Hi. No, it is definitely not possible to walk to the boardwalk from 90th St. 90th St. is about 5 miles from the boardwalk or more.
The boardwalk ends on 27th St, and the rides and amusements are all located below 1st St. There is a public bus that you can ride that runs about every 15 minutes and costs $1.00 per ride or $3.00 for a ride all day pass. And there is plenty of parking at the Cropper Inlet Parking Lot or on any of the side streets around the boardwalk. Most of the street parking is metered. The bus runs 24 hours a day.
90th St. is an excellent area to stay. Plenty of restaurants and nice beach.
Merci for your question!
