Join a walking tour of the Willamette Confluence Preserve, which features extensive habitats that are endangered in the Willamette Valley, and includes six miles of river corridor, floodplain forest, wetlands, upland oak woodlands and native prairie. The Nature Conservancy is working with partners to reconnect the river to its historic floodplain across 20 ponds in this former gravel mining site. During this mostly flat walking tour, volunteer docents will highlight the conservation efforts, human history and natural wonders. The pace of this tour will be a leisurely walk for 3-4 miles. Please no pets. Pre-registration is required.
