Things to know about San Diego

San Diego is probably one of the least typical US cities one would imagine. Even though there is a downtown with skyscrapers and everything else any larger US city has to offer, the city is mostly characterized by its Hispanic influence. Even though only a 2 hour drive from Los Angeles, the city directly borders Mexico and that’s what gives San Diego this unique feel and a lot of history and sights. Below you can find a summary of the best attractions and everything you should know before travelling to San Diego.
