Does one need to pay to see yoganandas tomb?

No !!! Just let security know you’re visiting yogonanda . Walk up to the security booth in the main entrance of the mausoleum and tell them you’re their to visit yogonandas tomb and they’ll clear you . Yogonanda was a spiritual guru with lots of followers forest Lawn Cemetery claimed his body knowing this so they have to let you in just follow their rules .

I believe he is in a private mosuleum. But you don't have to pay to enter the cemetery.
