First actual experience ko rin sa lake when we visited in 2019! I'm not quite sure paano mag commute going there hehe both times kasi we've been there ay may sarili kaming dalang car hehe

What I do know though is there's a bus from Alabang going to SM San Pablo. From SM San Pablo yata there's another ride you need to take. I'll research about this one and get back to you hehe I'll update you on Discord
