Your tour starts downtown in the morning (hotel pickup provided from select locations), where you'll meet your guide for your exploration of San Diego. Visit neighborhoods including Little Italy, East Village, and the Gaslamp Quarter, home to restaurants, bars, and galleries.
Drive north of the city to the upscale coastal community of La Jolla, known for its rocky shore and sea caves, and visit Balboa Park, the jewel of San Diego. Then check out Old Town San Diego State Historic Park, the 'birthplace of California.' Throughout your 4-hour tour, learn about San Diego's history and culture from your guide.
Next, you have a 1-hour break to get some lunch (own expense) before continuing the second half of your tour—traveling about 15 minutes to the US-Mexico border, from where you'll head into Tijuana.
Visit attractions such as Mercado Hidalgo, the River Zone (Zona Rio), and Avenida Revolucion, one of the main streets of town, and perhaps enjoy local cuisine at a restaurant (own expense) or bargain for souvenirs. When your time here ends, you'll be returned to San Diego to end your tour.
