San Francisco is a compact city of steep hills and fog, squeezed onto a peninsula between the Pacific and the bay. It is a place where a sunny morning can turn to a gray afternoon in minutes, and where the neighborhoods are more distinct than in most American cities. Walking is the way to see it, and the hills are the price you pay.

When to go

Fall (September to November)
Clear, warm days and mild nights. The fog pulls back and the city sees its sunniest weather. The summer crowds are gone, hotel prices drop slightly, and street festivals fill the weekends. This is the season to pick.
Winter (December to February)
Cool and rainy. Storms pass in 2 to 3-day spells, and the hills can be slick with leaves. Holiday lights and markets lift the mood, and hotel rates are at their lowest. If you like a quiet city and do not mind drizzle, it is pleasant. Bring a proper raincoat.
Spring (March to May)
Rain begins to taper by April. The streets bloom with wild mustard, and the parks get their green color. Crowds are still moderate, though spring break weeks can fill hotels. The Bay water is too cold for swimming no matter the season.
Summer (June to August)
Fog is the defining feature. Mornings are often gray and cold, the sun does not arrive until the afternoon, and the temperature rarely passes 20°C (68°F). This is the busiest and most expensive time for tourists. If you want warmth, skip it, or head east along the bay.

Getting your bearings

San Francisco sits on a 7 by 7-mile square at the northern end of a peninsula. The Pacific Ocean is to the west, the bay to the north and east. The city's center for visitors is Union Square, a small plaza surrounded by hotels, stores, and skyscrapers near Market Street. Two or three miles to the northeast, the Embarcadero runs along the bay with the Ferry Building at its center. North of that are the hills: Telegraph Hill, Russian Hill, and Nob Hill, with North Beach between them and the waterfront. To the south of Market, a flat district calls SoMa. Further south and east lies the Mission, a working-class area of murals, taquerías, and one of the few flat spaces in the city. The parklands of Golden Gate Park and the neighborhoods of the Richmond and the Sunset take up the far western side. You can walk from Union Square to the Ferry Building in 25 minutes, and from the Ferry Building up to North Beach in another 20. The hills make things seem longer than the distance suggests.

Getting around

Muni buses and light rail run day and night, with fares of $2.50 for a single ride and $8 for a cable car. The network reaches all corners of the city, but buses are often slow in traffic. BART connects downtown to the East Bay and the airport for $2 to $10 depending on distance. A Clipper card is the reusable fare card, but you can also tap any contactless credit card on Muni machines. Walking is usually the fastest way over short distances, particularly between Union Square, Chinatown, and the waterfront. Rideshares cost $10 to $20 for a short trip, more if you are on the opposite side of town. Driving your own car is a hassle, and downtown parking garages charge $8 to $15 per hour.

Where to stay

Union Square and the Financial District
The hotel core, built around a central plaza. It is the busiest, most touristy part of the city, with high-rise hotels, chain stores, and a constant flow of people. You are close to Muni, BART, and the cable cars, and you pay extra for that.
North Beach and Chinatown
Two neighborhoods crammed together on the slope below Telegraph Hill. North Beach is Italian cafés and old bars, Chinatown is crowded alleys with hanging lanterns and produce markets. Both feel like a different city from downtown, and both are within 15 minutes of Union Square on foot.
Fisherman's Wharf and the Marina
The waterfront strip from Pier 39 to the Wharf's shell of souvenir shops. It is the most tourist-heavy place in the city, and the food is not great. The adjacent Marina is a quiet, sunnier district with a long green and a view of the Golden Gate; staying there is more peaceful.
The Mission
South and east of downtown, this once-working-class district is now the city's Latin and food heart. The streets are flat, sunny, and covered with murals. You will find taquerías, night clubs, and a steady crowd of students and tech workers. It is the best base for cheap food and nightlife.
The Richmond and the Sunset
Two mirror-image residential districts on the Pacific side of the city. They get less fog than the middle of town, have their own markets, and are close to Golden Gate Park and the ocean. Staying here means a longer commute to the sights but a lower hotel rate.
SoMa
South of Market Street, it is a flat land of warehouses, lofts, and museums. The Museum of Modern Art, the Contemporary Jewish Museum, and the tech campuses sit here. It is convenient for the Moscone Center and a 10-minute walk from Union Square, but empty on weekends.

A day here

A Bridge and a Burrito: One Day in San Francisco

  1. Golden Gate BridgeWalk the span before 9am when the fog is still low. The crossing is 1.7 miles each way; allow an hour with photos. Free to walk. Bikes cost about $35 for a day and can be taken across and around the park. The walkway is sometimes closed during storms, so check the weather.
  2. Palace of Fine ArtsA 40-minute walk or 10-minute ride from the bridge through the forested Presidio. The 1915 leftover is free to view from the outside. It is a popular photo stop and a quiet place to sit for ten minutes. Inside is small and not worth the admission.
  3. Lunch in the MarinaThe neighborhood just east of the Palace is full of outdoor cafés and modest prices. A sandwich and a drink will cost $15–25. There is a green space along the shoreline to eat on the grass. It will be sunny unless the fog is stubborn.
  4. Balmy AlleyIn the Mission, two blocks of painted murals that date to 1977. Take a rideshare from the Marina (25 minutes, $20) or a bus ride on the 30 line. The alley is free and open at all times; give yourself 20 minutes. The art changes as walls are repainted.
  5. Mission burrito dinnerOn the next block, a taqueria serves burritos the size of a forearm. A basic order costs $10–14. The line moves fast, and tables are shared. Go before 7pm or after 8:30pm to avoid the worst of the queue.
  6. Ice cream at the endA small shop around the corner scoops ice cream until 10pm. Two scoops cost about $5. There is a bench in the park in front, where the fog may be rolling in by dusk. It ends the day without needing to book anything.

