When we visited the Eden Project a few years ago we stopped at Innis Inn. I believe it is open all year, has a fly fishery and a B&B with restaurant and bar. It was about a miles walk away from the Eden Project.
Doubletrees Farm at St Blazey Gate - on Luxulyan Rd.
Easy walk to Eden :thumb::thumb:
Beautiful site - amazing views of St Austell Bay. Near to Four Lords pub / garage / post office / shop / cafe / bus stop.
See site review!
Don't know if it will be open but def worth a look!:thumb:
