Clarkes Top-Oil is the closest location for petrol or diesel. Clarke’s are not only in the fuel business but they also have a small grocery shop, a pub and a funeral parlour ( hopefully you won’t be needing the latter ). 

The grocer shop stays open while the pub is open so if you realise that you need essentials late in the evening then you’re in luck. 

Clarkes is 4.2 km from the cottage, a 5 minute drive.
