There are several stairways into the park along its length and we started on 14th street, near one end. (above is a view across the river from where we started.) The entire length of the High Line is about 1.5 miles so we probably walked about 1.25 miles of it. I was so overwhelmed I started taking pictures immediately and pretty much didn't stop the whole walk! Since it was such a nice day there were lots of people walking, but luckily not so many that I couldn't stop for pictures. There is greenery everywhere and sections of track that were left and planted around, which is so cool.
Besides the green space that's been created (there were actually some flowers in bloom!), another really cool thing for me was seeing the city from this perspective. We were a story or two up most of the time, possibly higher depending on what areas the trail was going through, and it's very interesting walking through the city at that level! You walk by people's balconies and patios, above busy streets and intersections, right by what are probably people's home or office windows, and also by some abandoned or busted up buildings/neighborhoods, which I love seeing. Really a great way to see the city. We had views of the Empire State building in the distance from some parts of the trail too.
Oh! And there was this bank of bird houses, designed like a shiny metal linear sculpture. The pictures I took don't really give the right perspective on how it was set up - it's positioned at maybe a 30-35 degree angle to the ground even though the picture below makes it look like it's standing straight up, but it was a really interesting design, and the birds were happily using it despite tons of people gawking at them.
We walked along the entire length to the opposite end at 30th street. At that end, you can see the next length of track they are working on to add to the trail. I don't know how far this particular rail keeps going but I hope they're able to convert the whole thing to add to this wonderful park. So much fun to walk it! We don't visit the city very often but I would absolutely come back here, maybe during the summer or fall when more of the flowers are blooming (there is also supposedly a water feature I don't think we saw, probably too early in the season for it). Here are a few more random pics from the walk.
I will have a more complete flickr gallery of this trip up shortly - here's the link and I will be adding photos to this shortly to complete it. I would absolutely recommend checking out the High Line to anyone visiting NYC and looking for an interesting urban adventure, complete with green space!
