If you remember the TV show “Full House” you would know this famous street. Although they do appear in many other TV shows and movies.
We caught the Muni to get to Alamo square. The park across from the houses can get crowed with tourist so I would get there early morning. We arrived around lunchtime in March however I think it would be a lot busier in summer.
There isn’t much to see other than the row of these Victorian Style homes so unless its just to say :”Been there done that” and you have limited time in San Fran I would use the time to see something else.
People still live in the houses so best to get there, take your photos and head off again.
