San Diego, the beautiful city by the Pacific Ocean, about two hours south of Los Angeles, has arguably the best climate in the US and a healthy, laid-back attitude too. It has a great ethnic and cultural mix, and its close proximity to Mexico – Tijuana is less than 20 miles away – makes for great Mexican cafes and restaurants.

Food lovers coming off their flights to San Diego will find excellent Latin, Central and East Asian, Middle Eastern, Italian, Greek, and Pacific Islander food throughout the city. Pick up the scent in the Gaslamp Quarter, Little Italy, La Jolla and Old Town.

The beaches, climate and deserts are not the only things on offer. San Diego has several world-class attractions including Balboa Park, America’s largest urban cultural park, which has more than a dozen museums as well as the world-famous San Diego Zoo.

And for those travellers booking their San Diego flights to get away from it all, Torrey Pines State Reserve is one of the wildest landscapes along the coast, with unspoilt beaches, chaparral, pine trees and a lagoon vital to many migrating birds.

  • Deep discounts are available at the ARTS TIX booth downtown in Horton Plaza Park, where day-of-show tickets are available on a cash-only basis. Events include theatre, concert and dance throughout the city.
  • Each July, Mission Bay is home to a San Diego original, the Over-the-Line Tournament. This beach softball event dates from 1953 and is renowned for boisterous, anything-goes behaviour.
