I wouldn't say this park, named after the Algonquian-speaking Nissequaq tribe, entails a hike. It's more of a quick walk through some pretty trees that you can do in flip-flops. It culminates by the Sound, where there's some sand to walk through and a bunch of boats and kayaks to look at. There's a small parking lot by the marina, and that's where people seem to start their kayaking down the river. The river was so nice to look at and walk by. The park is pretty underwhelming, but it's quiet and relaxing. It makes for a chill activity for twenty to thirty minutes. I was so disappointed that they didn't take my friend's military ID, which allows you to go to any state park for free. It's only an $8 park fee, but it's about the principle. That's literally what the park card is for. Also, there aren't any real bathrooms. There are a few port-a-potties. Overall, I definitely wouldn't say this park is worth a trip, but if you're in the area, I guess go for a low-key walk and glance at the river.

The park is very walkable and it has a lot of nice hiking trails and you can also launch your kayak. There is an area of abandoned buildings if you dare to go by them good luck. They might be haunted lol.

It's alright. Very short trail, less than a mile. Takes you to a small beach. Unfortunately no one there is wearing a mask, made me feel very uncomfortable. Just because you are outside doesn't mean coronavirus doesn't exist, people! Overall, this park is underwhelming. Few cool views and a few cool abandoned buildings but other than that it's more of a "I wanna go to the beach but the beaches are at capacity" type place.

I've heard quite a bit about this park, mostly from kayaking and canoeing enthusiasts, and it is a WONDERFUL spot to launch. While I was just home on LI for a quick visit, I was DYING for my trusty kayak, which sits sadly in the garage, gathering dust back home in Ohio. Nevertheless, this is GREAT spot to explore, and as you wander the grounds of this former (mental) institution turned wildlife preserve and bird refuge, your (over-active) imagination, if it's anything like mine, will take you in a million directions as you explore (from a distance) the abandoned hospital buildings and doctor/patient residences. Eerie, interesting, thought-provoking... Plenty to explore, both in nature, and how Mother Nature takes back even the most "ambitious" of our man-made creations. Without getting too philosophical about how we might "warehouse" our "undesirables," and spend zillions on the "latest and greatest" state of the art structures, only to find them "obsolete" a generation or two later, this is a fine park to explore, whether on the beautiful surrounding waterways or by foot or bicycle. Don't miss the informative visitor's center at the entrance, and if you're here like we were late summer, the BEAUTIFUL dahlia garden at the building's entrance. Worth a visit!!

This is one of my favorite parks. I've been going for years. Let me say though, the tall building others keep adding photos of, Building 93, it's not part of the park. It's across the street from the park and as cool as it is, it's off limits. If you get caught, you'll get a summons or arrested. Just a couple of weeks ago we saw a group of about 5 young people getting rounded up by cops for being inside. The park itself is quiet and eery. There are buildings left over from the old Kings Park Psychiatric Center (which closed down in 1993) that remain scattered across the property, both in the park and outside it. They are in varying states of decay and awesome to look at and wonder about the stories that lie within the walls. On the park side you can freely walk around outside the buildings, but going inside isn't permitted (and watch out for poison ivy growing all over the buildings' facades). Unfortunately (in my opinion at least), they've started tearing buildings down. I know they are becoming increasing unsafe so I do understand why, it's just a bit sad. A short time from now barely any remnants of the dark but fascinating history will remain. I'm glad I've been photographing it over the years. It will be interesting for the park to transform as we see most of the Doctors Housing has now been demolished and is being replace with a pavilion and picnic area (so it seems from the work being done). I will just miss some of those old buildings. There is a playground, a small one. There's lots of areas to walk around, including a hiking trail. There's also kayaking/canoeing in the on-season. It's really quite a neat park all around. I only wish they could have figured out a way to save more of the buildings and make it part of the attraction permanently (like eastern state penitentiary). It has been a lot of years though, so I guess things can't always stay the same.

What a better way to start the year then with a group hike. They have facilities which were pretty clean which was great. We took the white trail and it was nice and not very hard. The only thing I didn't like is that part of the hike you have to walk on the road by a very nice private neighborhood. Even if the neighborhood was nice and quiet I prefer to have my hike fully in the woods.

