Certainly be able to park it bob,clearance wise can only say that my astra made it ok with care so if your van is no lower than an average car it should be ok.The parking spot is probably just under a mile from corriechoille farm but don't think you can park down there
.You could try and find some place on the minor road but this would add a bit onto an all ready long walk,a bike could be an option.Enjoy it when you go
