Introduction
Exploring San Diego may be an endless adventure, but there are limitations, especially if you don't have a car. San Diego is more a chain of separate communities than a cohesive city, and many of the major attractions are separated by some distance. Walking is good for getting an up-close look at how San Diegans live, but true Southern Californians use the freeways that crisscross the county. Interstate 5 runs a direct north-south route through the coastal communities from Orange County in the north to the Mexican border. Interstates 805 and 15 do much the same inland. Interstate 8 is the main east-west route. Routes 163, 52, and 94 serve as connectors.
If you're going to drive around San Diego, study the map before you hit the road. The freeways are convenient and fast most of the time, but if you miss your turnoff or get caught in commuter traffic, you'll experience a none-too-pleasurable hallmark of Southern California living -- freeway madness. Drivers rush around on a complex freeway system with the same fervor they use for jogging scores of marathons each year. They particularly enjoy speeding up at interchanges and entrance and exit ramps. Be sure you know where you're going before you join the chase.
Public transportation has improved a great deal in the past decade: the San Diego Trolley, which runs as far south as San Ysidro, has expanded in the north from Old Town to beyond Mission San Diego and San Diego State University; commuter Coaster trains run frequently between downtown San Diego and Oceanside, with convenient stops in Del Mar, Encinitas, Carlsbad, and other charming coastal towns; and the bus system covers almost all of the county. Making connections to see the various sights is time-consuming, however. Note that Fashion Valley shopping center, Old Town, and downtown are the three major bus transfer points, but because many of the city's attractions are along the coast, and the coast is itself a major attraction, you'll be best off staying there if you're carless.
The bike-path system is extensive, the weather is almost always bicycle-friendly, and lots of buses and trolley cars have bike racks, so two-wheeling is a good option for the athletic. The great distances between sights render taxis prohibitively expensive for general transportation, although cabs are useful for getting around once you're in a given area. Old Town Trolley Tours has a hop-on, hop-off route of popular spots around the city, but it takes so long to cover the route that you're unlikely to see more than two areas in one day.
San Diego County's warm climate nurtures some amazing flora. Golden stalks of pampas grass grow in wild patches near SeaWorld. Bougainvilleas cover roofs and hillsides in La Jolla, spreading magenta blankets over whitewashed adobe walls, and when the jacaranda trees that line the streets in Cortez Hill and nearby neighborhoods bloom in spring, spreading vivid, shady canopies, downtown is a vision in purple. Towering palms and twisted junipers are more common than maples or oaks, and fields of wild daisies and chamomile cover dry, dusty lots. Red-and-white poinsettias proliferate at Christmas, and candy-colored pink- and yellow-flowered ice plants edge the roads year-round. Jasmine blooms on bushes and vines in front yards and parking lots, while citrus groves pop up in unlikely places, along the freeways and back roads. When the orange, lemon, and lime trees bloom in spring, the fragrance of their tiny white blossoms is nearly overpowering.
Unless you're on the freeway, it's hard not to find a scenic drive in San Diego, but an officially designated 52-mi Scenic Drive over much of central San Diego begins at the foot of Broadway. Road signs with a white sea gull on a yellow-and-blue background direct the way through the Embarcadero to Harbor and Shelter islands, Point Loma and Cabrillo Monument, Mission Bay, Old Town, Balboa Park, Mount Soledad, and La Jolla. It's best to take this three-hour drive, outlined on some local maps, on the weekend, when the commuters are off the road.