First you see this

Hmm yes this is a park but it's a park on the grounds of the former Kings Park Psychiatric Center! The grounds are expansive. A good part overlooks the water, you can see The Bluff and some of the town beaches from certain spots. There are bathrooms located inside the visitors center building located near the playground (Northern end of the park). There's a playground, trails, but you are surrounded by the old, creepy psych center buildings! There were lots of people of all ages walking around everywhere. Growing up in the area I'd say now it definitely has become an even bigger hot spot for explorers and photographers. All I can say is, yes the views are nice when looking towards the water but there's just such a creepy, nightmare like feeling all over the place! I also hope that there isn't an extreme amount of lead and or asbestos in the air. The buildings are abandoned and falling apart. People love exploring them (the ones that are still standing). It's interesting, check it out!

Pleasant park to visit in Kings Park located right off the grounds of the abandoned Kings Park Psychiatric Center campus. You'll see many closed off buildings that are pretty creepy given the dark history of the hospital. Follow the trails along the bluffs over looking the Long Island Sound and the mouth of the Nissequogue river. Best to enjoy in the spring and fall when the weather is nicer. There is some construction currently underway since they're knocking down some of the old buildings so be mindful of that. Also note, don't even think about entering the grounds off 25A after dark. Suffolk Police are waiting right at the entrance and you will be ticketed so any thrill seekers or paranormal buffs looking to check out the abandoned buildings at night will be caught. Nice park to visit and recommended.

There is an old hospital there with a bunch of other abandoned buildings. There is also a couple of marinas. Many people get creeped out by the abandoned buildings but I think the one is really cool will all the art on the windows.

Building 93

Building 93 is one of the most astounding abandoned buildings I've ever seen. I had seen plenty pictures of this state park but until I drove up and stood there, looking up at it with my own two eyes, I hadn't understood exactly how massive it was. My hair stood on end the second we turned the corner and I saw it. The entire park is covered with so many huge buildings, all abandoned and the decay is pretty advanced. The cold January day my friend and I visited it was completely overcast - making the atmosphere even more eerie. Sure, there's plenty of big abandoned buildings out there but 13 floors of psychiatric hospital remains - that's crazy!

One of the condemned buildings soon scheduled for demolition. Taken with a Gopro.

I agree with the other reviewer. It's very eerie. It's sad too. The history is depressing and disturbing. No matter how tempting, it's best to avoid entering any buildings because of asbestos. I don't know how much exposure it takes but why bother. If you're riding a bike or walking through any of the rooms, you'll make contact with lead paint, dust, and who knows what else. But do explore the now silent, serene grounds and views while they're still around.

Very neat park and the psychiatric asylum is certainly harrowing thing to see and walk past.

I've passed this hidden gem THOUSANDS of times, and while back in NY for a long weekend finally…read moredecided to check it out. Though I grew up less than 15-20 min. away, this beach was not in my township (Huntington) so we stuck to our own local N. Shore Long Island Sound beaches (rather than pay a craaazy entry fee). Off season, everyone's a resident of everywhere/anywhere, so a beautiful, sunny February afternoon was a PERFECT opportunity to check out Callahans. We had the whole place to ourselves, and my sister and I checked out the upper picnic area, the new/improved playground, and the wonderful views around the perimeter of the parking lot. Rumor has it there are other trails, but we did not see them, so we ventured down to the entrance to the beach to get a closer look at the BEAUTIFUL views... NOTE: I don't believe you can park in the little circle near the stairs leading down to the beach, though strangely enough, there are handicapped parking spaces there. This beach is many things: scenic, secluded, convenient if you live in the area, great for families, picnics, and golf fans, but it is definitely NOT handicapped friendly, unless you just plan to enjoy the view from above. There are MANY steps to get down to that beautiful beach, and you'd better be in reasonably good shape AND not forget anything in your car, because it's a TRIP up and down those stairs. While my sister and I didn't find the hiking trails that are supposedly there, we did hike the full length of the beach, a WONDERFUL walk all the way to neighboring Sunken Meadow State Park beach and back. BEAUTIFUL, invigorating, and very do-able, nearly 3 miles back and forth. Well worth the "ride!!" Some of the best things/places on Long Island are still free, especially if you go off season... Check this place out!!

Nothing good to say about this beach.Parking is far from beach area the. After walking to beach…read morearea you have to tackle the stairs going down then after a few heart attacks the beach area is dirty and water dirty with floating it looks like used condoms. Where did my tax dollars go besides the steps and the asphalt area above where lifeguard station is. My last time there!
