Harbor Island Park

It was our first time here. I came with my 2 kids & they had a blast. The park had so many children & it's huge!

Very nice marina. Hosts modern facilities with an upgraded security system. Location can be easily found as it is just off the I95.

Had a great time here. They have swimming areas sectioned off and monitored by life guards. A splash pad and restrooms nearby. The little sea life building was cool to look at. Spent about 10 minutes in there seeing the local sea creatures.

20 minutes from the Bronx. They accept cash and cards. $12 parking (unless you get a seasonal permit). Must pay to park regardless if you're entering the beach, marina, playground, or sports fields. Follow the path on the left at the park entrance. It will lead you directly to the shack to pay for the beach entrance(behind the artillery sculpture).
Beach cost was $11 per adult, $8 kids (2-12yo), under 2 free. You can order food and they will bring it to you at the beach (mostly finger foods, iced coffee, etc). We brought our own food and a small canopy which is permitted as long as you do not block the lifeguards view. No alcohol allowed.

Its a great family beach. Visited on a Sunday around 11AM, 93 degrees out and it was busy but not crowded. Not one person played loud music. It was a very chill family vibe. Has a small sprinkler area. Showers were out of order but large clean bathrooms (men/women/family). The beach itself is small. From end to end maybe a 5 minute walk. There's a concrete path spanning across the beach so its easy to travel with a wheeled cooler, etc. There are ropes separating 3 sections as long as there's a lifeguard you can swim in that particular section. There's also rope separating the "deep" water which you can also swim in while a lifeguard floats around on a board.
I gave Harbor Island beach 5 stars despite it being a small beach and the water having a heavy "ocean taste". The environment, layout, and vibe were so fantastic, they superceded any negative feelings I had.

Harbor Island Park is an absolutely beautiful place to relax by the water. If you have a boat, you can launch it into the water at a reasonable cost. There are huge open fields, a beautiful beach and tennis courts! It’s a great reason to move to Mamaroneck!