Eating

Mission burrito
A flour tortilla wrapped around rice, beans, meat, and salsa, often grilled and wrapped in foil. The standard order at a taqueria in the Mission costs $10–14. It is heavy enough to be the only meal you need.
Sourdough bread
The tangy white bread that started in the 1849 Gold Rush bakeries. A warm loaf at a bakery will run you $5–8. The version at Boudin Bakery near the wharf is a tourist attraction in itself; the chowder is the same loaf hollowed out and filled for about $12.
Dungeness crab
In season from November through June, the large sweet crab is boiled, cracked, and served with lemon and butter. Vendors on the wharf charge $20–30 for a whole crab. Ask whether the season is open before ordering; when it is not, the crab is frozen and not worth the price.
Dim sum in Chinatown
Small plates of steamed dumplings and buns served on carts. A full brunch for two will cost $40–60, or $3–5 per plate if you share. The best tables book early; go at 10am on a weekend to see the full carts.
Oysters from the bay
The local Miyagi oysters are small and briny. A half dozen at a counter near the Ferry Building costs around $20. The farmers markets on Tuesdays and Thursdays are the cheapest place to get them.
North Beach pasta
Italian-American cooking, a relic of the city's postwar Italian neighborhood. A plate of spaghetti with clam sauce costs $20–30. The portions are large, and the service is often brisk.

Practical

Money
The currency is the US dollar. Credit cards are accepted nearly everywhere, even for a $3 coffee. Tipping is standard at 15–20% for sit-down meals and a dollar a drink at bars. Sales tax is about 8.5% at the point of sale. A basic meal in a sit-down restaurant costs $20–35; a beer is $7–10; a cappuccino is $5.
Transport
Muni buses and light rail cost $2.50 per ride. Cable cars cost $8. BART crosses to the East Bay and from the airport for $2–10 depending on distance. A Clipper card is the rechargeable fare card, but all Muni vehicles and BART stations accept contactless credit cards at the same fare. Rideshare cars to a neighboring neighborhood cost $10–15; a trip from downtown to the Golden Gate Bridge costs about $25.
Safety
The city has a visible street population, especially in the Tenderloin and around Market Street. Car break-ins are a known problem, so do not leave anything in a parked vehicle. The majority of violent crime is not aimed at tourists, but keep your phone in your pocket and stay aware after dark. The Mission and the Marina feel safer than the immediate downtown core.
Opening hours
Most shops open between 10am and 6pm, with malls staying later. Museums often close on Mondays. Restaurants generally serve lunch from 11:30am to 2:30pm and dinner from 5pm to 9pm; a few stay open later. Golden Gate Park is open from sunrise to 10pm, and certain gardens have separate hours. The cable cars run from 6am to midnight.
Seasons
Fall (September to November) is the warmest and clearest time. Summer has fog, winter has rain, spring is a middle ground. Hotel prices mirror the weather: they peak in summer, drop in the depths of winter, and recover around holidays.

Worth knowing

  • Bring a light jacket in every season; the fog often rolls in in the afternoon, even on a clear morning.
  • Car break-ins are common; treat all parked cars as empty and avoid renting if you can.
  • Most neighborhoods have one free museum day per month, so plan around those if the entry fee matters.
  • The city is hilly. A bus ride is often quicker and more comfortable than walking.
  • For the widest views, go on a clear day after a cold front; the air is crisp and the fog is gone.

Questions

How many days is enough for San Francisco?
Three full days gives you the major neighborhoods, a bridge crossing, and a sit-down meal. With five, you can add a day trip to Muir Woods or Sausalito. A single full day is rushed but doable.
Is San Francisco expensive?
It is one of the most expensive cities in the US. A hostel bed is $60–100, a mid-range hotel $250–400, a basic restaurant meal $20–30. You can trim those numbers by staying outside downtown.
Is San Francisco walkable?
Downtown and the eastern neighborhoods are very walkable, with many districts within 20-30 minute walks of each other. The hills are steep, so the next tram stop or a bus may be welcome. A cable car ride is a tourist event, not a commute.
Do people speak English?
English is the common language on the street and in shops. Spanish, Cantonese, and Mandarin are widely spoken in the Mission and Chinatown. Almost all menus and signs are in English.
Is it safe at night?
Most of the city is safe, but downtown has a high rate of car break-ins and street disorder, especially in the Tenderloin. Areas like the Mission and Marina have active nightlife and are generally fine. Keep your phone out of sight and avoid the Tenderloin's dark side streets.
Is it worth visiting in winter?
Winter is the rainy season. Rain can fall for days at a time, and the afternoon fog can set in early. If you do not mind wet shoes, you get low crowds and lower hotel rates. December's lights in the neighborhoods are a charm.
