Southwest Calgary Communities
If you're an avid Rocky Mountain visitor, you'll surely be interested in southwest homes for sale in Calgary. Getting to and from the foothills and Rockies to the west is quick to do and you'll avoid major traffic when leaving the city.
Many southwest communities enjoy beautiful landscapes with valleys and hills amid aspen groves and fresh bodies of water. Panoramic views of the mountains to the west or perhaps the downtown skyline to the east aren't unusual for many southwest Calgary homes for sale.
Downtown communities - located in the southwest quadrant - enjoy a convenient lifestyle close to where all the action happens in Calgary. Redevelopment in areas like East Village, Victoria Park and now plans for West Village are revitalizing the City Centre and infusing it with Western Canadian culture while creating new event and festival hubs in the process.
Highly sought-after inner city neighbourhoods like Altadore and Killarney offer the opportunity for an inner city lifestyle in a new infill development. Meanwhile, new suburban communities like Shawnee Slopes, Discovery Ridge, Walden and Aspen are all excellent places for families to grow and create lasting memories with one another.
Southwest Calgary Parks & Amenities
Southwest residents have ample access to some of Calgary's best private schools. Webber Academy, Calgary Academy, Rundle Academy and the Edge School for Athletes are just a few of the more prominent private schools and are a huge appeal to many buyers when browsing properties for sale in southwest Calgary.
Chinook Mall, Calgary's largest indoor shopping centre, is found a few minutes south of downtown on the corner of Glenmore and Macleod Trails. Southcentre Mall is a bit further south and is also an excellent mall with hundreds of restaurants, shops and services.
Repsol Sport Centre is located south of the Beltline in Lindsay Park and on the Elbow River. It's the largest indoor recreation centre in the city, but Cardel Rec South and Westside Recreation Centre aren't far behind in terms of facilities, programs and community involvement.
The Glenmore Reservoir, Weaslehead Flats and Fish Creek Provincial Park are the three largest outdoor recreational parks used by thousands of Calgarians daily. Fish Creek is also home to Sikome Lake, a man-made lake open for summer.
