Walking is the best way to get around the city centre of Mobile, but for those travelling farther afield renting a car is a popular option. Driving is easy and relatively stress-free in and around Mobile. However, those wanting to use public transport should make use of the Moda, a free electric trolley system that links many tourist attractions, hotels and shopping centres. The Moda runs from Monday to Friday, from 7am to 6pm. Taxis are readily available outside these times. The Wave Transit System is a public service that is useful for getting around the city, too.
