San Diego
A big city that behaves like a string of surf towns, under about the steadiest climate in the United States.
San Diego sits in the far southwestern corner of the mainland United States, a low, spread-out city of mesas and canyons wrapped around one of the Pacific coast's finest natural harbours. It behaves less like a single metropolis than a chain of beach towns, canyon suburbs and a compact downtown, held together by a climate that barely shifts from month to month. It is a Navy town and a border town as much as a holiday one, and the Mexican influence on its food, language and streets is not a garnish but the foundation.

Why you'll love San Diego
The climate famously even Pacific mildness, which makes every month of the year a reasonable month to come
The coast a long chain of distinct beaches, each with its own town, pier and surf break attached
Food the fish taco in its home town, Baja-inflected Mexican cooking across the whole city, and one of the densest craft-brewing scenes in the country
Culture in a park one of the largest urban cultural parks in the United States, packing more than a dozen museums, gardens and theatres into walking distance

When to avoid San Diego
No bad season here - the coast stays mild all year and the only real quirk is the marine layer locals call May Gray and June Gloom, when late-spring and early-summer mornings sit under low cloud that usually burns off inland by midday but can hang over the sand all day. July and August are the warmest and by far the busiest stretch, when American school holidays fill the beach suburbs.
Top things to do in San Diego
-
Balboa Park - museums, gardens and Spanish Revival architecture
culture arts history 👍 PopularA vast park on the mesa above downtown, built around the ornate pavilions of the 1915 Panama-California Exposition. More than a dozen museums line the El Prado promenade, alongside the lath-domed Botanical Building and its lily pond, the Japanese Friendship Garden, the Old Globe theatres and an outdoor pipe organ that gets played in the open air on Sundays.
-
San Diego Zoo - canyon enclosures inside Balboa Park
nature wildlife 👍 PopularGrown out of animals left behind by the 1915 exposition, and one of the first zoos anywhere to build open, moated, cageless habitats instead of bars. It rolls over a hillside of planted canyons, with an aerial tram running overhead and koalas, pandas-era primates, big cats and a serious botanical collection along the way.
-
Coronado Beach and the Hotel del Coronado - the wide sand across the bay
scenic history 👍 PopularA broad, pale, mica-flecked beach backed by the red-turreted 1888 wooden hotel that put the place on postcards and later on film. The village behind it is low-rise and walkable, and the arrival by ferry across the bay beats the drive over the bridge.
-
La Jolla Cove - sea lions, kelp beds and sea caves
nature wildlife scenic ⭐ Highly recommendedA pocket of sandstone coves where sea lions haul out on the rocks and harbour seals take over the Children's Pool beach during pupping season, in full view and full smell of the clifftop path. The water offshore is a protected reserve, so snorkellers and kayakers get kelp forest, leopard sharks in the warmer months and a line of sea caves under the headland.
-
Cabrillo National Monument - tide pools and the view down the bay
scenic history ⭐ Highly recommendedThe tip of the Point Loma peninsula, marking where Juan Rodriguez Cabrillo made European contact with this coast in 1542. The 1855 Old Point Loma Lighthouse stands on the ridge with the whole bay, city and border laid out below it, the ocean side drops to rocky tide pools at low water, and grey whales pass offshore on their winter migration.
-
USS Midway Museum - walk the flight deck downtown
historyThe aircraft carrier moored at Navy Pier on the Embarcadero served from 1945 to 1992 and is now open from the hangar deck up. You work through berthing spaces, the galley, the brig and the island bridge before coming out on a flight deck lined with restored aircraft, with the working naval harbour all around.
-
Old Town San Diego - the adobe blocks where California began
historyThe original pueblo below the Spanish presidio, preserved as a state historic park of adobe houses, a schoolhouse, stables and courtyard restaurants from the Mexican and early American decades. Touristy, unapologetically so, but it is the oldest settled ground in California and the mission that started the chain sits a short way up the valley.
-
Sunset Cliffs Natural Park - the Point Loma clifftops at dusk
scenicA stretch of crumbling sandstone bluffs on the ocean side of Point Loma, with arches, blowholes and narrow stairways down to the rocks. It is the city's default sunset spot for good reason; stay back from the edges, which genuinely give way.
-
Torrey Pines State Natural Reserve - sandstone bluffs and the rarest pine in America
nature wildlife hiking scenicWind-bent Torrey pines, which grow wild almost nowhere else on earth, cling to eroded gold-coloured badlands above the sea. Short trails loop past the sandstone formations and drop down to the wide beach below, where you can walk back along the shore at low tide.
