San Francisco is a vibrant city with many iconic places to visit. Read the main San Francisco article here.
You can just walk around through the main walkway and enjoy the bustling activity or you can stroll along the outside pathways with a great view of the bay, Alcatraz, and passing cruise ships.
Deeper into the pier, you can get the “7D Experience" - a roller-coaster, 3D movie, laser tag experience all-in-one.
While at the pier, don’t forget to try the Musical Stairs where you can make music by going up and down the stairs.
For the young and young at heart try the Carousel or catch a puppet show.
One of the biggest attractions at the pier is the large population of Sea Lions that made the docks their home. Just walk to the edge or sides of the pier and enjoy the boisterous Pinnipeds and their antics.
Also close to the pier you can rent a bike for a whole day or go on a guided bike tour. I suggest doing both a cruise and bike tour to see the Golden Gate Bridge from all angles.
Pier-39 has a lot of dining options including restaurants with amazing views of the bay. My favorite at the pier is Neptune’s Waterfront Grill & Bar. It has good food and the best view.
