The resort spans the Niagara Escarpment near the southern shore of Georgian Bay, and encompasses 147 hectares (360 acres) of skiable terrain with a vertical drop of 220 metres (720 ft).

In 2000, construction began on its resort village, made possible after Intrawest acquired a 50 per cent stake in the company the year prior.

Some suggest that the description of the Blue Hills, a hilly area with a village by a lake, could also apply to other Petun settlements in the region.

The ski train service was briefly discontinued in 1943 due to logistical needs of the Second World War.

In 1953, the Weider opened Blue Mountain Pottery in order to support the resort's finances during the skiing off-season.

This includes the installation of four chairlift in 1960s, the completion of Blue Mountain Inn in 1963 and the Central Base Lodge in 1969.

To finance this development, Weider sold off Blue Mountain Pottery in 1967, although retained the 4.0 hectares (10 acres) of land located across the pottery factory, opting to build a large restaurant, shopping centre and planetarium near the resort.

During the 1970s, three additional chairlifts were installed, along with the resort's first snowmaking guns and lighting for night skiing.

[4] In 1977, Blue Mountain introduced its first summer attraction, the "Great Slide Ride", featuring two parallel concrete tracks.

[10] Additional summer attractions were added at the resort in the 1980s with the installation of tennis courts, waterslide, and the acquisition of Blue Mountain Beach at Georgian Bay.

[4] In 1999, Intrawest acquired 50 per cent ownership of Blue Mountain Resorts from the Weider family.

[8][10] The resort also expanded its summer offerings in the 2000s with the addition of an open-air gondola in 2005, an aquatic centre in 2006, an alpine coaster in 2010, along with a putting green and zip lining.

[4] In February 2013, the resort announced the Orchard section of the mountain would be developed to include six additional runs and a six person high-speed chairlift.

Construction began in the spring of 2013 and was completed early in the 2013-2014 ski season, The total cost of the expansion was $10 million.

[14] The resort has a skiable area of 147 hectares (360 acres) made up of 43 named ski trails, which includes four terrain parks.

Specifically, the area's underlying soft rocks eroded away quickly, which caused the more resistant caprock to break off and created the cliff-life slope.

As a result, the area rises at a rate of 15 centimetres (5.9 in) every 100 years due to post-glacial rebound.
