If you have an extra day, consider taking a day trip to Napa Valley or Muir Woods. For a shorter trip, you can spend half a day in Sausalito, a charming artist enclave across the Golden Gate Bridge. If you find yourself with limited time, prioritize the Golden Gate Bridge, Fisherman's Wharf, and Alcatraz Island, as they are the most iconic attractions in San Francisco. Remember to check opening hours and book Alcatraz Island tickets in advance, as they tend to sell out quickly.
