Mercer Island

Located at 3600 East Mercer Way on Mercer Island, this public boat ramp provides access to Lake Washington's East Channel beneath the I-90 bridge. The concrete ramp features two lanes and is 16 feet wide, accommodating kayaks, canoes, and motorboats. A day-use fee applies for launching. The site is situated within Aubrey Davis Park, offering nearby amenities and parking.

Be aware that construction activity is currently underway in the area as part of a wastewater system upgrade. You may encounter flaggers and alternating traffic on the road leading to the launch, though boat ramp access is being maintained. Check ahead for any updates on access conditions before your visit. The East Channel provides paddlers with direct access to the broader Lake Washington system.
