Pro tips
Don't underestimate the fog.
While April is generally clearer than summer, the famous San Francisco fog can still roll in quickly, dropping temperatures significantly. A warm outer layer is paramount.
Embrace public transportation and walking.
The Muni system is excellent, and many attractions are walkable. Save yourself the headache of parking and enjoy the city like a local – but be ready for hills!
Book popular attractions in advance.
Alcatraz, Muir Woods shuttles, and popular restaurant reservations can fill up weeks if not months ahead, especially in the spring. Plan accordingly to avoid disappointment.
