The Eden Project and the Lost Gardens of Heligan are just a short drive away, as are the towns of Mevagissey and Fowey. Bodmin Gaol and the Bodmin & Wenford Steam Railway are also worth a visit. There are also several private and NT stately homes and gardens in the vicinity which are well worth a visit such as:
Lanhydrock House, Trerice, Trelissick
St Austell town is just a couple of minutes by car, has all local town amenities, including two 24 hour supermarkets.
St Austell is also on the main London-Penzance railway line and the station is only approximately 1.75 miles away with easy connections to Plymouth, Bodmin, Truro, Penzance, St Ives and beyond...(...useful for off season breaks and/or as a change from driving!).
