Day Trips That Fit One Day From LA
Griffith Observatory and Santa Monica sit inside the city, so they are not really day trips; a genuine day trip from Los Angeles clears the metro area entirely. These four hold up to a single day without an overnight bag.
Catalina Island
High-speed Catalina Express catamarans reach Avalon from Downtown Long Beach and San Pedro in about 60 minutes. Round trip fare runs roughly $84 to $92 for an adult, plus a mandatory $10 wharfage tax, putting the real total near $94 to $102; children 2 to 11 run about $75. Avalon itself is pedestrian-friendly, with shore snorkeling and diving through the kelp forest at Casino Point Marine Park. Check ferry schedules and fares at catalinaexpress.com ; reserve ahead, since summer sailings fill.
Santa Barbara by train
The Pacific Surfliner runs direct from LA Union Station to Santa Barbara Station, two blocks from the beach, in 2 hours 15 minutes to 2 hours 40 minutes, five times daily each way. One-way coach fare runs $31 to $40 per adult, with free Wi-Fi and a cafe car onboard, and it skips the weekend US-101 backup entirely. Check timetables at pacificsurfliner.com . Or browse Santa Barbara day tours on GetYourGuide for a guided version with wine tasting built in.
Palm Springs and Joshua Tree, by car
Palm Springs sits 107 miles east, about 2 to 2.5 hours via I-10 outside peak traffic. The Aerial Tramway’s rotating cars climb 2.5 miles from the valley floor to 8,516 feet in 10 minutes, dropping the temperature by roughly 30°F; adult tickets run $32.95. Joshua Tree National Park, 130 miles east, charges a $30-per-vehicle fee valid for seven days; Hidden Valley’s loop, Barker Dam and Keys View cover the highlights. Both destinations turn genuinely dangerous in summer, with valley heat past 110°F and near-zero cell service inside Joshua Tree, so plan around the cooler months where possible.
Tips for planning your day trip
Catalina and Santa Barbara both work entirely on public transit; the desert side needs a rental car, since there is no practical bus or train link to either Palm Springs or Joshua Tree from the city.
The verdict
Pick one coastal option (Catalina or Santa Barbara) and one desert option per trip rather than trying both in the same visit; the transit and driving time do not overlap well. For a base near Union Station before an early train, compare Downtown LA hotels on Booking.com . See the multi-day trips guide for turning the desert side into its own two-day loop.
Before you go
Book Catalina Express and Pacific Surfliner seats several days ahead for summer weekends; both fill before the day of travel.
