Tri-Rail is a commuter line that links Miami, Ft. Lauderdale, and West Palm Beach. It has 18 stations on the Southern Floridian coast. Boca Raton is on the line, as are nearby Delray Beach and Boynton Beach.

However, as for public transportation around Boca Raton herself, there is essentially none, so be sure to rent a car (see the "Taxis and Rental Cars" page for some car rental companies). The sprawling, manicured lawns on Boca are spread out, and it would make no sense to try walking almost anywhere.
There are several places that walking is enjoyable however (AFTER you’ve taken a car there!). Stroll the upscale shops of Mizner Park, or even better, head to nearby Delray Beach and walk down Atlantic Avenue, admiring the shops and the (slightly) more laid-back, artsy atmosphere than you’ll find anywhere in Boca.
