Now is the time to take a kayak out in the majestic shadow of the Brooklyn Bridge. Free kayaking is offered on Wednesday, Thursday, and Saturday. There's a free kids-and-family paddle on Sunday, which allows kids aged 7 and older to paddle solo (as long as a guardian is present) with help from additional on-water safety boaters.
Brooklyn Bridge Park Boathouse's program takes place in a protected embayment between Piers 1 and 2 in Brooklyn Bridge Park with stunning views of the NYC skyline. They'll provide the boats, paddles, and life vests; you do the paddling.
Though kayaking is free, you've got to register in advance. Some walk-ups may be accommodated if there's space, but making a reservation here is key.
