A car is easiest for the whole county, but downtown, Old Town, Mission Valley, UTC and the border are well covered by the Trolley, and MTS buses reach Balboa Park, the Zoo and the beaches. Fares are $2.50 a ride with a $6 daily cap through PRONTO.
It's solid along the Trolley corridors and the coastal rail line, and weak in the suburbs. Visitors staying downtown, in Little Italy, Old Town or Coronado can get by without a car; day trips inland or to North County are much easier with one.
$2.50 per Trolley or bus ride with two-hour transfers, capped at $6 per day and $72 per month. COASTER fares are $5.00–$6.50 one way depending on how many zones you cross, and they are not capped — tap on and tap off.
Yes — Amtrak's Pacific Surfliner runs about a dozen round trips a day between Santa Fe Depot and LA Union Station in roughly 2 hours 45 minutes for $40–$50 in coach.
