I'm in the area & looking for something to do, an answer won't come in time for me but for others who might wonder; it's noted there's hours-closes at 2:30pm today (Monday 3/2/21) is it separate from the rest of the cemetery so you can ONLY go then?

I’m going to see Bruce Lee & his son Brandon Lee this weekend either on Saturday or Sunday

The grave sit is in the cemetery, a little ways up from the entrance. It's a beautiful area.

The grave sites are not separate from the rest of the cemetery. It is a gated cemetery though. If the gates are open, the cemetery is open. Hope this helps!

I think it was listed closed the time I went as well, I'd risk it
