Plan a trip to San Jose
Founded in 1777 by the Spanish to support California’s missions, San Jose started as a quiet farming community of grape vineyards and apricot orchards. It wasn’t until the post-World War II boom that the city began its transformation, with returning veterans and tech giants like IBM planting the seeds for Silicon Valley. Today, San Jose blends its tech-driven vibe with natural beauty and a diverse mix of attractions. Start your day with a sunrise hike or bike ride on the Los Gatos Creek Trail or shop till you drop at San Jose's upscale Santana Row district.
