Central Jersey:

Keansburg, union beach, keyport have decent views from across the harbor.

Washington Rock in Green Brook but the skyline is def in the distance.

North Jersey:

South Mountain in south orange.. decent view from Essex county

Liberty State Park will get you nice and up close. And there Stevens campus in Hoboken which is amazing.

Spots all along JFK Blvd east in weekhawken, Union City, West, NY, north Bergen are spectacular.
