The Cloisters and Fort Tryon Park, Washington Heights
If you’re into medieval religious art, the Cloisters museum is one of the best places, if not the best place, in the US to take it in, since the whole museum was built in the architectural stylings of a medieval monastery. But if, like most people, you could kind of take or leave medieval religious art, a trip up to Washington Heights/Inwood is well worth it just to walk around the grounds of the surrounding Fort Tryon Park. With eight miles of pathways, and great views over the Hudson River, it’s one of the quietest, most relaxing green spaces in the city. It’s much further uptown than Central Park, which cuts away all of the crowds and tourists -- and getting there is half the fun, if you bike.
How to get there: The park is accessible off the A train, at 190th St. But the best way to get there is to bike up the Hudson River Greenway, which you can bike in an hour from Downtown, on almost uninterrupted greenway bike lanes for most of the way.
