In this guide
San Francisco is a small city, about seven miles across, so you can see a lot in a short trip. The catch is that it is hilly, the weather changes by neighborhood and the best-known sights sell out. A little planning makes a big difference.
This guide is the starting point for everything else on the site. For specific sights, see the San Francisco attractions hub. For transit details, read getting around San Francisco.
When to visit
Summer is the busiest season, but it is often not the warmest. Fog pushes in from the ocean on many June, July and August days, and afternoons near the water can feel cold and windy. September and October usually bring the clearest skies and the warmest weather of the year.
Winter is the rainy season, with most of the year’s rain falling between November and March. It is also quieter, hotels tend to be cheaper outside the holidays, and the city is green after the first storms. Spring is mild and good for walking, with wildflowers in the parks and fewer crowds than summer.
See San Francisco weather by month for average temperatures and a packing list, and the San Francisco events guide to line a trip up with a festival or parade.
How long to stay
Three full days is enough for the bridge, Alcatraz, a cable car ride, Golden Gate Park and a couple of neighborhoods. Four or five days lets you slow down, add a museum or two and take a day trip to Muir Woods, Sausalito or the wine country north of the city.
A simple three-day plan
- Day one: the waterfront. Start at the Ferry Building, walk the Embarcadero to Pier 39 and the sea lions, take your booked Alcatraz ferry from Pier 33, and finish in North Beach for dinner.
- Day two: the bridge and the Presidio. Walk or bike from Crissy Field to the Golden Gate Bridge, cross on foot, then head to Lands End and Ocean Beach for sunset.
- Day three: parks and neighborhoods. Spend the morning in Golden Gate Park, then walk through the Haight, Alamo Square and the Mission, with a stop in Dolores Park.
Where to stay
Union Square and the Financial District are the most central and have the most hotels, with easy access to BART, Muni and the cable cars. Fisherman’s Wharf is popular with families and close to the Alcatraz ferry, but it is quieter at night and farther from most restaurants. Nob Hill, North Beach and Hayes Valley are good picks for a more local feel.
Our where to stay in San Francisco guide compares each area, including which blocks to avoid at night.
Getting there
San Francisco International Airport (SFO) is about 13 miles south of downtown. BART runs from the International Terminal to Powell Street and Embarcadero in about 30 minutes, and a ride to downtown costs $11.80. Tap a contactless card or phone at the fare gates, or use a Clipper card.
Oakland International Airport is across the bay and also connects to BART. Rideshares and taxis are easy from both airports, but traffic on the freeways can double the travel time at rush hour.
Getting around
You don’t need a car in the city. Parking is expensive and hard to find, and car break-ins are common in tourist areas. Muni buses, light rail and historic streetcars cover the whole city, and a single Muni ride is $2.85 with Clipper or a contactless card. The cable cars are $9 a ride.
Visitor Passports for unlimited Muni and cable car rides are sold for 1, 3 or 7 days through the end of 2026, but SFMTA plans to end them in January 2027. Our cable car guide covers the lines and the fare changes.
What to book ahead
- Alcatraz. Tickets sell out, often weeks ahead in summer and on holidays. They go on sale up to 90 days in advance. The island is closed for dock repairs from October 26 to November 18, 2026.
- Muir Woods. You need a parking or shuttle reservation before you go.
- Popular restaurants, especially on Friday and Saturday nights.
- Big events such as Outside Lands and the Dickens Christmas Fair.
The Alcatraz tour guide explains which tour to pick and how to avoid fake ticket sellers.
Budget tips
San Francisco is expensive, but many of the best things cost nothing. Walking the Golden Gate Bridge, the views from Twin Peaks, Lands End, the murals in the Mission and most of Golden Gate Park are free. Some museums have free days, and the de Young’s tower is always free.
See free things to do in San Francisco and free museum days for the full lists.
Staying safe
Most visits go smoothly. Keep valuables out of sight, and never leave anything in a parked car, even for a few minutes. Parts of the Tenderloin and the blocks around Sixth and Market can feel rough, especially after dark, so stay alert or take transit through them. At the beach, the water is cold and Ocean Beach has strong currents, so swimming there is not a good idea.
Avoiding the tourist traps
Some of the most famous stops are crowded and overpriced. You can still enjoy them with the right timing, and some have better alternatives a short walk away. Our San Francisco tourist traps guide goes through them one by one.