-
Mission Beach and Belmont Park - the boardwalk and the wooden coaster
scenicA sandbar suburb barely two blocks wide, with the ocean on one side, the calm water of Mission Bay on the other, and a paved boardwalk running the length of it up to Pacific Beach and the Crystal Pier. The 1925 Giant Dipper still rattles along the beachfront in the middle of it.
-
Windansea and the town beach breaks - surf San Diego
surfingWindansea's reef break under La Jolla, with its palm-thatched surf shack, is the storied one, and Blacks Beach below Torrey Pines picks up serious size off an offshore canyon. Beginners belong instead at Mission Beach, Pacific Beach or Tourmaline, where the schools work gentler sandbars. Winter brings the bigger northwest swells and colder water; late summer is small, warm and friendly.
-
Fish tacos and Baja-style Mexican - the city's signature plate
foodThe battered fish taco crossed the border here and became a local institution, and the wider Mexican scene runs from carne asada burritos in Barrio Logan, under the mural-painted bridge pillars of Chicano Park, to the taquerias strung along the south bay. Order at the counter, eat standing up, do it more than once.
-
North Park and Miramar breweries - the craft-beer city
foodSan Diego brews at a scale few American cities match, with West Coast IPA effectively invented in this county. The tasting rooms cluster in two places: the walkable 30th Street corridor through North Park, and an industrial grid inland at Miramar that locals treat as a crawl by designated driver.

Getting to & around San Diego
Getting there
Fly into SAN on the edge of the bay, barely 5 km from downtown, or ride the coastal Pacific Surfliner in from Los Angeles
Flight
San Diego International Airport (Lindbergh Field) (SAN)
One of the shortest airport runs of any American city: the single runway sits on the bay just northwest of the centre, with approaches dropping low over the Bankers Hill rooftops. Rideshare or taxi reaches the Gaslamp Quarter in about 10 min, a shuttle links the terminals to the Old Town Transit Center for the trolley and Amtrak, and a city bus runs along Broadway through downtown.
Train
Santa Fe Depot
Amtrak's Pacific Surfliner runs down the coast from Los Angeles and Santa Barbara into the tiled 1915 Santa Fe Depot downtown, one of the better rail arrivals in California; Coaster commuter trains come in from the north county beach towns
Drive
Interstate 5 runs the coast from Los Angeles in roughly two to three hours depending on traffic and continues south to the Mexican border; Interstate 8 comes in from Arizona and the desert
Coach
Downtown
Long-distance coaches from Los Angeles, Phoenix and Las Vegas terminate downtown near Santa Fe Depot
Border crossing
San Ysidro
Arriving from Mexico, most people walk across at San Ysidro, one of the busiest land crossings in the world, and pick up the Blue Line trolley straight into downtown; the Cross Border Xpress footbridge connects a terminal on the San Diego side directly to Tijuana's airport
Cruise
B Street Pier
Ships berth at the downtown cruise terminal on the Embarcadero, a short walk from the Gaslamp Quarter
Getting around
MTS Trolley
Light rail links downtown with Old Town, Mission Valley, the university and, on the Blue Line, the border crossing at San Ysidro; it is the piece of transport visitors actually use
TBC
Bus
Fills in Balboa Park, Point Loma and the beach suburbs the trolley misses, though it is slow going across a city this spread out
TBC
Car
The honest default. This is a freeway city, and the north county, the back country and the further beaches all get much easier with one; downtown parking is the painful part
TBC
Coronado ferry
A short crossing from the downtown piers to Coronado's Ferry Landing, and much the nicest way over without driving the bridge
TBC
Rideshare and taxi
Uber and Lyft blanket the metro and the airport run at all hours
TBC
On foot and by bike
Downtown, Little Italy, Balboa Park and the beach villages are each walkable, and a near-continuous path runs the sand from Mission Beach up to Pacific Beach
Free
Day trips from San Diego
Tijuana, Mexico
Full dayBorder city
Mexico starts at the end of the trolley line: Avenida Revolucion, the Baja food and wine scene that shaped San Diego's own cooking, and the spherical dome of the Cultural Center. Take your passport, check what your nationality needs to re-enter, and expect the northbound queue home to be the slow part.
Getting there
train | walk
About 45 min on the Blue Line trolley to San Ysidro, then cross on foot
Julian
Full dayMountain apple town
A gold-rush town at around 1,300 m in the Cuyamaca mountains, built on apple orchards and pie, with pine and oak forest trails in the state park nearby and the occasional dusting of snow in winter.
