Only open 9a-3p on weekdays, the Boys & Girls club is a non-profit that has boat rentals available, so you can take a peek at the world from the water. Paddle around on the Mystic River for $ 10/hr, per boat, or half day/whole day pricing is available. If you’ve got a big group, call and ask about pricing and amount of people needed for group rates. There is a free parking lot attached to the building, tables and benches that you can eat lunch at.
