The Hudson River Waterfront Walkway starts at Exchange Place in Jersey City and travels north to the George Washington Bridge in about 10.5 linear miles. All along the waterway are artifacts from the waterfront's past as a hub of intermodal transport and oddities of its new role as a financial center and high-end residential living. The HRWW is the easternmost section of the Liberty Water Gap trail, which eventually will create a hike and bike friendly path across New Jersey. Depending on the weather and time of day, the Walkway is crowded with joggers, workers taking a stroll, or mothers pushing strollers. You will need to watch for muggles at all times!
This is a great series to do on a bike. If you do not have one, you can rent a CitiBike near the Exchange Place PATH station near the southern end of the series or the Newport PATH station at the northern end.
The Lefrak Point Lighthouse is not an artifact from the past. Sam LeFrak was the visionary who built the Newport area starting in the 1980s. Depending on which story you choose to believe, it is either purely decorative, build to honor the Lighthouse Foundation that was a favorite of the LeFrak family, or used as a navigational aid for LeFrak's yacht into the nearby marina. It is not a functioning lighthouse but is quite attractive on the waterfront.
