Every beach community is different in size & make up and I think that the Old Saybrook, Old Lyme & East Lyme beaches have their own unique features. I suggest visiting to make your own determination.
I have another question: How do these Old Saybrook beaches compare to the Old Lyme & East Lyme beaches?
I also am partial to Knollwood since I am a summer resident of that community. My kids, who are now older, had some of the best experiences of their lives there! The community offers tennis, basketball, and open area for play near the club house. The beach offers swimming, a pier where you can access the water & swim raft as well as a rock jetty where the kids love to crab, fish and find mussels and snails. Cornfield Point is very nice but the beach is smaller and more crowded. Indian Town has a very nice beach area and amenities such as boat and jet ski docks. Chalker Beach offers a community beach environment with club house and beach parking.
The town beach is located between Knollwood/Cornfield Point and Indian Town and offers low tide sand bars for longer beach walks! All are very family oriented. Are you looking to purchase or rent.
Remember that these are Long ISland Sound beaches so they are all quite small relative to say, Narragansett or South County, RI.
