100 Mile Marsh is a small wetland area popular for birds and birdwatching, especially water fowl. Depending on the month, depends on the birds spotted in the marsh. The wetland marsh is located on Highway 97 in the town of 100 Mile House, British Columbia, Canada.
Circling the marsh is an interpretive walking path leading to some viewing benches and a grassy picnic area located near the highway entrance. The picnic area, just off the highway, is also the location of some historic artifacts and a First Nation teepee.
