The old rail lines have been repurposed into an ever growing luscious flowering wonderland in the bustle of the city. Recycling at its best. I love how they kept some of the rail lines intact though and planted in and amongst them.
It's neat to walk elevated through all of the buildings while still in a park that is a mile and a half long.
If you are planning a trip to NYC anytime soon, I highly recommend walking the High Line! It was great to walk with kids too. My girls loved looking at the flowers, climbing on the benches and just plain old people watching. We can't wait to go back!
ps- if you are planning on going with kids, check out this book, The Curious Garden by Peter Brown and read it before you go. It is a children's book inspired by the High Line and now one of our favorites.
