The Last Mountain Regional Park Nature Trail, a self-guided walking trail, is an ideal site for birdwatching as it is situated in the Last Mountain Lake National Wildlife Area, North America's oldest bird sanctuary. The area is a popular migration point for thousands of birds every year, including pelicans, alder flycatchers, herons, orchard orioles, wood thrushes, tundra swans, western kingbirds, whooping cranes, yellow-rumped warblers and Swainson's hawks, just to name a few.

The Nature Trail features beautiful scenery, a bison rubbing rock and a bird blind that provides fantastic birdwatching opportunities. The trail also starts at the Nature Centre, which is located near the Last Mountain Bird Observatory, Saskatchewan's only bird monitoring station. The observatory is a member of the Canadian Migration Monitoring Network and is responsible for observing, catching and banding birds that migrate into the area in the spring and fall. Visitors are encouraged to stop by the observatory in May, August and September after travelling the trail in order to help with the banding and monitoring process.

An entry fee is charged to visitors entering the Last Mountain Regional Park, but there is no fee for participating in the Last Mountain Bird Observatory's activities. The trail takes roughly 2 hours to complete.
