San Gabriel is a small town, so walking or biking are great options for getting around. If you need to travel farther, ride-sharing apps or renting a car are both good choices. For those on a budget, public transportation is available -- the nearest metro station is Sierra Madre Villa, which is a 15 minute drive from San Gabriel.
If you have more time, consider visiting the San Gabriel Square Mall for some shopping, or the Vincent Lugo Park for a picnic and some outdoor fun. If you have less time, consider skipping Santa Anita Park or the honey-tasting at the Huntington Library and Botanical Gardens to save on costs.
