Is it possible to visit that place by using public transportation (LIRR and so on)?

I haven't seen any public transportation near it

No sorry

You can take the LIRR to Great River. I'm not sure if there's a bus from there but you could probably walk to the park in 10-15 minutes from there. I ride my bike and it takes five minutes from the station.

I didn't see any since it's the last exit off the parkway but I could be wrong

I think that there are some buses that have a stop there.

Galyna it all depends where u are coming from u but there are no trains near but buses pass by there

Yes, has plenty of parking spaces as well
