    San Diego Bus Guide: Routes, Fares & the Ones Worth Riding

    Buses fill in everywhere the Trolley doesn't go — Balboa Park, the beaches, North Park, La Jolla — and the Rapid lines run frequently enough that you don't need a schedule.

    Quick answer

    MTS local buses cost $3 for most adult one-way trips ($7 daily cap with PRONTO) and cover the places the Trolley misses. The most useful routes for visitors are the paid Route 992 from the airport, Route 7 to Balboa Park and the Zoo, Routes 8/9 to Mission and Pacific Beach, and Rapid 215 up El Cajon Boulevard to North Park and SDSU.

    Getting to the Zoo and Balboa Park

    Route 7 from downtown runs along Park Boulevard and stops at the Zoo entrance and the Balboa Park museums — about 15 minutes from the Gaslamp and far cheaper than the $20 park-adjacent lots on busy weekends. Rapid 215 also serves the park's eastern edge.

    Getting to the beaches

    Take the Trolley to Old Town, then Route 8 or 9 to Mission Beach and Pacific Beach, or Route 30 for Pacific Beach and La Jolla. The full trip from downtown runs 40–55 minutes; on a July Saturday it beats hunting for beach parking.

    Local tips

    • Tap PRONTO or pay exact cash; drivers can't make change.
    • Rapid lines have their own red stations and level boarding — use them when the route overlaps a local.
    • Bike racks are free and hold two bikes; load from the curb side.
    • Late-night frequency drops sharply — check the last departure if you're out past 10pm.
