Breakneck Ridge is another excellent option for a hiking day trip out of NYC, and you can get there on the Metro-North or simply by driving for about an hour out of the city. This hike climbs up and up, so you'll need to have some energy bars on hand to make it to the top, but you'll be rewarded with some amazing views. The hike runs for about four miles in total and is well-suited to people with a moderate level of physical fitness. Map