Getting there
car
About 1 hr 15 by car east into the mountains
Temecula Valley
Full dayWine country
Southern California's main wine region: several dozen cellar doors across dry rolling hills, hot-air balloons up at dawn over the vineyards, and an old-west main street of boardwalks in town.
Getting there
car | tour
About 1 hr by car north
Anza-Borrego Desert State Park
Full dayDesert badlands
California's largest state park: slot canyons, a palm oasis walk up Borrego Palm Canyon, rusted metal sculptures of prehistoric beasts scattered across the valley floor, and after a wet winter a desert wildflower bloom.
Getting there
car
About 2 hr by car east over the mountains
Carlsbad and the north county coast
Full dayCoastal towns
Encinitas, Cardiff and Carlsbad string north with mellow surf breaks, surf-town main streets, a hillside of flower fields in spring and a Lego theme park that anchors many a family trip. The train runs right along the shoreline.
Getting there
train | car
About 45 min by Coaster train or car up the coast
San Diego Zoo Safari Park
Half dayOpen-range wildlife
The zoo's inland sister park in the San Pasqual Valley, where rhinos, giraffes and antelope range across large open enclosures crossed by a tram. A genuinely different day out to the city zoo, and better for hoofed animals.
Getting there
car
About 45 min by car northeast to Escondido
A little history of San Diego
The Kumeyaay have lived across this coast, its river valleys and the back-country mountains for thousands of years, in a territory that runs straight through what is now the international border. European contact came early and then stalled: Juan Rodriguez Cabrillo sailed into the bay in 1542, the first European to reach the coast of present-day California, and nothing was built for another two and a quarter centuries. In 1769 a Spanish expedition raised a presidio and Mission San Diego de Alcala on the hill above the river, the first of the twenty-one California missions and the start of colonial California.
The pueblo below the presidio, today's Old Town, passed to independent Mexico in 1821 and to the United States after the war that ended in 1848. The city then moved: a speculator named Alonzo Horton bought waterfront land in the 1860s and laid out the downtown grid that is still there. Two world's fairs in Balboa Park gave the city its Spanish Colonial Revival look, the Navy arrived for the deep harbour and the flying weather and never left, and aerospace, then biotech and telecoms, built the modern economy on top.

FAQs about San Diego
▸ When is the best time to visit San Diego?
There is no bad month; this is about the steadiest climate in the United States. Spring and autumn are the sweet spots, warm and clear and quieter than high summer. Late spring and early summer mornings often sit under the coastal marine layer that locals call May Gray and June Gloom, which usually burns off inland by midday but can hang over the beaches all day. July and August are the warmest, sunniest and busiest, and the ocean is at its warmest from late summer into early autumn.
▸ How many days do you need in San Diego?
Three days covers Balboa Park and the zoo, the downtown waterfront and one full beach day. Five lets you split the city properly, a couple of days around downtown and the park and a couple out on the coast between Point Loma and La Jolla, and still fit in a run to the mountains, the desert or across the border.
▸ Do you need a car in San Diego?
Mostly yes. The trolley and buses handle downtown, Old Town, Mission Valley and the border run perfectly well, but the city sprawls and the beaches, the north county and the back country are all much easier with a car. If you are basing yourself downtown or in one beach suburb and not roaming, you can skip it.
▸ Is San Diego good for families?
Exceptionally. Between the zoo, the Safari Park inland, the marine park on Mission Bay, the Lego park up the coast at Carlsbad, calm bay beaches for small children and a huge park full of museums, few American cities make it this easy.
▸ Can you visit Tijuana as a day trip?
Yes, and plenty of people do it as a half day. The Blue Line trolley ends at the San Ysidro crossing and you walk across in minutes. Bring your passport, check what your nationality needs to re-enter the United States, and plan for the northbound queue back to be the slow part of the day.
▸ Is the ocean warm enough to swim?
Cooler than most visitors expect, because this is a cold-current coast. Late summer and early autumn are the warmest and comfortable without a wetsuit for most people; through winter and spring most surfers wear one, and families tend to swim in the shallower, calmer water of Mission Bay instead.
▸ Is San Diego expensive?
It is a costly Californian city, especially for accommodation in summer and anywhere near the water. The redeeming part is how much of the best of it is outdoors and free: the beaches, the Balboa Park grounds and gardens, the Point Loma clifftops, the Torrey Pines trails and the La Jolla coast path. Eating well is cheap if you eat like a local, because the city's signature food comes from taquerias.
