The Galveston Trolley has recently been expanded into the UTMB area of town so that patients, residents, etc. may get to and from without paying a dime. This is a great addition for those who can utilize it, and I strongly urge those who can to take part. But the trolley also goes around the strand and even out to the Seawall side of the island. If you don't want to drive, or just want to see some sites from the comfort of a trolley car, hop on and enjoy.
Bottom Line: Good service at a good price (especially when it's free).
