As in much of Cornwall and neighbouring counties, tourism is increasingly important to St Austell's economy. Tourists are drawn to the area by nearby beaches and attractions such as the Eden Project, sited in a former clay pit, and the Lost Gardens of Heligan. The China Clay Country Park, in a former china-clay pit two miles north of the town, tells the story of the men, women and children who lived, worked and played in the shadow of the clay tips around St Austell.
St Austell is home to several public houses, numerous high street retailers, and several independent shops, many of which cater for tourists. The town has a small museum which is situated in the Market House. A Brewery Museum and Visitor Centre is situated on the site of the St Austell Brewery in Trevarthian Road.
