California is the most populous state in the country and arguably its most cinematic, home to a coastline that runs from redwood forests to desert beaches, a wine region that rivals anything in Europe, and two of the most famous entertainment industries in the world. From the cell blocks of San Francisco's Alcatraz Island to the film studios of Los Angeles, the granite cliffs of Yosemite, and the vineyards of Napa Valley, California packs more distinct landscapes and cultures into one state than most countries manage. Whether you are searching for the best tours in California, tickets to top California attractions, the best places to visit in California, or simply the most memorable things to do in California, this guide covers everything worth knowing before you go.
San Francisco's Alcatraz Island held some of the most notorious federal prisoners in American history, including Al Capone, and its abandoned cell blocks are now one of the most visited sites in the National Park System. The ferry ride out into San Francisco Bay offers close-up views of the Golden Gate Bridge before docking at the island, where an audio tour narrated partly by former guards and inmates walks visitors through the cell house. Alcatraz tickets combined with a bay cruise are one of the most popular ways to see both the island and the city skyline from the water in a single outing. Tickets to Alcatraz sell out days or weeks in advance during peak season, since the National Park Service caps daily visitor numbers.

General admission tickets include the full backlot tour, and VIP options add access to real sound stages and prop warehouses not open to standard ticket holders. Beyond the studio, the Hollywood Walk of Fame, the TCL Chinese Theatre, and the Griffith Observatory overlooking the Hollywood Sign round out the classic Los Angeles itinerary, and the Getty Center offers a quieter, free alternative for art and architecture.

Most first-time visitors concentrate on Yosemite Valley, a seven-mile-long glacially carved canyon that holds the park's most famous viewpoints within a relatively compact area. Full-day guided tours from San Francisco are a popular option for travelers without a car, though the roughly four-hour drive each way makes an overnight stay a better fit for anyone who wants more than a few hours in the park. Multi-day tours pairing Yosemite with a night at Yosemite Lodge are widely available for travelers who want to see more of the park beyond the valley floor.
Book a Yosemite Day Trip from San Francisco →Napa Valley produces some of the most respected wine in the world, and its roughly 400 wineries range from small family operations to grand estates built specifically for visitors, many offering tastings, tours, and vineyard views within an easy day trip of San Francisco. Neighboring Sonoma County offers a similar wine experience with a more rural, less polished feel, along with its own historic town square dating to California's Mexican era. Guided wine tours with a picnic lunch are one of the most relaxed ways to visit multiple wineries without worrying about driving between tastings, and the Napa Valley Wine Train offers a different, more scenic way to sample the region from a vintage rail car.
Book a Napa Valley Wine Tour →San Diego pairs a famously mild, sunny climate with Balboa Park, a 1,200-acre urban park often described as the Smithsonian of the West for its concentration of 17 museums alongside the world-famous San Diego Zoo. The zoo's naturalistic habitats and conservation work with endangered species have made it one of the most respected zoos in the country, and its sister property, the San Diego Zoo Safari Park north of the city, offers a more expansive, drive-through style experience. San Diego Zoo tickets include access to the full grounds, and combination tickets covering both the zoo and Safari Park are available for travelers with more than a single day in the city.
Book San Diego Zoo Tickets →Joshua Tree National Park sits at the meeting point of the Mojave and Colorado Deserts, named for the twisted, spiky yucca trees that Mormon settlers thought resembled the biblical figure Joshua raising his arms in prayer. The park's boulder fields, popular with rock climbers, and its exceptionally dark night skies, far from any major city's light pollution, make it one of the best stargazing destinations in Southern California. Jeep and SUV tours departing Palm Springs cover more ground than a typical rental car day trip and usually include stops at Keys View, Hidden Valley, and Skull Rock. Nearby Palm Springs adds a completely different draw, with mid-century modern architecture, natural hot springs, and a well-preserved downtown built around the desert resort era of the 1950s and 60s.
Book a Joshua Tree Jeep Tour from Palm Springs →Big Sur is the roughly 90-mile stretch of coastline between Carmel and San Simeon where Highway 1 clings to cliffs hundreds of feet above the Pacific, widely considered one of the most scenic drives in the world. McWay Falls, an 80-foot waterfall that drops directly onto a beach inside Julia Pfeiffer Burns State Park, and the Bixby Creek Bridge, one of the most photographed bridges in California, are the two stops most visitors prioritize along the route. Guided half-day tours from Monterey are a good option for travelers who would rather not navigate the narrow, cliffside road themselves, and pairing Big Sur with nearby Carmel-by-the-Sea and the Monterey Bay Aquarium makes for a full day along the Central Coast.

The median household income is $100,149, and the largest racial and ethnic groups are Asian (15.3%), White (33.8%), Hispanic (40.2%), American Indian and Alaska Native (1.2%), and Black or African American (5.2%). The median age is 38.4 years. Approximately 11.8% of residents live below the poverty line, compared to the national rate of 12.2%. California's economy, the largest of any U.S. state and among the largest in the world, is anchored by technology in Silicon Valley, entertainment and media in Los Angeles, agriculture in the Central Valley, and a substantial tourism industry built around its coastline, national parks, and wine country.
Fall (September through November) is the best time to visit California. The best time to visit California overall. Summer crowds thin out, temperatures are comfortable statewide, and Yosemite and Napa Valley are both near their best, with grape harvest running through October. Spring (March through May): Wildflowers bloom across the desert parks like Joshua Tree, waterfalls in Yosemite are at their fullest from snowmelt, and coastal cities avoid both winter rain and summer fog. Summer (June through August): Peak tourist season statewide, with warm weather nearly everywhere except coastal cities like San Francisco, which is often foggy and cool even in July and August. Mountain destinations like Lake Tahoe and Yosemite see their heaviest crowds. Winter (December through February): The rainy season along the coast and ski season in the Sierra Nevada, with Lake Tahoe and Mammoth Mountain both operating full ski resorts, while Palm Springs and the desert cities see their most comfortable temperatures of the year.
