What is the best time of year to cycle this route?

The Clay Trails are managed for year-round accessibility. However, for the most pleasant cycling experience, spring and autumn offer cooler temperatures and beautiful scenery.

The terrain is varied. Many sections are off-road with gravel surfaces, while others are paved or consist of quiet country lanes. You'll encounter both relatively easy stretches and steeper climbs, particularly on the section leading towards the Eden Project. The route is rated as moderate due to its distance and elevation gain.

You'll pass by the impressive Treffry Viaduct, experience the unique post-industrial scenery of the Clay Trails with their white spoil heaps and turquoise pools, and visit the renowned Eden Project, including the Mount Recyclemore Sculpture.

Is this cycling loop suitable for families?

While many sections of the Clay Trails are traffic-free and suitable for families, this specific loop from St Austell via the Eden Project is rated as moderate. It includes some steep climbs and varied terrain that might be challenging for very young children or inexperienced cyclists. Families with older, more confident riders or those with electric bikes may find it enjoyable.

What type of bike is best suited for this trail?

Yes, you'll find options for refreshments. St Austell offers various cafes and pubs at the start or end of your ride. The Eden Project itself has multiple cafes and restaurants. Additionally, some villages or attractions along the wider Clay Trails network may offer further choices, so it's worth planning your stops.

What makes the landscape of the Clay Trails unique?

You'll cycle through a striking post-industrial environment featuring large white spoil heaps, often called the 'Cornish Alps,' and former clay pits that have filled with distinctive blue-green water. This dramatic scenery is now being reclaimed by nature, creating havens for wildlife amidst the industrial heritage.
