Last Mountain Lake is located in south-central Saskatchewan with the south end of the lake approximately 45 kilometres northwest of Regina. The lake averages 3 Km in width and spans west and north for over 85 Km.  Last Mountain Lake was formerly referred to as Long Lake.  The northern tip of Last Mountain Lake is home to Last Mountain Bird Observatory. Reserved by the Canadian government in 1887 as a natural wildlife area, it is the first federal bird sanctuary reserve in all of North America.
Today, the area at the northern end of Last Mountain Lake is designated as a "Wetland of International Importance". This area is known as a migratory stop for over 280 species of birds and a breeding ground for as many as 100 different species. The south end of the reserve is located approximately 8km north of the Sunset Acres Resort along the lake's shoreline.
