Bus traveling from Portland Oregon

While there is no direct bus between Portland and San Diego, you can take a bus to Los Angeles and then a different bus from L.A. to San Diego.

The Greyhound bus leaves Portland each day at 18:50 and arrives in Los Angeles the following day at 18:00, taking just over 23h. It makes around 18 stops throughout the journey. The journey costs between $95 and $135 for an economy ticket or $135 to $215 for a flexible ticket.

From L.A. to San Diego, there are two options. First, you can continue on Greyhound services with a bus that leaves at 18:30 and arrives at 22:10.

This makes your whole journey under 27 hours long with a 30-minute wait for the transfer in L.A. However, should your first leg be delayed, you run the risk of having to wait until the following day for the next Greyhound bus.

If you want to get a public bus from L.A. to San Diego, there are many changes. Essentially, you need to travel to Pacific/Florence (18-minute journey, Metro Los Angeles No. 60), then take the next bus at Huntington Park to San Ysidro (2h30m, Tufesa).

Bus from Portland to San Diego

There are three types of bus tickets available on Greyhound services. The flexible ticket is 100% refundable and exchangeable without fees.

You are allowed two under-the-bus bags included in the ticket price and one carry-on back. You also get priority boarding. With Economy Extra, you get priority boarding, one under-the-bus bag, and a free same-day exchange.

You can book tickets online or at the station. It’s a good idea to book in advance rather than turning up as tickets sell out quickly.

For people who want to pay for their ticket in cash, it is possible to reserve the ticket online and then pay for it and collect it at a nearby 7-eleven. It’s also possible to pay cash at the bus station and with many ticket retailers.

Greyhound operates a loyalty program called Road Rewards that gives you points for every trip you complete. Your points can turn into discounts and free tickets. Anyone can sign up for the loyalty program, and it’s completely free to join.

Different ticket types get you more points. For example, the flexible ticket gives you three points, the Economy Extra gives you two points, and the Economy gives you one point.

With 6 points, you get 15% off your next ticket or a free companion pass, or 10% off your food at a Greyhound Station. Ten points get you 20% off your ticket or a companion pass, and 16 points get you a free ticket anywhere.

Getting the best deals

For many people, the price is important when looking at travel options. So here are some ways of making sure you get the best price for your tickets no matter your way of traveling.

  1. Reserving a ticket in advance will guarantee you’ll pay less. Typically, tickets are much more expensive the closer you are to your departure date.
  2. It is usually less expensive to travel in the middle of the week or on holidays, so if it’s possible to choose which day you travel, look for mid-week prices.
  3. Tickets are usually cheaper if you buy them online and not in person at the station or through a travel agency.
  4. Look for voucher codes and promotions codes from travel websites and the travel company’s social media pages.
  5. Subscribe to any travel reward systems you can (like Greyhound’s points system).
  6. Make sure you use any discounts you’re entitled to – military tickets, senior tickets, and minors have cheaper options.
