After the full moon, when the tide is the lowest, you'll find a century of fossils from a gone NY, trails of washed-out rainbow colored bottles, a graffitied shipwreck buried by time. Hundreds of years of history written in the sand.
A spin around the park on a bike makes me feel good. One lap is about 6.13 miles. I've trained here for longer rides (including this London to Paris ride on a track bike that was 86 miles one day, rest on the second day, and 136 miles on the third day). I've sat there on a Sunday afternoon and have done as many as 10 laps (with rests in between). I switch in-between my carbon road bike and my steel track bike.
A place for when you only have a day and your soul needs the smell of an ocean breeze and to feel sand between your toes. You can watch all the craziness of Coney Island from across the water.
