Downtown features colorful skyscrapers, smaller businesses, and a constant flow of people and cars. It seems like each person in this busy area is there for a purpose. Go shop, explore the Gaslamp Quarter where modern and historic buildings stand side by side, or make a day of it watching a Padres game at Petco Park. Club crawls and festivals take place throughout the year. As a result, parking is a challenge on the best of days but there are a number of affordable paid lots you can walk from to your destination.
