigleith Provincial Park was created in 1967 by Regulation 245/67, Schedule 59 of the Provincial Parks Act, from two parcels along Highway 26 and land along a former railway line; only the land north of Highway 26 became the active park. From 1859 to 1863 William Darley Pollard ran the Craigleith Shale Oil Works east of the park, extracting bituminous oil shale until inefficiency closed production shortly after 1863. The Craigleith Shale Oil Works Historical Plaques in the park mark this episode.

The park takes its name from Craigleith, the historic oil-shale works site; plaques in the park mark the Craigleith Shale Oil Works, which operated from 1859 to 1863 under William Darley Pollard. Visitors can also see remnants of the steamer Mary Ward, which grounded here in 1872, and park brochures remind them that removing shale is illegal.

The park is open from May to October, and day-use visitors must leave by 10 pm, after which only registered campers stay overnight. The campground has 172 sites, 66 with electrical service, plus a comfort station with showers, laundry and flush toilets; drinking-water taps stand outside the day-use area. The Park Office sits on Highway 26 near Blue Mountain ski resort, and firewood is sold at the gatehouse beside the Park Store.

The steamer Mary Ward ran aground off this shore in 1872 after its captain mistook a tavern light for the Collingwood harbour light; eight people died, and barrels of oil and furniture drifted onto the Craigleith beach. When the bay froze, men with horses salvaged what they could.
