Lid Park Tennis Courts in Mercer Island are a paddle lid lift! Two outdoor concrete courts with permanent nets, in ‘Good’ shape, rally from 7:00 AM to 10:00 PM with lights. Free, with street parking but no restrooms—keep it lean. Rain might drift in—soft paddles smooth the lake breeze. No cover, just a park vibe near I-90.
