Center for Wooden Boats
Though it used be considered an off-the-beaten-path gem, the Center for Wooden Boats is now a major feature of Lake Union Park. The center gives free boat rides on the lake every Sunday; they sail on the hour from 1 to 3 pm, but the first-come, first-served slots tend to go fast, so you should queue up at the Center as soon as it opens. You may also rent a variety of small craft—pedal boats, canoes, rowboats, and small sailboats—to explore the lake on your own (lessons are available if you don't have much experience). Rates are $25–$50 per hour. Check out the events calendar for weekend workshops or to schedule one-on-one sailing lessons.
