Best day trips from San Diego: how to get there and what to see
Drive or take the train north to the beach towns, east to the mountains and desert, or south across the border. Pick one per day: a car gives the most freedom, the Coaster and Amtrak cover the coast, and Catalina needs a ferry booked ahead. Without a car, stay on the rail line.

The choices at a glance
San Diego sits between ocean, mountains and desert, with Mexico 30 minutes south and Los Angeles under three hours north. That range is the point: you can surf in the morning and stand in pine forest by mid-afternoon.
Use the table to pick by time and transport, then read the detail below for the practical bits.
| Day trip | Time from downtown | Best for | Car needed |
|---|---|---|---|
| La Jolla | 20 min | Sea lions, kayaking, snorkelling | No |
| Encinitas and Carlsbad | 30–50 min | Beaches, surf towns, flower fields in spring | No (Coaster) |
| Oceanside | 1 h | Harbour, pier, Mission San Luis Rey | No (Coaster) |
| Julian | 1–1.5 h | Mountain town, apple pie, gold-rush history | Yes |
| Mount Laguna | 1 h | Pines, cooler air, hiking | Yes |
| Anza-Borrego Desert | 2 h | Spring wildflowers, badlands, dark skies | Yes |
| Temecula | 1 h | Wine tasting, hot-air balloons | Yes |
| Los Angeles | 2 h 45 min | Museums, Hollywood, food | No (Amtrak) |
| Catalina Island | 1.5–2 h by ferry | Island walks, snorkelling, Avalon | No |
| Tijuana | 30 min | Food, markets, border crossing | No (trolley) |
Times are off-peak; add 30–60 minutes on weekday mornings and Sunday evenings.
The day trips in detail
La Jolla is the easiest win: 20 minutes north of downtown by car or bus, with the cove, the sea lions at Point La Jolla and kayak or snorkel tours from the beach. Go early — parking fills by mid-morning in summer.
The North County coast runs on the Coaster commuter train from Santa Fe Depot. Encinitas and Carlsbad are beach towns with surf breaks and, in spring, the flower fields near Carlsbad. Oceanside is the end of the line, with a working harbour and pier.
Inland, Julian is a former gold-mining town in the mountains, known for apple pie and cooler air; Mount Laguna is pine forest and trailheads an hour east. Anza-Borrego Desert State Park is two hours out and best in a wet spring, when wildflowers cover the badlands — check bloom reports before driving.
Temecula, an hour north, is the local wine country, with tasting rooms and balloon flights at dawn. Los Angeles is a full day by Amtrak Pacific Surfliner from Santa Fe Depot, arriving at Union Station; you can reach Hollywood or downtown without a car, but you will not see much of the city in one day.
Catalina Island is a ferry ride from Long Beach or Dana Point to Avalon, with walks, snorkelling and a small town; book the ferry ahead, especially in summer. Tijuana is 30 minutes south on the Blue Line trolley to San Ysidro, then a walk across the border — bring your passport, and expect a queue coming back.
- Book Catalina ferry and Amtrak seats before you go in summer.
- Start northbound trips before 8am to beat traffic and parking.
- Check Anza-Borrego wildflower reports in February–April.
- Carry your passport for Tijuana; the return queue can run an hour or more.
What it costs
Public transport is the cheap option: a Coaster or Amtrak ticket and a day of local buses will usually cost less than a rental car plus fuel and parking. Rental cars start around US$50–80 a day in peak season (2026 estimate), and parking at beaches and in La Jolla can add US$10–25.
Catalina ferry fares and wine tasting in Temecula are the two trips where the activity, not the transport, sets the budget. Check current fares and tasting fees before you commit.
| Item | Typical cost | Note |
|---|---|---|
| Coaster day pass | Under US$15 (2026 estimate) | Check current fares |
| Amtrak to Los Angeles | US$35–45 each way (2026 estimate) | Book ahead for lower fares |
| Catalina ferry round trip | US$80–100 (2026 estimate) | Check operator fares |
| Rental car, one day | US$50–80 plus fuel (2026 estimate) | Parking extra |
| Temecula tasting fee | US$20–35 per winery (2026 estimate) | Check each winery |
All figures are 2026 estimates and change with season and demand.
Practical tips
Traffic is the main variable. Northbound I-5 and I-15 are slow on weekday mornings; the coast route is easier on weekends if you leave early. Coming back from Los Angeles on a Sunday evening can add an hour.
If you are relying on trains, plan around the Coaster's weekday-only pattern and the Pacific Surfliner timetable, which is thinner at weekends. An eSIM keeps maps and tickets working across the border.
- Leave before 8am for anywhere north or east.
- Check Coaster and Amtrak timetables the day before; weekend service is limited.
- Keep a light jacket — the coast can be 10 °C cooler than inland.
- For the desert, carry water and check the forecast; summer heat is dangerous.
Questions people ask
What are the best day trips from San Diego?
La Jolla and the North County coast for beaches, Julian and Mount Laguna for mountains, Anza-Borrego for desert, and Los Angeles or Catalina Island for a full day. Tijuana is the shortest international trip.
Can I visit these places without a car?
Yes for the coast: the Coaster reaches Encinitas, Carlsbad and Oceanside, and Amtrak runs to Los Angeles. Catalina is ferry-only. Julian, Mount Laguna, Anza-Borrego and Temecula effectively need a car.
How long do day trips from San Diego take?
La Jolla is a half day. The coast towns and Julian take most of a day. Los Angeles, Catalina and Anza-Borrego are full days, and Catalina is easier as an overnight.
Do I need a passport for Tijuana?
