The Fernhill Wetlands loop offers a delightful escape into nature, winding through serene marshes, vibrant water gardens, and alongside Fernhill Lake. The flat terrain, a mix of paved and gravel paths, makes for an easy 1.9-mile (3.1 km) jog, perfect for spotting diverse birdlife and enjoying the peaceful wetland scenery. You might even catch a glimpse of distant peaks like Mt. Hood on a clear day, adding to the picturesque views.

Parking is ample at the trailhead, and you'll find restrooms and picnic areas available for convenience. This easy route, with only 11 feet (3 metres) of elevation gain, takes about 19 minutes to complete, making it a great option for a quick, accessible outing. Remember that dogs and bikes are not permitted on the trails to protect the local wildlife.

This area is a remarkable example of ecological restoration, transformed from former sewage lagoons into a thriving wildlife sanctuary and natural water treatment system. It's a significant stop on the Pacific Flyway, attracting thousands of migratory birds, especially between November and March, making it a prime spot for wildlife spotting while jogging.
