The serene Japanese Stroll Garden is seemingly hidden in plain sight.

3. Japanese Stroll Garden – Mill Neck

A quick jaunt through the foothills of Mill Neck brings you to an authentic tea house in the middle of the John P. Humes Japanese Stroll Garden. Center your inner om and enjoy the Japanese landscape and meditative experience along the way. The elevated stepping stone paths might be a bit wobbly for little feet. You could easily drive right past the unassuming gates, so keep your eyes peeled for this incredible, weekends-only, walk-through experience that’s open from April through October.

4. Jones Beach Nature Energy Center – Wantagh

The Nature Center in Jones Beach State Park is an engaging spot for families to experience nature up close and hands-on.

It’s FREE to visit, however, some programs incur a fee.

7. Belmont Lake State Park – North Babylon

At Belmont Lake, you can pedal your boat, making this an ideal watersport for families with multi-aged children.

There is so much to see among the 216 acres of this nature preserve. Kids can travel through a labyrinth, see reflections in a massive garden globe, and explore some of the prettiest landscapes the area has to offer. While this site is FREE to visit, note that it is closed on Mondays.

9. Prosser Pines Nature Preserve – Middle Island

The tall pines (as in Long Island Pine Barrens) make this Long Island spot particularly unique. You feel like you’re in a magical forest with trees seemingly reaching as tall as the sky. Search for teepees to explore along this 3/4-mile loop trail, which is an easy route to run or walk. The trail is open year-round and pets are welcome. You’ll find a similar setting in the adjacent Cathedral Pines.

10. Elizabeth Alexandra Morton National Wildlife Refuge – Sag Harbor

One of the most unique experiences in a completely natural setting on the South Fork, the birds at this refuge eat right from your hand. Bring a baggie of bird seed and see if you can identify which little winged ones land for a visit. Walk the flat trail to an expansive beach with sweeping views of Sag Harbor. This is the perfect place to plop for a picnic before your hike back home, and it’s open year-round.

11. Holtsville Ecology Site – Holtsville

A leisurely walk through the well-kept, stroller-friendly grounds at one of our favorite local petting zoos reveals more than 100 animals including a bobcat, buffalo, bald eagle, American black bear, and more—all of which are injured or non-releasable. Bring your camera because the kids will want a photo of their little faces poking through the large “photo-op” board where they will appear to be farmers or farm animals. Pack a picnic lunch, and plan on a visit to the playground before heading befor home. This FREE eco site is open daily year-round, with some exceptions.

Facilities are open seasonally and pets are not permitted on the ocean beach from mid-March through Labor Day.

17. 67 Steps Beach – Greenport

Just below the rolling grounds of the Horton Point Lighthouse is 67 Steps Beach. It’s a steep walk down the rocky shoreline of the Long Island Sound, but totally worth it.
