Me and my husband run there all the time. It goes pretty much-all the way around Manhattan, it has great scenery, and you can run or bike.
It is wonderful.
BC it is away from streets-take a partner for safety and cell phones, but I see a lot of girls running with just their dogs or by themselves, and that can be kind of scary-since it's next to woods & all... but besides that, it is AMAZING! and there are mile marks every 1/2 a mile so you can keep track of how far you are going.
I like it----will keep going back... with my husband of course:)
Check it out!
*You see chipmunks along the way, really. [depends on how big of an imagination you have]
*You can travel the solar system. It is really quite neat for the kids, but you have to walk the whole trail to see the whole system.
*Great trip of the Little Apple, better than Central Park.
*Great time to be "one" with nature.
*Come to Manhattan, its great!
