Sawhill Ponds Wildlife Preserve

The Sawhill and Walden Ponds Loop offers a delightful escape into a reclaimed wetland ecosystem in east Boulder. You'll stroll along predominantly flat, wide paths, often crushed gravel, with boardwalk sections providing intimate views of the water, especially near Cottonwood Marsh. The scenery is defined by numerous ponds, creating beautiful reflections of the surrounding trees and distant foothills, making it a serene experience for all.

This easy 3.5-mile (5.6 km) hike, with only 24 feet (7 metres) of elevation gain, typically takes about 1 hour and 25 minutes. It's a fantastic option for families, birdwatchers, and anyone looking for a gentle nature walk. While the trail is generally well-maintained, be mindful that winter conditions can bring snow and ice to certain sections, so plan accordingly.

What truly sets this trail apart is its transformation from former industrial gravel pits into a thriving wetland habitat, now renowned as one of Boulder's most important birding locations. Keep an eye out for a wide array of bird species, along with garter snakes, frogs, and turtles. The area's accessibility and connection to other nearby trails also make it a versatile choice for a quick outing or a longer exploration.
