Trails for hiking/running near campus?

<p>I was curious if there are trails for running and hiking near campus, and if they are also used for hiking and running in the winter.</p>

<p>There are trails at Edgewood Park and West Rock/East Rock park, but they aren't walking distance from Yale. East Rock is close if you take a shuttle to Whitney Ave where a lot of grad school apartments are.

<p>For running, most people either go to East Rock (which is pretty far) or just run up past Science Hill. It's an urban environment, so there aren't that many parks to run in. I'm not sure how many people actually use Edgewood Park, but Science Hill is a popular running destination.</p>
