The Gaslamp Quarter bustles day and (more so at) night, and exploring the area on a guided walking or Segway tour is a fun way to take in the sights no matter the time of day. The neighborhood is visited on most San Diego city sightseeing tours and is a highlight of San Diego pub crawl tours. Top Gaslamp Quarter sights include the streets lined with historic buildings, some beautifully restored to their 19th-century architectural glory; Horton Plaza Park and its grassy lawns and interactive fountain; an array of boutiques; and the 5-story Westfield Horton Plaza mall set on the district’s eastern border. Along with its many shops and cultural offerings, the district has the city’s highest concentration of bars, nightclubs, and restaurants—making it the No. 1 place to be after dark.
