The Clay Trails are mainly gravel, easy for walking and cycling and most are suitable for horse riding too.
Some trails and pathways are also available to those using electric mobility scooters.
The Par Beach to St Blazey trail passes through the local nature reserve, St Andrew's Park, the railway station and the old river estuary marshes.
A footpath links St Blazey to Eden; cyclists can use nearby Cornhill Lane, which is quiet but hilly.
Bugle to Eden is a relatively easy trail. It has one moderate climb, which passes woodland and a picnic shelter overlooking fishing lakes.
Wheal Martyn to Eden is slightly more difficult. It has some steep slopes but offers spectacular 360-degree panoramic views of St Austell Bay and the clay mines.
The Eden Project offers discounts and fast-track queuing to people arriving on foot or by bike.
This popular visitor attraction is also a research facility and education resource, aiming for carbon-neutrality.
