A biologically diverse 320-acre wetland in the heart of urban Bellevue, Mercer Slough Nature Park is Lake Washington’s largest remaining wetland. The park provides a diverse habitat and is home to hundreds of species of plants and wildlife.


The slough itself is a canal that winds through the park and is best explored by kayak or canoe. A trip along the waterway offers views of great blue herons, bald eagles, jays, beavers, otters, wild iris, and water lilies. The canal is limited to human-powered watercraft, making for a peaceful experience. Canoes and kayaks can be rented at Enatai Beach Park. Visitors to the slough may launch their own watercraft from the Sweyolocken Boat Launch located within the park. For those interested in a more educational experience, park rangers lead guided canoe trips through the slough during the summer months from Enatai Beach Park.
