Try the free state park lots first, then the surrounding streets — and skip driving entirely on festival days.
Last updated
The state park's free visitor lots off Twiggs and Calhoun streets is the first thing to try in Old Town. State historic park visitor lots are free, and there is free time-limited street parking on the surrounding blocks, so most visitors do not need a paid lot at all — but the free lots are small and fill by late morning on weekends. Private lots around San Diego Avenue are the fallback when they are full. Weekend lunch hours, Cinco de Mayo, Día de los Muertos and other festival days are the hardest times to drive here, and Old Town Transit Center is served by the Blue and Green trolley lines, the COASTER, Amtrak and several bus routes, which makes arriving without a car unusually easy for a San Diego attraction. Read the posted limit on the exact block or lot you use; signs control, and they differ street by street.
| Option | Best for | What to know |
|---|---|---|
| State park visitor lots | The historic park and plaza | Free, small, and usually full by late morning on weekends |
| Streets off Twiggs and Congress | Short visits to the plaza | Free with posted time limits that vary by block |
| Private lots near San Diego Avenue | Longer meals and shopping | Paid; read the posted rate and closing time at the entrance |
| Old Town Transit Center | Trolley, COASTER and Amtrak arrivals | A short walk to the plaza; the easiest option on festival days |
| Park-and-ride for downtown | Ballgames and downtown nights | Trolley from Old Town avoids downtown event parking entirely |

Off Twiggs and Calhoun streets · Free; closest to the plaza
These lots serve the state historic park directly and cost nothing. They are also the smallest part of Old Town's parking supply, so treat a full lot as the signal to move to the street grid rather than waiting in the entrance lane.
Free with posted limits
Blocks north and east of the park usually turn over faster than the lots. Read the sign on the exact block — the limits are not uniform, and a restriction remembered from another street is not a defence.
Paid fallback
Commercial lots along and behind San Diego Avenue take the overflow on busy afternoons. Check the posted rate and the closing time at the entrance before you walk away; rates are set by the operator and change.
Cinco de Mayo, Día de los Muertos and other events fill every lot early and change traffic around the plaza. The trolley is the reliable plan on those days.
The middle of a weekend day is the tightest window. Arriving before mid-morning, or after the lunch rush, is more reliable than hunting for a space at noon.
Old Town Transit Center works as a park-and-ride for downtown: leave the car here and take the trolley rather than paying event pricing near the ballpark.
Yes, in part. The state historic park's visitor lots are free, and surrounding streets have free time-limited parking. Those lots are small, so private paid lots around San Diego Avenue take the overflow on busy days.
Start with the park's own visitor lots off Twiggs and Calhoun streets. If they are full, use the street grid a few blocks out and walk in rather than circling the plaza.
Weekend lunch hours and festival days such as Cinco de Mayo and Día de los Muertos. On those days the trolley to Old Town Transit Center is the more reliable plan.
Yes. Old Town Transit Center is served by the Blue and Green trolley lines, the COASTER, Amtrak and several bus routes, and it is a short walk from the historic park.
Yes, that is a common local move for Padres games and downtown nights out. Check the posted limit where you leave the car, since not every space allows a long stay.
