North Williamsburg
We started our day by hitting Smorgasburg, the Brooklyn Food Market that pops up every Saturday just steps away from the North Williamsburg ferry stop. After perusing dozens of vendors selling local foods and exotic delicacies, we bought Korean-style pork buns, Vietnamese noodles, a Mexican sandwich and a couple of fresh lemonades, and then settled on the shady lawn alongside the river for lunch. Smorgasburg was our favorite part of our day out on the East River, and arriving by ferry is definitely the best way to get there. If you go on Sunday, you'll find the Brooklyn Flea instead, but it's also lots of fun.

Williamsburg has many other fun things to do for families, including McCarren Park, bowling alley Brooklyn Bowl, cool kids' boutiques and places to eat.

Long Island City, Queens

From Williamsburg, we took the ferry north to Long Island City. Right by the ferry stop is Gantry State Park, a newly refurbished, 12-acre waterfront green space with a cute playground. However, we had a different destination and walked a mile along Vernon Boulevard to 5 Pointz, the outdoor graffiti "museum," where we checked out all of the works, and even saw several artists creating new pieces. Sadly all of the graffiti at 5 Pointz was covered over in November 2013 and the building is slated for demolition.

MoMA PS1 is also nearby, but instead of visiting we relaxed with cool drinks in the diner across the street, and then headed back to the ferry.

Dumbo
Brooklyn Bridge Park has been a top ferry destination for us for a few years now. You can head to the playground at Pier 1, cool off in the great sprinklers at Pier 6, relax in the park, and then reward yourself with a cone from Brooklyn Ice Cream Factory, our favorite ice cream in all of New York City. Of course, there are many other wonderful things to do in Dumbo with kids, like visit Dewey's Candy Store and various kids' boutiques.

Pier 11, South Street Seaport
There are lots of cool attractions at South Street Seaport, plus nearby East River Park is being updated with lovely parkland. Imagination Playground is just steps away from the ferry terminal, or you can stroll across town to Battery Park City's awesome playgrounds.

Governors Island
Governors Island (which the ferry only stops at on weekends) can be a day-long destination by itself, but we decided to end our day here. The isle offers free mini golf and tons of complimentary festivals and activities. Or you can just enjoy a light dinner by the water before returning home. You can get back via the the East River Ferry or one of the free Governors Island ferries, which run to South Street in Manhattan or Brooklyn Bridge Park.

As we sat on the boat and enjoyed the cool breeze and sun setting across the harbor, the guy next to me said, "This sure beats the subway." We had to agree.

Greenpoint
We didn't get off at the Greenpoint stop, but there are cool attractions here, including McGolrick Park, indoor play spaces like Play and Gym Park, and another Brooklyn Ice Cream Factory outpost.

Midtown
The ferry also stops at 34th Street in Manhattan with a free connecting bus service that loops through midtown.

Things to Know
Bikes and strollers are allowed on the ferry, but there is an additional fee for bicycles (unless you have a folding model): $1 per trip or $3 for an all-day pass.

The ferry runs approximately every half hour on the weekends, but river traffic can cause delays. Click here for the full schedule.

The ferry boards and unloads very quickly. In the afternoon at popular stops, there are sometimes more people waiting to get on than can fit, so make sure you arrive early and line up, otherwise you may have to wait.

You can buy tickets at any of the stops with a credit or debit card, or you can pay cash on the ferry, but the all-day pass isn't available on the boat. You must purchase that before you board.
