I don't remember Kali being listed as "open seasonally" last year. Regardless, the safest bet is that if something is listed as being "open seasonally" that we not rely on it being open, unless we're going during the Summer peak season.
maybe the seasonally thing is new. we went in jan a few yrs ago and it was open. usually value season means open seasonally stuff is not open ( at least that has been our experience)
