San Diego is a city that rewards the curious traveler. Once you step beyond the beaches and boardwalks, you’ll discover neighborhoods layered with culture, history, local food, and sweeping coastal overlooks. And while most visitors instinctively grab a rental car or ride-hail app, locals know that the San Diego bus system is the true under-the-radar travel hack.
Unlike the trolley (which follows a predictable spine), the bus network is what actually takes you into the heart of the neighborhoods you want to explore. From La Jolla’s dramatic coastline to North Park’s brunch scene, from Balboa Park to Hillcrest to Ocean Beach, the buses are where the magic — and the real San Diego — unfolds.
This guide is built for travelers who want more than the typical “tourist loop.” You’ll get local insider insights, scenic routes worth riding, exact lines to use, strategies to avoid confusion, and advanced hacks to help you craft the perfect San Diego itinerary — all using the MTS bus network.
Let’s hit the road (but without the car).
Understanding the San Diego Bus System Like a Local
The San Diego bus system is run by MTS (Metropolitan Transit System), and it’s surprisingly extensive, covering coastal towns, inland neighborhoods, and destinations that the trolley simply doesn’t reach.
Travelers usually overlook buses — and that’s the exact reason they’re so useful. They’re less crowded, more frequent on key corridors, and incredibly flexible for crafting an explorer-style day.
The Three Types of Buses You’ll Actually See
1. Local Buses (Numbers 1–899)
These connect neighborhoods, landmarks, beaches, and parks. They’re your bread-and-butter routes.
2. Rapid Buses (200s & 300s)
These use freeway medians or limited-stop routes, making them faster than local buses. If you want speed, choose Rapid.
3. Express Routes
These mainly serve commuters and are less helpful for visitors unless you’re doing long-distance segments.
The Key Takeaway
You don’t need to master the entire bus system — just a handful of local-favorite routes that take you straight to the good stuff.
This article focuses entirely on those routes.

Insider Hacks for Using the San Diego Bus System
These are real local tricks that make riding easier, faster, and far more enjoyable.
Hack 1 — Always Use Google Maps Transit Mode
San Diego buses can be confusing at first glance. Google Maps uses real-time tracking, so you’ll know:
- Exact arrival times
- Which side of the street the stop is on
- Whether a Rapid bus is faster
Key takeaway:
Never trust outdated paper maps. Always use real-time transit.
Hack 2 — Tap to Ride (No Pass Needed)
Just tap your credit card, debit card, or phone at the reader. You’re charged the same price as a regular fare.
This is great for travelers who don’t need a multi-day pass.
Hack 3 — Choose Rapid Routes Whenever Possible
Rapid buses are:
- More comfortable
- More reliable
- Faster
- Less prone to random stops
If you’re choosing between a local route and a Rapid and both reach your destination, pick the Rapid.
Hack 4 — Use Buses as Scenic Routes
Some of the most beautiful drives in San Diego are actually bus corridors:
- Route 30 along the coastline
- Route 923 toward Ocean Beach
- Rapid 215 around Balboa Park
- Route 7 along the historic Mission Valley corridor
These are perfect for photography days.
Hack 5 — Avoid the Bottom of the Hill in La Jolla
Locals know:
La Jolla’s hills are steep.
Bus stops at the bottom mean you’ll be hiking uphill for a long time.
Plan routes that exit near La Jolla Village or Prospect Street.
