Landsburg bridge to Maplewood Roadside Park

The Cedar Rivers is the site of the annual Cedar River Slalom race typically held in late March every year. For additional information see League of Northwest Whitewater Racers site. The race course is set up as a permanent whitewater slalom training site that is maintained by local volunteers throughout most of the year. Good flows begin with the fall rains and continue through the spring. For those who run the river, small boulders provide good eddies and ample opportunities for practice. Some sections pass through braided channels that can collect wood debris and paddlers need to be aware of wood hazards particlarly at higher flows. King County has purchased a number of parcels along the river that are now managed as natural areas with forest restoration actively underway in the riparian corridor. As you approach Renton evidence of human impacts becomes more evident. This lower section is a bit easier in terms of whitewater and sometimes used by instructors working with beginners. Access Logistics: To reach the Landsburg Whitewater Slalom Course, the uppermost put-in, take Exit 17 (Front Street) off I-90 in Issaquah. Drive south on Front Street through downtown Issaquah. Although the road changes names a few times, continue south for 12.5 miles until you reach the Landsburg Bridge, which crosses the river. Along the way, you’ll pass under Highway 18 and the Hobart store/post office. For those planning to run the river, you can go from Landsburg down to Lake Washington, with several access points along the way. A popular intermediate access point is Rotary Park, located at the Highway 169 bridge near the junction with Highway 18. This access point is 7.5 miles into the run. If you wish to run the lower section (an additional 9 miles), there’s a take-out on the right bank at Maplewood Roadside Park, located about a mile east of the Highway 169/I-405 junction. Refer to the map for additional access points near bridges along the route.
