New York is a maritime city, carved up by rivers, dotted with historic ports and accented by marshland. But if you’re like most New Yorkers who aren’t ferry commuters, houseboat residents or fishing enthusiasts, the city’s waterways are often an afterthought.

For decades, our waterways were known less for their breathtaking vistas and more for toxic waste, illegal dumping and sewage outflows. But years of improvement to wastewater management, 75 million dutiful toxin-absorbing oysters and boatloads of extracted ‘black mayonnaise' have combined to give us the cleanest waters in a century. Cue soaring music and the eerie calls of whales and dolphins, who are returning to New York Harbor's cleaner waters in scores.

Enjoy what your great grandparents couldn’t and get out for a paddle! Ok yes, raw sewage spews into the rivers any time there’s more than a tenth an inch of rain, so maybe save the boating adventure for a dry day.

Here are a few places to get out on the water this summer across the five boroughs.

Manhattan

Inwood Canoe House

Inwood Canoe House offers free kayaking sessions every Sunday morning. You have to sign up in-person at 9 a.m. and the 20-minute guided paddles start at 10 a.m. You have to fill out an online waiver before you arrive. For questions, email inwoodcanoe.openhouse@gmail.com.

Downtown Boathouse, Hudson River Park

Instead of cocktail hour, how about catching the sunset beyond the Hudson River from a boat. Several times each week through October 10th, the Downtown Boathouse lends out its kayaks on a first come, first serve basis for 20-minute jaunts along the Hudson River for free. They’re open during weekends and holidays from 10 a.m. to 4:30 p.m. and on Tuesday and Thursday evenings from 5:30 p.m. to 7 p.m. No reservations needed.
