I view San Diego as a sleeper travel capital. By that, I mean that, though popular and well-known, the city doesn’t get enough credit for its well-rounded offers.

There are tons of activities on the water, from the harbor to the bay to those famous sea caves. In terms of culture, San Diego packs a punch when it comes to sports, nightlife, and public spaces like the paved Embarcadero Marina Park North and the LithoMosaic at Kellogg Park.
It even has its own Old Town historic district. And a Sea World. That’s not even mentioning the year-round sunshine and clear skies.
There’s also another huge perk: San Diego is a stone’s throw from Mexico. While Tijuana, the city that sits 20 miles away across the border, isn’t always viewed as a day trip destination, you can get in and out without too much trouble.
That is, if you have a tour company leading the way. Getting back and forth across the border can be a bit of a headache (a stressful one) if you’ve never done it before. Here’s how to offload to qualified tour companies that offer day trips from San Diego to Mexico.
Border Tours is the most accessible travel company for anyone who wants to zip down to Tijuana from San Diego. You’ll notice that they run most of the tours available on TripAdvisor and Viator. Below, you can also find wine tours directly on their website.

Mexico Wine Tour from San Diego by Border Tours

This is the last offer that I’m listing from Border Tours, which you can book directly on their website. It’s a wine tour that takes you a bit further south than Tijuana to the Valle de Guadalupe area. Just be prepared for a full day of driving, border-crossing, and wine tasting. I also recommend reaching out to the hosts for advice on crossing the border—it’s unclear whether a guide is available to help you make the journey.
