There is no trainline to this town, so the only alternatives are buses or cars.
There's usually one bus an hour to Cirencester from Swindon, Cheltenham and Stroud.
A car may be a better option. Parking in Tescos or waitrose supermarket carpark then walking in is probably your best bet.
The town is small enough to walk around on foot. Discussions have been taking place as to whether the centre of town (infront of the church) should be pedestrianised - these have been going on for years, so don't hold your breath.
There are the typical high-street chains here too. But there are some special shops. Sadly Jeraboams has decided to close.
