Both our Year-Round River Trail and Seasonal Wetland Trail offer visitors opportunities to get up close in nature and experience a variety of habitats. Please note that our Seasonal Wetland Trail, open May 1 through September 30, is closed the rest of the year in order to protect important migratory waterfowl habitat.

Trail Name: Wetland Trail (Seasonal)

Open Season: May 1 – September 30 only; not open to biking or running.

Length: 3 miles

Location of trail: Trail begins next to the main parking lot (main trailhead), or at trailhead next to Visitor Center

Surface: Most of the trail is a service road that is a combination of loose gravel and natural material

Difficulty: Easy - moderate (with short sections of steeper grades) 

Information:  This trail is open seasonally in order to protect wintering habitat for waterfowl. The seasonal trail takes visitors closer to the wetlands, and offers close-up views of wetland habitat and wildlife, including marsh birds, turtles, and a variety of mammals and other birds. This trail is a service road, and can connect with the river trail (open year-round), or as a separate trail (portion of trail loosely parallels the year-round trail). Visitors can choose to walk the full trail to complete the loop. During the summer, weather conditions can be very hot, and there are limited opportunities to walk in shade and no benches located on this trail. 

Other Accessibility Information: Please note that visitors will see a descending short staircase near the trailhead to access the seasonal trail; in order to access this trail by wheelchair via the trailhead, visitors need to utilize a short connector trail from the year-round trail (from trailhead, continue on year-round trail, descend the short switchbacks, and the connector trail is just after the two ponds). Please call 503-625-5944 with any accessibility questions.
