There are tours. No walking in to look around. Theres a little house to the south of the Whaley House next door. Walk in there to buy tickets.
You purchase your tickets next door and can use it anytime they are open that day. You'll just walk in and it's self guided.
They are open from 10 to5 I believe you are able to walk around and they have people there to tell you about the house.
