San Marino is a small town surrounded by larger cities, so renting a car is the most convenient way to get around. However, public transportation options like buses and trains run regularly through the neighboring cities. Travelers should consider the cost of gas and parking when driving around.
If you have more time, consider visiting nearby attractions such as the Norton Simon Museum, Los Angeles County Arboretum & Botanic Garden or the Santa Anita Park. On the contrary, if you have less time, shorten your stay at Lacy Park. Make sure you check weather forecasts and dress accordingly.
