If you are across from Revere Beach Boulevard at the beach from Bianci's Pizza OR Kelly's Roast Beef? Then Revere Beach can be pleasant & quite convenient, believe it or not, that is, IF you can find a parking spot. Salisbury Reservation NOT Salisbury Beach itself (it's located before the amusement rides & beach area, as you drive toward the area) is quite the place these days. Actually BEFORE the mad rush begins, which is before the 4th of July and after Labor day, is the time to go here! It's got a fairly new "over the dune" boardwalk along this beach, that's just beautiful; you won't even think you're at Salisbury Beach when you see this part of it! It's been recently renovated and it's pretty nice. Here's info on it:
Salisbury Beach is one of the state's most popular ocean beaches stretching for 3.8 miles along the Atlantic Ocean. This Salisbury Reservation's 521-acre park offers swimming, boating, fishing and camping. Facilities include a 484-site campground with renovated bathhouses, an extensive day-use parking lot, three new comfort stations for the beach going public with over the dune boardwalks, and a new playground and pavilion area. The facility also has two boat ramps that are located on the Merrimack River at the campground's southern edge.
In the fall and winter, harbor seals often sun themselves on the jetty. The town of Salisbury has many fun activities to offer for kids of all ages; with a large amusement park and video arcades.
In the Fall people sometimes head to the Salisbury Reservation early on Sunday mornings for walking and they'll see horseback riders along the beach.
Hampton Beach is another place that has a boardwalk as the previous poster mentioned:

If you really want to explore, you could check out Old Orchard Beach in Maine's boardwalk:

Then in Newport, RI., they have Easton's (First Beach) with a boardwalk:
Welcome To Easton Beach.com, Newport Rhode Island...
Their famous Cliff Walk starts here:
This walk remains one of the top attractions in Newport and is taken by people of all ages. The walk starts at the western end of Easton's Beach (Newport's First Beach) at Memorial Blvd. and runs south with major exits at Narragansett Ave., Webster St., Sheppard Ave., Ruggles Ave., Marine Ave., Ledge Rd., and Bellevue Ave. at the east end of Bailey's Beach.
Newport, RI's Cliff Walk combines ocean views, mansions, and a rocky shore line into a 3.5 mile walk.
ALSO, Bearskin Neck at Cape Ann's Rockport is pretty neat, you could take the commuter rail from North Station to get here, instead of driving, (since the gas is so ridiculous these days!) ALSO you could take the "downeaster" to Old Orchard Beach as well right from Boston.
