The North path access point is on 179th so if you're coming up Ft Washington make a left on 179th onto Cabrini Blvd and you'll see the steps to access the path, there are a few flights to go up to the walkway on the ramp then more to get on the actual bridge walkway. The more dangerous option is to get on the vehicular on ramp (bearing right on the wide shoulder of course) and getting on to the ramp walkway to spare yourself the first batch of stairs.

The south path access point is off 178th and Cabrini Blvd and just has a ramp with a hairpin turn. This is always the best option but as I mentioned in the previous post, it is closed on weekdays until July.
