I wasted time on may5th thinking that the park is open. In the website it is showing as open .. but when we went there it is closed. There is no proper customer care to get more details. We wasted whole day because of this

Hmmm, I'm reading on their website that they don't open until May 26th. It seems the error lies in the Google autogenerated hours which do list the park as open for business. I believe those are based on user submitted comments rather than any input from the park itself.

That's right. This place has NEVER opened any earlier than Memorial Day weekend. Frankly, I don't understand how you "wasted the WHOLE day." Did you show up at 5am then stayed and waited in the parking lot until midnight, hoping it would open?

I agree with William. The park typically opens around Memorial Day weekend. Their website does say May 26.
