Along the east side of the village, heading north, is Avonlea Creek. Avonlea Creek is a tributary of the Moose Jaw River and it joins the Moose Jaw River near Rouleau. About 5 kilometres (3.1 mi) south-east of Avonlea, is Avonlea Dam, which was built on Avonlea Creek between 1963 and 1964, creating the Reg Watson Reservoir. The reservoir is the village's only water source.
Avonlea Heritage Museum houses many artifacts from the area in the train station, and contains an indoor Main Street, agricultural displays as well as murals by accomplished local artist Paul Geraghty.
Avonlea Badlands are four kilometres away to the west on private land. Guided tours are available through the museum.[7]
The picturesque Dirt Hills[8] to the west are home to natural flora and fauna. The Dirt Hills are the largest push moraine in the world.[9]
