From Plymouth, take the A38 to Liskeard, then the A390 from Liskeard to St Blazey.
Go over level crossing at St Blazey, see garage on left, take right turn signposted ‘Eden Project’, then first right and you’re there.
From Truro take the A390 to St Austell, and continue to St Blazey. Go through St Blazey and at the first sign for the Eden Project, turn left then first right for Woodmill.
Main line station: Par Station is within 1 mile and Newquay Airport is 30 minutes away.
St Blazey, with shops, two pubs serving food and a Post Office, is only 300 metres away.
To get here via the A30:
Take the St Austell turnoff, which is the A391. Continue on this road until you reach a T-junction with traffic lights, then turn left onto the A390 towards St Blazey, Par and Fowey. After about half a mile, you'll come to a roundabout; go straight over, which will bring you to St Blazey Gate. Drive through, and you will come to St Blazey itself. Keep going until, when you are almost through St Blazey, you see a filling station on the right. Directly opposite the filling station, turn left onto Prideaux Road (signposted 'Eden Project') and Woodmill Farm is about a hundred yards along on the right. On the map on the left, follow the blue line.
