I was a little disappointed given the rave reviews, but overall a pretty good beach and beach experience. Go at low tide, and don't drive home during sunset. Arrived at 1pm, 87 deg, Sat, July 3'rd.
To preface, I normally explore the North Shore beaches of Good Harbor and Plum Island (and Revere if forced to), so I can't speak to how Nantasket compares with other South Shore destinations.
Parking: $7 in a city lot that said "full", but let us in and we quickly found someone leaving. $20 in what I believe were private lots that had tons of spaces but not as close to the water. Very reasonable, very close, I did not look for free neighborhood spots because I think parking for under $10 is always reasonable.
Crowd: Crowded, lots of kids. This was a very disappointing surprise. The beach at hight tide is just a sliver of sand so people are squeezed close to the seawall. We had some kids playing inches from our heads, and I can't blame them, there was no where else to go. Not enough room to play frisbee or dribble a soccer ball. Running barefoot along the beach would be difficult. Bring headphones or ear plugs, not the beach for listening to the relaxing waves.
Water: Warm, Salty, Rocky at spots. All things are relative, but by New England standards this was very tolerable temperature for sea water. For reasons I can't explain, all three of of us found the water to be much saltier than Cape Cod or Cape Ann. I would love for someone to disprove or explain that to me.
The drive and Sunset: From Boston it's a long kinda boring drive past mostly strip malls and a few marinas. We had no traffic on 93 and it still took an hour. Driving further up the peninsula of Hull provides amazing views of Boston, the harbor islands, and plenty of cool houses. We didn't stay for sunset, and I wish we had. The summer sun sets right behind the skyline so instead or enjoying it we drove back with sun in our eyes. I recommend staying late, watching the sunset, then heading back toward the city.
Beach Walk: There are a few clam shacks, ice cream stands, souvenir shops, an arcade, and a mostly ignored merry-go-round. Nothing exceptional but very convenient if you already have parking, have to manage a bunch of rug-rats, or want to eat junk food. Clean bathrooms and open showers to rinse off were a plus. This seems like a big plus for parents.
I want to try this trip again taking the ferry and a bike. The beach is actually very long, but parking is restricted and patrolled to make most of the shoreline exclusive for locals. read more
